Description

熱壓鍵合裝置 Hot pressing bonding device

本發明提供一種熱壓鍵合裝置，更詳細地，提供一種利用熱壓將晶片鍵合於基板上的熱壓鍵合裝置。 The present invention provides a thermocompression bonding apparatus, and more specifically, a thermocompression bonding apparatus for bonding a wafer to a substrate by using a thermocompression.

將半導體晶片附著於電路板上的製程，一般需要非常精確地執行，基板上具有固定半導體晶片的多個安裝區域。另一方面，半導體晶片與電路板的安裝區域需要進行準確地電連接，為了減少不合格率，半導體晶片需要安裝在安裝區域的正確位置(圖案)。 The process of attaching a semiconductor wafer to a circuit board generally needs to be performed very accurately, and the substrate has a plurality of mounting areas on which the semiconductor wafer is fixed. On the other hand, the mounting area of the semiconductor wafer and the circuit board needs to be accurately electrically connected. In order to reduce the failure rate, the semiconductor wafer needs to be mounted at the correct position (pattern) of the mounting area.

半導體晶片的安裝製程可以稱為鍵合製程。基於要求精確的作業的製程特殊性，對電路板整體位置和電路板半導體晶片的固定部位置(安裝區域)進行檢查，然後將半導體晶片安裝於電路板上。 The mounting process of a semiconductor wafer may be referred to as a bonding process. Based on the specificity of the process that requires precise work, the overall position of the circuit board and the position of the fixed portion (mounting area) of the semiconductor wafer of the circuit board are checked, and then the semiconductor wafer is mounted on the circuit board.

熱壓鍵合裝置是指從晶圓分離出單獨的半導體晶片，用鍵合拾取器以晶片底部(凸塊形成面)朝下的方式拾取晶片的狀態下，將晶片鍵合於物件基板上的裝置。 A thermocompression bonding device refers to a state in which a separate semiconductor wafer is separated from a wafer, and the wafer is bonded to an object substrate with the bonding picker picking up the wafer with the wafer bottom (bump formation surface) facing downward. Device.

晶片鍵合方法有：向凸塊塗布助焊劑，並將其附著於基板的接線端子的方法和在基板上塗布助焊劑並將接線端子附著於基板的方法。此時，半導體晶片以加熱的狀態被擠壓，這種方法稱為熱壓方式。 The wafer bonding method includes a method of applying a flux to a bump and attaching it to a terminal of a substrate and a method of applying a flux to a substrate and attaching a terminal to a substrate. At this time, the semiconductor wafer is pressed in a heated state. This method is called a hot pressing method.

但是，這種熱壓方式中，因鍵合拾取器擠壓晶片時的壓力，使黏合件從側面向上流動並黏到鍵合拾取器底部，或者因加熱黏合件期間產生的氣體，會出現鍵合拾取器被污染的問題。 However, in this hot-pressing method, a bond may flow from the side up and stick to the bottom of the bond picker due to the pressure when the bond picker presses the wafer, or a bond may occur due to a gas generated during heating of the bond member. The problem that the pickup is contaminated.

另一方面，對於習知的熱壓鍵合裝置來說精度比較重要，但藉由龍門架移動鍵合拾取器時，因基於X軸和Y軸的移動發生振動而無法確保精度，並且，當一個鍵合拾取器作業期間另一個鍵合拾取器同時作業的情況下，無法驗證其精度，因而，在熱壓鍵合裝置中，一個晶圓只能用一個鍵合拾取器進行熱壓鍵合。因此，習知的熱壓鍵合裝置只能是低產量(UHP)的裝置。 On the other hand, accuracy is important for the conventional thermocompression bonding device. However, when the bonding picker is moved by a gantry, the accuracy cannot be ensured due to vibrations caused by the movement of the X-axis and Y-axis. During the operation of one bond picker, the accuracy cannot be verified when another bond picker is operated at the same time. Therefore, in a thermocompression bonding device, one wafer can only be thermocompression bonded by one bond picker. . Therefore, the conventional thermocompression bonding device can only be a low-yield (UHP) device.

另一方面，韓國公開專利第10-2000-0035067中公開了一種翻轉半導體晶片並直接鍵合在基板上的熱壓鍵合裝置。 On the other hand, Korean Published Patent No. 10-2000-0035067 discloses a thermocompression bonding device that flips a semiconductor wafer and directly bonds it to a substrate.

At this time, while the suction head is moving in the X-axis direction, while the semiconductor wafers are sequentially bonded along the same line in the X-axis direction, the transfer robot can move along the Y The wafer carrier is moved in the axial direction. In other words, since the tip can operate in the same row when the semiconductor wafer is manipulated, it is not necessary to move in the Y-axis direction, so that the vibration generated by the tip can be minimized.

Mounted on the substrate.

參照第1圖和第2圖對本發明的一個即時例的熱壓鍵合裝置100進行說明。第1圖是本發明的一個實施例的熱壓鍵合裝置100的平面圖，第2圖是本發明的一個實施例的熱壓鍵合裝置100的側視圖。 A hot-press bonding apparatus 100 according to an instant example of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a plan view of a thermocompression bonding apparatus 100 according to an embodiment of the present invention, and FIG. 2 is a side view of the thermocompression bonding apparatus 100 according to an embodiment of the present invention.

熱壓鍵合製程可包括以下步驟：翻轉拾取器120吸附從晶圓切割的晶片；將翻轉拾取器120以上下方向旋轉180度，以使晶片的上面和下面翻轉；將吸附於翻轉拾取器120的晶片傳遞至單元拾取器130；檢查被單元拾取器130拾取的晶片底部；將晶片放置於片狀塊162上；鍵合拾取器140移動至打孔裝置170並對薄膜148進行穿孔；鍵合拾取器140移動至片狀塊162並吸附晶片；鍵合拾取器140移動至鍵合位置；檢查吸附至鍵合拾取器140的晶片和基板的接線端子間的對齊狀態；向鍵合拾取器140加壓並將晶片熱壓鍵合至接線端子上。 The hot-press bonding process may include the following steps: the flip picker 120 sucks the wafer cut from the wafer; rotates the flip picker 120 up and down 180 degrees to flip the top and bottom of the wafer; and sucks the flip picker 120 The wafer is transferred to the unit picker 130; the bottom of the wafer picked up by the unit picker 130 is checked; the wafer is placed on the sheet block 162; the bonding picker 140 is moved to the punching device 170 and perforated the film 148; bonding The picker 140 moves to the sheet block 162 and sucks the wafer; the bonding picker 140 moves to the bonding position; checks the alignment state between the wafer and the terminal of the substrate sucked to the bonding picker 140; toward the bonding picker 140 Press and bond the wafer to the terminals.

為此，本發明的一個實施例的熱壓鍵合裝置100，可包括：晶圓供給部110，供給被切割成單個晶片單元的晶圓；翻轉拾取器120，從晶圓供給部110拾取晶片；單元拾取器130，從翻轉拾取器120拾取晶 片；片狀塊162，放置單元拾取器130拾取的晶片；打孔裝置170，對位於吸頭141底部的薄膜148進行打孔；上視視覺155，檢查被單元拾取器130拾取的晶片底部(附著有凸塊的凸塊面)；狹縫視覺151，檢查吸頭141拾取的晶片與基板鍵合位置的對齊狀態；加熱台154，支撐基板。 To this end, the thermocompression bonding apparatus 100 according to an embodiment of the present invention may include: a wafer supply unit 110 that supplies a wafer cut into a single wafer unit; a flipper 120 that picks up a wafer from the wafer supply unit 110 ; Unit picker 130, pick crystal from flip picker 120 Sheet block 162, which holds the wafer picked up by the unit picker 130; a punching device 170, which punches the film 148 located at the bottom of the suction head 141; a top view 155, which checks the bottom of the wafer picked up by the unit picker 130 (Bump surface with bumps attached); slit vision 151, checking the alignment of the bonding position between the wafer picked up by the suction head 141 and the substrate; and a heating stage 154 supporting the substrate.

此外，本發明的一個實施例的熱壓鍵合裝置100可包括以下層和上層方式設置的雙層結構。下層可設置晶圓供給部110和翻轉拾取器120，上層台150可設置單元拾取器130、上視視覺155、吸頭141、狹縫視覺151、加熱台154等。 In addition, the thermocompression bonding apparatus 100 according to an embodiment of the present invention may include a two-layer structure provided in a lower layer and an upper layer manner. The lower layer may be provided with a wafer supply unit 110 and a flip picker 120, and the upper stage 150 may be provided with a unit picker 130, a top-view vision 155, a suction head 141, a slit vision 151, a heating stage 154, and the like.

並且，上層台150的部分開口，以便將晶片從設置在下層的翻轉拾取器120傳遞至設置在上層的單元拾取器130。 In addition, a part of the upper stage 150 is opened to transfer the wafer from the flip picker 120 provided on the lower stage to the unit pickup 130 provided on the upper stage.

晶圓供給部110包括放置晶圓的晶圓台111，晶圓台111可沿著第一方向軌道112向X軸方向移動，沿著第二方向軌道113向Y軸方向移動。晶圓台111可向X軸、Y軸方向移動，以便將作為拾取物件的晶片置於翻轉拾取器120能夠拾取的位置。 The wafer supply unit 110 includes a wafer stage 111 on which wafers are placed. The wafer stage 111 can move in the X-axis direction along the first-direction rail 112 and can move in the Y-axis direction along the second-direction rail 113. The wafer stage 111 can be moved in the X-axis and Y-axis directions so that a wafer as a pick-up object can be placed at a position that can be picked up by the flip picker 120.

翻轉拾取器120可從晶圓吸附晶片並傳遞至單元拾取器130。翻轉拾取器120包括在上下方向旋轉180度並將晶片上下面進行翻轉的翻轉頭121，翻轉頭121可沿著協力廠商向軌道122向Z軸方向移動。 The flip picker 120 may suck the wafer from the wafer and transfer it to the unit picker 130. The flip picker 120 includes a flip head 121 that rotates 180 degrees in the up-down direction and flips the top and bottom of the wafer. The flip head 121 can be moved in the Z-axis direction along the track 122 by a third party.

此時，當晶圓供給部110以形成在熱壓鍵合面上的凸塊朝上的方式供給晶圓時，晶片被翻轉拾取器120拾取後，藉由旋轉將上下位置進行翻轉，從而使形成凸塊的鍵合面朝下，藉由吸頭141吸附的吸附面朝上。 At this time, when the wafer supply unit 110 supplies the wafer with the bumps formed on the thermocompression bonding surface facing upward, after the wafer is picked up by the flip picker 120, the vertical position is reversed by rotation, so that The bonding surface forming the bump faces downward, and the adsorption surface adsorbed by the suction head 141 faces upward.

下面將詳細說明翻轉拾取器120的吸附過程，可藉由位於晶圓下方的推出器114的擊打，使單個晶片從晶圓中分離，翻轉拾取器120可藉由吸附等方式拾取晶片。並且，可在Z方向上同步控制推出器114和翻轉拾取器120，以將晶片從晶圓中分離。即，隨著推出器114的上升，翻轉拾取器120也一起上升，從而能夠執行晶片分離作業。另一方面，翻轉拾取器120的拾取方法，不僅有吸附方式更包括黏合方式，也可採用夾持(gripping)方式。 The adsorption process of the flip picker 120 will be described in detail below. A single wafer can be separated from the wafer by the impact of the ejector 114 located below the wafer, and the flip picker 120 can pick up the wafer by suction or the like. Also, the ejector 114 and the flip picker 120 can be controlled in the Z direction simultaneously to separate the wafer from the wafer. That is, as the ejector 114 rises, the reversing picker 120 also rises together, so that a wafer separation operation can be performed. On the other hand, the picking method of the flip picker 120 includes not only an adsorption method but also a gluing method, and a gripping method can also be adopted.

單元拾取器130可從翻轉拾取器120接收晶片，上視視覺155可檢查被單元拾取器130拾取的晶片的鍵合面。 The unit picker 130 may receive a wafer from the flip picker 120, and the top view 155 may inspect a bonding surface of a wafer picked up by the unit picker 130.

單元拾取器130可沿著第一方向軌道131向X軸方向移動，沿著協力廠商向軌道132向Z軸方向移動。另一方面，單元拾取器130的拾取方法，不僅有吸附方式更包括黏合方式，也可採用夾持(gripping)方式。 The unit picker 130 can be moved in the X-axis direction along the first-direction track 131, and can be moved in the Z-axis direction along the third-party track 132. On the other hand, the picking method of the unit picker 130 includes not only an adsorption method but also a gluing method, and a gripping method can also be adopted.

上視視覺155可檢查形成在晶片底部的凸塊的對齊狀態、凸塊的黏附狀態或凸塊的污染狀態等。此類檢查可依靠相機成像技術，其位於單元拾取器130的輸送路徑下部，以能夠朝上視方向(up-looking)成像的方式配置。 The upward vision 155 can check the alignment state of the bumps formed on the bottom of the wafer, the adhesion state of the bumps, or the contamination state of the bumps. This type of inspection can rely on camera imaging technology, which is located below the transport path of the unit picker 130 and is configured in such a way that it can image up-looking.

下面參照第3圖，對晶片搬運器160進行說明。第3圖是本發明的一個實施例的晶片搬運器160的平面圖。 Next, the wafer carrier 160 will be described with reference to FIG. 3. FIG. 3 is a plan view of a wafer carrier 160 according to an embodiment of the present invention.

參照第3圖，晶片搬運器160可包括：片狀塊162，放置藉由上視視覺155完成檢查的晶片；打孔裝置170，對供給至鍵合拾取器140 的薄膜148進行打孔。並且，晶片搬運器160可依靠搬運機器人161沿Y軸方向移動，依靠汽缸沿X軸方向移動。 Referring to FIG. 3, the wafer carrier 160 may include: a sheet-like block 162 for placing a wafer that has been inspected by the top-view vision 155; a punching device 170 for supplying to the bond picker 140 The film 148 is perforated. In addition, the wafer carrier 160 can move in the Y-axis direction by the transfer robot 161 and can move in the X-axis direction by the cylinder.

並且，晶片搬運器160可拆裝地設置。因此，當片狀塊162被污染或者打孔裝置170出現故障時可更換晶片搬運器160，從而能夠將製程中斷最小化。 The wafer carrier 160 is detachably provided. Therefore, when the chip block 162 is contaminated or the punching device 170 fails, the wafer carrier 160 can be replaced, so that process interruption can be minimized.

在片狀塊162上可以以凸塊朝下的方式放置晶片。並且，片狀塊162可形成有吸附晶片的吸附孔163。 The wafer can be placed on the sheet-like block 162 with the bumps facing downward. In addition, the sheet-like block 162 may be formed with a suction hole 163 for suctioning a wafer.

打孔裝置170可對薄膜148進行穿孔，以便能夠將鍵合拾取器140的真空壓力傳遞至晶片。下面將對打孔裝置170進行詳細說明。 The punching device 170 can perforate the film 148 so that the vacuum pressure of the bonding picker 140 can be transmitted to the wafer. The punching device 170 will be described in detail below.

第4圖是第3圖的另一個實施例的晶片搬運器160的平面圖。 FIG. 4 is a plan view of a wafer carrier 160 according to another embodiment of FIG. 3.

參照第4圖，晶片搬運器160-1中的片狀塊162和打孔裝置170可沿Y軸方向或沿垂直於鍵合拾取器140移動方向排列設置。第3圖所示的實施例的情況是，片狀塊162和打孔裝置170並非設置於同一軸線上，因此當吸頭141對薄膜148進行穿孔後，晶片搬運器160或鍵合拾取器140沿X軸方向移動，並拾取放置在片狀塊162上的晶片，此時，存在向X軸方向的移動使設備整體震動加劇的問題。 Referring to FIG. 4, the sheet-like block 162 and the punching device 170 in the wafer carrier 160-1 may be arranged along the Y-axis direction or in a direction perpendicular to the moving direction of the bonding picker 140. In the embodiment shown in FIG. 3, the sheet block 162 and the punching device 170 are not disposed on the same axis. Therefore, when the nozzle 141 perforates the film 148, the wafer carrier 160 or the bond picker 140 Moving in the X-axis direction and picking up the wafer placed on the sheet-like block 162, at this time, there is a problem that the movement in the X-axis direction exacerbates the overall vibration of the device.

因此，如第4圖所示，晶片搬運器160-1上的片狀塊162和打孔裝置170設置在Y軸的同一軸線上，從而鍵合拾取器140在晶片搬運器160-1與打孔裝置170之間移動時，在Y軸方向移動即可，無需向X軸方向移動。根據上述結構，能夠使藉由龍門架而移動的鍵合拾取器140的X 軸移動最小化，從而減少設備的振動，更佳地，使用第4圖中示出的晶片搬運器160-1。 Therefore, as shown in FIG. 4, the sheet-like block 162 and the punching device 170 on the wafer carrier 160-1 are disposed on the same axis of the Y-axis, so that the bonding picker 140 is placed between the wafer carrier 160-1 and the puncher 160-1. When moving between the hole devices 170, it is sufficient to move in the Y-axis direction, and it is not necessary to move in the X-axis direction. According to the above configuration, the X of the bond picker 140 that can be moved by the gantry can be changed. The shaft movement is minimized, thereby reducing the vibration of the apparatus, and more preferably, the wafer carrier 160-1 shown in FIG. 4 is used.

重新參照第1圖和第2圖，在上層台150上可設置一對晶片搬運器160。因此，一個單元拾取器130可依次將晶片放置於兩個晶片搬運器160上，從而能夠縮短製程時間。此外，鍵合拾取器140和狹縫視覺151可與晶片搬運器160的數量對應地在上層台150上設置一對。因此，當單元拾取器130從翻轉拾取器120接收晶片期間，兩個鍵合拾取器140連續執行將晶片鍵合於基板上的製程，從而能夠連續地進行製程，而不中斷。 Referring again to FIGS. 1 and 2, a pair of wafer carriers 160 may be provided on the upper stage 150. Therefore, one unit picker 130 can sequentially place wafers on the two wafer carriers 160, which can shorten the process time. In addition, a pair of the bond picker 140 and the slit vision 151 may be provided on the upper stage 150 corresponding to the number of the wafer carriers 160. Therefore, while the unit picker 130 receives the wafer from the flip picker 120, the two bonding pickers 140 continuously perform the process of bonding the wafer to the substrate, so that the process can be continuously performed without interruption.

下面對單元拾取器130的操作過程進行詳細說明，在單元拾取器130沿Z軸方向移動的同時，翻轉拾取器120拾取旋轉至凸塊朝下的晶片。並且，單元拾取器130沿X軸方向移動至上視視覺155的成像區域。 The operation process of the unit picker 130 is described in detail below. While the unit picker 130 moves in the Z-axis direction, the flip picker 120 picks up a wafer that is rotated until the bumps face downward. And, the unit picker 130 moves to the imaging area of the upward-viewing vision 155 in the X-axis direction.

當判斷上視視覺155的成像結果良好時，將晶片放置於晶片搬運器160的片狀塊162上。此時，搬運機器人161沿Y軸方向移動，使晶片搬運器160的片狀塊162位於單元拾取器130的下部。 When it is determined that the imaging result of the top-view vision 155 is good, the wafer is placed on the sheet-like block 162 of the wafer carrier 160. At this time, the transfer robot 161 moves in the Y-axis direction, so that the sheet-like block 162 of the wafer handler 160 is positioned below the unit picker 130.

或者，晶片搬運器160不移動，單元拾取器130沿Y軸方向移動，使晶片放置於晶片搬運器160的片狀塊162上。此時，單元拾取器130可藉由第二方向軌道(未圖示)引導至Y軸方向。 Alternatively, the wafer carrier 160 does not move, and the unit picker 130 moves in the Y-axis direction, so that the wafer is placed on the sheet block 162 of the wafer carrier 160. At this time, the unit picker 130 can be guided to the Y-axis direction by a second-direction track (not shown).

第5圖是表示鍵合拾取器140的側視圖。 FIG. 5 is a side view showing the bonding pickup 140.

參照第5圖，鍵合拾取器140可包括吸附放置於片狀塊162上的晶片的上表面的吸頭141。 Referring to FIG. 5, the bond picker 140 may include a suction head 141 that suctions an upper surface of a wafer placed on the sheet-like block 162.

吸頭141可移動至XYZ軸座標系空間的任意位置。例如，與吸頭141連接的頭部主體144可沿著設置在頭部機器145上的協力廠商向軌道147向Z軸方向移動。此外，頭部主體144可沿著設置在頭部機器145上的第一方向軌道向X軸方向移動。此外，頭部機器145可沿著設置在上層台150上的第二方向軌道146向Y軸方向移動。 The suction head 141 can be moved to any position in the XYZ axis coordinate system space. For example, the head body 144 connected to the suction head 141 may be moved in the Z-axis direction along a third-party track 147 provided on the head machine 145. In addition, the head body 144 can move in the X-axis direction along a first-direction track provided on the head machine 145. In addition, the head machine 145 can move in the Y-axis direction along a second direction rail 146 provided on the upper stage 150.

吸頭141可以以沿Z軸方向升降的方式設置。為此，可包括傳遞動力的馬達142和將馬達142的回轉力以直線往復運動方式傳遞的動力傳遞部件143。例如，動力傳遞部件143可包括蝸桿與蝸輪或者齒條和小齒輪等。 The suction head 141 may be provided to be raised and lowered in the Z-axis direction. To this end, a motor 142 that transmits power and a power transmission member 143 that transmits the turning force of the motor 142 in a linear reciprocating motion may be included. For example, the power transmission member 143 may include a worm and a worm wheel, or a rack and pinion.

並且，吸頭141可相對於頭部主體144以Z軸為中心自轉的方式設置。因此，當晶片在歪曲狀態下被吸附時，也能夠藉由吸頭141的旋轉，將晶片的凸塊與基板的接線端子位置對齊。 In addition, the suction head 141 may be provided so as to rotate around the Z axis with respect to the head body 144. Therefore, when the wafer is sucked in the distorted state, the bumps of the wafer can be aligned with the positions of the terminal terminals of the substrate by the rotation of the suction head 141.

並且，鍵合拾取器140可以以向晶片施加熱和壓力的方式設置。由設置在鍵合拾取器140上的發熱部產生的熱傳遞至晶片的凸塊。並且，在吸頭141下降的同時向晶片加壓。具體地，將晶片移動至基板的安裝位置，並向晶片施加熱和壓力時，凸塊變形，以將晶片和基板進行鍵合。此過程稱為熱壓鍵合。 And, the bonding picker 140 may be provided in such a manner as to apply heat and pressure to the wafer. The heat generated by the heat generating portion provided on the bonding pickup 140 is transferred to the bumps of the wafer. Then, the wafer is pressed while the suction head 141 is lowered. Specifically, when the wafer is moved to the mounting position of the substrate and heat and pressure are applied to the wafer, the bumps are deformed to bond the wafer and the substrate. This process is called thermocompression bonding.

狹縫視覺151位於吸頭141與基板之間，可判斷吸頭141拾取的晶片的凸塊與基板的接線端子的對齊狀態是否良好。並且，當狹縫視覺151的對齊資訊上出現誤差時，為彌補該誤差，可移動或旋轉吸頭141。 The slit vision 151 is located between the suction head 141 and the substrate, and it can be determined whether the alignment state of the bumps of the wafer picked up by the suction head 141 and the connection terminals of the substrate is good. In addition, when an error occurs in the alignment information of the slit vision 151, to compensate for the error, the suction head 141 may be moved or rotated.

並且，狹縫視覺151可移動至XY平面上的任意位置。例如，狹縫視覺151可沿著設置在上層台150上的第一方向軌道152向X軸方向移動，沿著第二方向軌道153向Y軸方向移動。 In addition, the slit vision 151 can be moved to an arbitrary position on the XY plane. For example, the slit vision 151 may move in the X-axis direction along a first-direction track 152 provided on the upper stage 150 and move in the Y-axis direction along a second-direction track 153.

下面對鍵合拾取器140的操作過程進行詳細說明，鍵合拾取器140移動至打孔裝置170的位置對薄膜148進行穿孔，並移動至片狀塊162的位置，使吸頭141隔著薄膜148吸附晶片的吸附面，然後移動至安裝位置。並且，狹縫視覺151位於基板與吸頭141之間，檢查晶片的對齊狀態。假如，晶片在XY平面上錯位的情況下，可移動吸頭141來彌補誤差，晶片的配置方向以Z軸為中心偏離的情況下，可旋轉吸頭141來彌補誤差。 The operation process of the bond picker 140 is described in detail below. The bond picker 140 moves to the position of the punching device 170 to perforate the film 148 and moves to the position of the sheet block 162, so that the suction head 141 is separated. The film 148 adsorbs the adsorption surface of the wafer, and then moves to the mounting position. In addition, the slit vision 151 is located between the substrate and the suction head 141 to check the alignment state of the wafer. If the wafer is misaligned on the XY plane, the suction head 141 may be moved to compensate for the error, and if the arrangement direction of the wafer is deviated from the Z axis, the suction head 141 may be rotated to compensate for the error.

當晶片對齊完成後，狹縫視覺151移動至不干擾吸頭141下降的位置，吸頭141沿X軸方向下降，並將晶片安裝於基板上。此時，為鍵合晶片，可採用熱壓的方式。即，對晶片加熱的同時進行加壓，使凸塊熔化並在基板上鍵合。完成鍵合後，還可進行利用狹縫視覺151檢查在基板上完成鍵合的半導體晶片的鍵合後檢查(PBI，Post Bonding Inspection)。狹縫視覺151完全不受鍵合拾取器140、龍門架結構及晶片搬運器160結構的影響，因此吸頭141即使在對薄膜148進行打孔作業期間全面地進行PBI，UPH完全不受影響。 After the wafer alignment is completed, the slit vision 151 is moved to a position that does not interfere with the lowering of the suction head 141, the suction head 141 is lowered along the X-axis direction, and the wafer is mounted on the substrate. At this time, it is a bonded wafer, which can be hot-pressed. That is, the wafer is heated and pressurized to melt the bumps and bond them to the substrate. After the bonding is completed, a post-bonding inspection (PBI, Post Bonding Inspection) of the semiconductor wafer on which the bonding is performed on the substrate by the slit vision 151 can also be performed. The slit vision 151 is completely unaffected by the structure of the bond picker 140, the gantry structure, and the wafer carrier 160. Therefore, even if the suction head 141 performs PBI comprehensively during the punching operation of the film 148, UPH is not affected at all.

另一方面，加熱台154可支撐基板。並且，加熱台154可向基板加熱。基板可藉由加熱台154產生的熱而維持規定的溫度範圍。 On the other hand, the heating stage 154 may support the substrate. The heating stage 154 can heat the substrate. The substrate can maintain a predetermined temperature range by the heat generated by the heating stage 154.

未說明的圖式標記有第一糾正標記156、第二糾正標記(未圖示)、溫度感測器158以及測壓元件159。 The unillustrated drawings are labeled with a first correction mark 156, a second correction mark (not shown), a temperature sensor 158, and a load cell 159.

熱壓鍵合裝置100在反復進行鍵合製程的過程中，在對吸頭141和狹縫視覺151的位置進行對齊時會產生誤差。尤其，基於熱壓方式而產生的高熱和向吸頭141施加的壓力，會加快這種誤差的產生。因此，為了使晶片準確地鍵合在基板的安裝位置上，重要的是將吸頭141和狹縫視覺151初始化到預先設定的位置。 In the process of the hot-press bonding apparatus 100 repeating the bonding process, an error occurs when the positions of the suction head 141 and the slit vision 151 are aligned. In particular, the high heat generated by the hot pressing method and the pressure applied to the suction head 141 will accelerate the generation of such errors. Therefore, in order to accurately bond the wafer to the mounting position of the substrate, it is important to initialize the suction head 141 and the slit vision 151 to a predetermined position.

為了糾正鍵合過程中產生的吸頭141和狹縫視覺151的誤差並對齊成初始狀態，吸頭141能夠以第一糾正標記156的資訊為基礎進行初始化，狹縫視覺151能夠以第二糾正標記(未圖示)的信息為基礎進行初始化。並且，利用第一糾正標記156和第二糾正標記(未圖示)進行轉換或更換時，還可用於設置吸頭141和狹縫視覺151。 In order to correct the errors of the suction head 141 and the slit vision 151 generated during the bonding process and align them to the initial state, the suction head 141 can be initialized based on the information of the first correction mark 156, and the slit vision 151 can be corrected by the second correction. Initialization is performed based on the information of a mark (not shown). In addition, when the first correction mark 156 and the second correction mark (not shown) are used for conversion or replacement, the suction head 141 and the slit vision 151 may be provided.

並且，溫度感測器158可測定傳遞至吸頭141的溫度。這是因為吸頭141的溫度高於或低於基準溫度時，會降低鍵合準確度和品質。 In addition, the temperature sensor 158 can measure the temperature transmitted to the tip 141. This is because when the temperature of the suction head 141 is higher or lower than the reference temperature, the bonding accuracy and quality are reduced.

並且，測壓元件159可測定吸頭141施加的壓力。這是因為吸頭141加壓於晶片上的壓力高於或低於基準壓力時，會降低鍵合準確度和品質。 In addition, the load cell 159 can measure the pressure applied by the suction head 141. This is because when the pressure of the suction head 141 pressing on the wafer is higher or lower than the reference pressure, the bonding accuracy and quality are reduced.

另一方面，在晶片藉由熱壓方式鍵合於基板上的過程中，會產生如下問題，即，凸塊藉由鍵合拾取器140施加於晶片的壓力熔化而形成的黏合件沿著晶片側面向上流動並黏附到鍵合拾取器140的底面，或對黏合件加熱期間產生的氣體污染鍵合拾取器140。 On the other hand, in the process of bonding a wafer to a substrate by a hot pressing method, a problem arises in that a bonding member formed by melting a bump by the pressure applied to the wafer by the bonding picker 140 runs along the wafer. The sides flow upward and stick to the bottom surface of the bonding picker 140, or the gas generated during heating of the bonding member contaminates the bonding picker 140.

為此，本發明的一個實施例的熱壓鍵合裝置100可在吸頭141與晶片之間設置薄膜148。此時，為了使吸頭141的真空壓力施加於 晶片上，需要對薄膜148穿孔來形成孔。因此，本發明的一個實施例的熱壓鍵合裝置100還可包括對薄膜148穿孔的打孔裝置170。 To this end, the thermocompression bonding apparatus 100 according to an embodiment of the present invention may include a film 148 between the suction head 141 and the wafer. At this time, in order to apply the vacuum pressure of the suction head 141 to On the wafer, the film 148 needs to be perforated to form holes. Therefore, the thermocompression bonding apparatus 100 according to an embodiment of the present invention may further include a punching device 170 for perforating the film 148.

薄膜148以捲繞在滿滾子(full roller)194上的狀態設置，更可藉由設置在吸頭141兩側的一對導輪193引導，從而捲繞在位於滿滾子194的相反側的空卷軸195上來進行保管。 The film 148 is wound on a full roller 194, and can be guided by a pair of guide wheels 193 provided on both sides of the suction head 141 so as to be wound on the opposite side of the full roller 194. Empty scroll 195 comes up for storage.

並且，滿滾子194、空卷軸195、導輪193以及薄膜卷軸149中的任意一個或多個，可以是藉由薄膜驅動輪196而操作並輸送薄膜148的驅動輪。 In addition, any one or more of the full roller 194, the empty reel 195, the guide wheel 193, and the film reel 149 may be a driving wheel that operates and conveys the film 148 by the film driving wheel 196.

接著，參照第6至8圖，對本發明的一個實施例的打孔裝置170進行說明。 Next, a punching device 170 according to an embodiment of the present invention will be described with reference to FIGS. 6 to 8.

第6圖是表示吸頭141在本發明的一個實施例的打孔裝置170上對薄膜148進行穿孔前的狀態的側視圖，第7圖是第6圖的A區域的放大圖。此外，第8圖是表示吸頭141在打孔裝置170上對薄膜148進行穿孔後的狀態的A區域的放大圖。 FIG. 6 is a side view showing the state of the suction head 141 before perforating the film 148 on the punching device 170 according to an embodiment of the present invention, and FIG. 7 is an enlarged view of the area A in FIG. 6. In addition, FIG. 8 is an enlarged view of an area A showing a state where the film 148 is perforated on the punching device 170 by the suction head 141.

吸附孔174a的底面可設置有吸附晶片的吸附塊174。並且，吸附塊174可形成有向晶片施加真空壓力的吸附孔174a。並且，吸附塊174與吸頭141可拆裝地設置，從而便於更換。 A bottom surface of the suction hole 174a may be provided with a suction block 174 for suctioning a wafer. In addition, the adsorption block 174 may be formed with an adsorption hole 174 a that applies a vacuum pressure to the wafer. In addition, the suction block 174 and the suction head 141 are detachably provided to facilitate replacement.

薄膜148可以以包覆吸附塊174的底部的方式設置。並且，薄膜148兩側具有一對薄膜卷軸149，從而可將薄膜148沿一個方向移動。因此，在鍵合過程中，在薄膜148損壞的情況下，可將損壞的薄膜148移動至一旁，並使新的薄膜148包覆吸附塊174的底部。 The thin film 148 may be provided so as to cover the bottom of the adsorption block 174. In addition, the film 148 has a pair of film reels 149 on both sides, so that the film 148 can be moved in one direction. Therefore, during the bonding process, if the film 148 is damaged, the damaged film 148 can be moved aside, and a new film 148 can be used to cover the bottom of the adsorption block 174.

本發明的一個實施例的打孔裝置170可包括：打孔銷171，設置在晶片搬運器160上，並對薄膜148進行穿孔；保持塊172，在對薄膜148進行穿孔期間，支撐薄膜148底部。另一方面，如圖所示，設置有打孔銷171的基座與晶片搬運器160一體形成。但是，基座與晶片搬運器160也可單獨形成。 A punching device 170 according to an embodiment of the present invention may include: a punching pin 171 disposed on the wafer carrier 160 and perforating the film 148; and a holding block 172 supporting the bottom of the film 148 during perforating the film 148 . On the other hand, as shown in the figure, the base on which the punch pins 171 are provided is formed integrally with the wafer carrier 160. However, the susceptor and the wafer carrier 160 may be formed separately.

打孔銷171可設置多個。並且，打孔銷171可設置在與吸附塊174的吸附孔174a位置對應的位置。並且，打孔銷171的前端部在穿孔過程中被容納於吸附孔174a的內部，此時可具有與吸附孔174a互不干擾的形狀。例如，打孔銷171的前端部可以是越往上走直徑越小的圓錐形狀。 A plurality of punching pins 171 may be provided. In addition, the punching pin 171 may be provided at a position corresponding to the position of the suction hole 174 a of the suction block 174. In addition, the front end portion of the punching pin 171 is accommodated inside the suction hole 174a during the punching process, and may have a shape that does not interfere with the suction hole 174a at this time. For example, the front end portion of the punching pin 171 may have a conical shape with a smaller diameter as it goes upward.

並且，打孔銷171與晶片搬運器160可分離地結合。例如，打孔銷171從晶片搬運器160下方向上插入，此時，可設置成打孔銷171下部凸出的法蘭部171a卡止在晶片搬運器160的底部。並且，可藉由銷固定部件175與晶片搬運器160底部的結合來固定打孔銷171。銷固定部件175可與晶片搬運器160可拆裝地設置，例如，可藉由固定螺栓175a進行連接。 In addition, the punch pin 171 and the wafer carrier 160 are detachably coupled. For example, the punching pin 171 is inserted upward from below the wafer carrier 160. At this time, the flange portion 171a protruding from the lower portion of the punching pin 171 may be locked at the bottom of the wafer carrier 160. In addition, the punching pin 171 can be fixed by the combination of the pin fixing member 175 and the bottom of the wafer carrier 160. The pin fixing member 175 may be detachably provided to the wafer carrier 160, and may be connected by a fixing bolt 175a, for example.

保持塊172可支撐薄膜148的底面。尤其，可支撐由吸附塊174加壓的加壓區域。此外，保持塊172可形成有貫穿打孔銷171的銷容納孔172a。即，打孔銷171在保持塊172內部貫穿銷容納孔172a，對薄膜148進行穿孔。 The holding block 172 may support the bottom surface of the film 148. In particular, a pressurized area pressurized by the adsorption block 174 can be supported. In addition, the retaining block 172 may be formed with a pin receiving hole 172 a penetrating the punching pin 171. That is, the punching pin 171 penetrates the pin accommodating hole 172 a inside the holding block 172 and perforates the film 148.

保持塊172可上下移動。在初始位置上，保持塊172的上表面可高於或等於打孔銷171尖部。並且，保持塊172藉由鍵合拾取器140的加壓而下降時，相對地，打孔銷171上升的同時，對薄膜148進行穿孔。 The holding block 172 is movable up and down. In the initial position, the upper surface of the retaining block 172 may be higher than or equal to the tip of the punching pin 171. In addition, when the holding block 172 is lowered by the pressure of the bonding picker 140, the punching pin 171 is relatively raised, and the film 148 is perforated.

並且，保持塊172可被第一彈性部件176所支撐。第一彈性部件176可設置在保持塊172與晶片搬運器160之間。當無外力施加在保持塊172時，第一彈性部件176向保持塊172施加向上推動的力。並且，鍵合拾取器140向保持塊172加壓時，第一彈性部件176變形，並容許保持塊172向下移動。例如，第一彈性部件176可以是螺旋彈簧，第一彈性部件176下端可容納於在晶片搬運器160上表面凹入的第一彈性部件容納槽176a。 And, the holding block 172 may be supported by the first elastic member 176. The first elastic member 176 may be disposed between the holding block 172 and the wafer carrier 160. When no external force is applied to the holding block 172, the first elastic member 176 applies an upward pushing force to the holding block 172. When the bonding picker 140 presses the holding block 172, the first elastic member 176 is deformed, and the holding block 172 is allowed to move downward. For example, the first elastic member 176 may be a coil spring, and the lower end of the first elastic member 176 may be received in the first elastic member receiving groove 176a recessed on the upper surface of the wafer carrier 160.

並且，晶片搬運器160上可設置有引導保持塊172上下移動的導向部件173。並且，導向部件173可形成有卡止件173a，卡止件173a覆蓋凸出於保持部件的外徑上的法蘭部172b上部。因此，保持塊172不會脫離導向部件173。 In addition, the wafer carrier 160 may be provided with a guide member 173 that guides the holding block 172 to move up and down. In addition, the guide member 173 may be formed with a locking piece 173a covering the upper portion of the flange portion 172b protruding from the outer diameter of the holding member. Therefore, the holding block 172 does not come off the guide member 173.

並且，導向部件173與晶片搬運器160可分離地結合。例如，導向部件173可藉由貫穿晶片搬運器160的固定螺栓173b結合。 The guide member 173 is detachably coupled to the wafer carrier 160. For example, the guide member 173 may be coupled by a fixing bolt 173 b penetrating through the wafer carrier 160.

銷容納孔172a可以以穿孔過程中與上升的打孔銷171互不干擾的方式設置。例如，銷容納孔172a可具有與打孔銷171端部相對應的形狀，銷容納孔172a的內徑大於打孔銷171的外徑。 The pin receiving hole 172a may be provided in a manner that does not interfere with the rising punch pin 171 during the punching process. For example, the pin receiving hole 172 a may have a shape corresponding to the end of the punching pin 171, and the inner diameter of the pin receiving hole 172 a is larger than the outer diameter of the punching pin 171.

另一方面，打孔銷171在對薄膜148進行穿孔的過程中，薄膜148的穿孔周邊形成有朝上的毛刺(burr)。假如，在沒有支撐薄膜148底面的保持塊172，或銷容納孔172a的大小比打孔銷171的外徑大很 多的情況下，在打孔銷171下降的過程中毛刺會沿著打孔銷171向下移動並朝下。如上，薄膜148的毛刺朝下時，即使向吸頭141施加真空壓力，晶片也不會與薄膜148緊貼，且不會水平配置。這會在基板上鍵合晶片的過程中引起誤差。 On the other hand, when the punching pin 171 perforates the film 148, a burr is formed on the periphery of the perforation of the film 148 to face upward. If the holding block 172 without the supporting film 148 bottom surface, or the pin receiving hole 172a is larger than the outer diameter of the punching pin 171, In many cases, the burr will move downward along the punching pin 171 and downward when the punching pin 171 is lowered. As described above, when the burr of the film 148 is facing downward, even if a vacuum pressure is applied to the suction head 141, the wafer will not be in close contact with the film 148, and it will not be arranged horizontally. This can cause errors in the process of bonding the wafers to the substrate.

但是，參照第9圖可知，本發明的實施例的打孔裝置170中的薄膜148的毛刺會向薄膜148的穿孔上方突出。第9圖是表示打孔銷171下降的狀態下的毛刺形狀的放大圖。 However, referring to FIG. 9, it can be seen that the burr of the film 148 in the punching device 170 according to the embodiment of the present invention protrudes above the perforation of the film 148. FIG. 9 is an enlarged view showing a burr shape in a state where the punching pin 171 is lowered.

形成於保持塊172上表面的銷容納孔172a的內徑，相比打孔銷171上升至最高位置時與保持塊172的上表面位於同一平面時的打孔銷171的外徑大一點。 The inner diameter of the pin receiving hole 172a formed on the upper surface of the holding block 172 is larger than the outer diameter of the punching pin 171 when the punching pin 171 is raised to the highest position and the upper surface of the holding block 172 is on the same plane.

並且，形成在保持塊172上表面的銷容納孔172a的內徑可小於或等於形成在吸附塊174下表面的吸附孔174a的內徑。形成毛刺的區域的最大尺寸不應超過吸附孔174a的內徑。因此，銷容納孔172a內徑小於或等於毛刺形成區域的最大尺寸時，可防止打孔銷171下降時薄膜148的毛刺沿著打孔銷171進入到銷容納孔172a內部。 Also, the inner diameter of the pin receiving hole 172 a formed on the upper surface of the holding block 172 may be smaller than or equal to the inner diameter of the adsorption hole 174 a formed on the lower surface of the adsorption block 174. The maximum size of the burr-forming region should not exceed the inner diameter of the suction hole 174a. Therefore, when the inner diameter of the pin receiving hole 172 a is smaller than or equal to the maximum size of the burr formation area, the burr of the film 148 can be prevented from entering the pin receiving hole 172 a along the punch pin 171 when the punch pin 171 is lowered.

接著，參照第10圖和第11圖，對本發明的另一個實施例的打孔裝置170-1進行說明。 Next, a punching device 170-1 according to another embodiment of the present invention will be described with reference to Figs. 10 and 11.

第10圖是表示吸頭141在本發明的另一個實施例的打孔裝置170-1上對薄膜148進行穿孔後的狀態的側視圖，第11圖是第10圖的B區域的放大圖。 FIG. 10 is a side view showing a state where the suction head 141 perforates the film 148 on the punching device 170-1 according to another embodiment of the present invention, and FIG. 11 is an enlarged view of a region B in FIG. 10.

本發明的另一個實施例的打孔裝置170-1中的打孔銷171可上下移動。此時，打孔銷171以只有在規定壓力下才會向下移動的方式 設置，從而在打孔銷171對薄膜148進行穿孔的過程中，打孔銷171不會向下移動。 The punching pin 171 in the punching device 170-1 of another embodiment of the present invention can be moved up and down. At this time, the punching pin 171 moves downward only under a predetermined pressure. It is arranged so that the punching pin 171 does not move downward during the punching of the film 148 by the punching pin 171.

並且，打孔銷171可由第二彈性部件177支撐。第二彈性部件177可設置在打孔銷171與銷固定部件175之間。在沒有向打孔銷171施加規定大小以上的壓力時，第二彈性部件177對打孔銷171施加向上推動的力。並且，在施加規定大小以上的壓力時，第二彈性部件177變形，並容許打孔銷171向下移動。例如，第二彈性部件177可以是螺旋彈簧，第二彈性部件177的上端被打孔銷171下部的法蘭部171a支撐，第二彈性部件177的下端被銷固定部件175支撐。 And, the punching pin 171 may be supported by the second elastic member 177. The second elastic member 177 may be disposed between the punching pin 171 and the pin fixing member 175. When the punching pin 171 is not pressed with a predetermined magnitude or more, the second elastic member 177 applies a pushing force to the punching pin 171 upward. In addition, when a pressure of a predetermined magnitude or more is applied, the second elastic member 177 is deformed, and the punching pin 171 is allowed to move downward. For example, the second elastic member 177 may be a coil spring. The upper end of the second elastic member 177 is supported by the flange portion 171 a at the lower portion of the punch pin 171, and the lower end of the second elastic member 177 is supported by the pin fixing member 175.

第12圖是表示吸頭141不重合(misalign)時的B區域的放大圖。 FIG. 12 is an enlarged view showing a region B when the tips 141 are misaligned.

參照第12圖，打孔銷171以吸頭141不重合時向下移動的方式設置，從而能夠防止吸頭141或打孔銷171破損。 12, the punching pin 171 is provided so as to move downward when the tip 141 is not overlapped, so that the tip 141 or the punching pin 171 can be prevented from being damaged.

為此，第二彈性部件177的彈性係數可選為，穿孔過程中，在薄膜148對打孔銷171施加的壓力下不產生彈性變形，但在比其大的壓力下開始變形。 For this reason, the elastic coefficient of the second elastic member 177 may be selected as follows: during the punching process, the elastic deformation does not occur under the pressure exerted by the film 148 on the punching pin 171, but it begins to deform under a pressure greater than that.

即，第二彈性部件177在保持塊172受到吸頭141的加壓而下降的同時在薄膜148向打孔銷171施加的壓力範圍內不變形，因此，打孔銷171不會向下移動，從而能夠對薄膜148進行穿孔。但是，當受到比上述壓力更大壓力的情況下，例如，不重合的吸頭141向打孔銷171加壓時，第二彈性部件177變形，打孔銷171向下移動。 That is, the second elastic member 177 does not deform within the pressure range applied by the film 148 to the punching pin 171 while the holding block 172 is lowered by the pressure of the suction head 141, and therefore, the punching pin 171 does not move downward. Thereby, the film 148 can be perforated. However, when the pressure is greater than the above pressure, for example, when the non-overlapping suction head 141 presses the punching pin 171, the second elastic member 177 deforms and the punching pin 171 moves downward.

在第4圖的描述中已說明了晶片搬運器160的片狀塊162的一側，可並排配置有打孔裝置170，打孔裝置170用於對被吸附在吸頭141的薄膜148打孔。並且，晶片搬運器160可藉由搬運機器人161沿Y軸方向移動。 In the description of FIG. 4, it has been explained that one side of the sheet block 162 of the wafer carrier 160 may be provided with a punching device 170 side by side. The punching device 170 is used for punching the film 148 adsorbed on the suction head 141. . In addition, the wafer carrier 160 can be moved in the Y-axis direction by the transport robot 161.

並且，在第12圖的描述中已說明了為了防止不重合的情況，吸頭141需要在打孔裝置170上形成的銷容納孔172a的位置與吸附孔174a的位置對齊的狀態下對薄膜148進行穿孔。這是因為，如果吸頭141在與打孔裝置170的銷容納孔172a偏離配置的狀態下，利用打孔銷171對薄膜148進行穿孔，則會產生如第12圖所示的打孔銷171或吸附塊174破損的問題。 In addition, it has been described in the description of FIG. 12 that in order to prevent misalignment, the suction head 141 needs to align the film 148 with the position of the pin receiving hole 172a formed in the punching device 170 aligned with the position of the suction hole 174a. Perform perforation. This is because if the suction head 141 is deviated from the pin accommodation hole 172 a of the punching device 170 and the film 148 is perforated by the punching pin 171, the punching pin 171 shown in FIG. 12 is generated. Or the adsorption block 174 is broken.

因此，為了使打孔裝置170對吸附於吸頭141的薄膜148的正確位置進行穿孔，需進行對齊吸頭141與打孔裝置170的相對位置的校準作業。 Therefore, in order for the punching device 170 to perforate the correct position of the film 148 adsorbed on the suction head 141, a calibration operation for aligning the relative positions of the suction head 141 and the punching device 170 needs to be performed.

為了進行吸頭141與打孔裝置170的校準作業，本發明的一個實施例中，並沒有分別設置檢測吸頭141位置的視覺相機和檢測打孔裝置170位置的視覺相機，而是利用一個上視視覺155，進行糾正吸頭141和打孔裝置170的相對位置以使其對齊的作業。只是，本發明中僅利用了一個上視視覺155，因此在晶片搬運器160下面設置了作為檢測打孔裝置170位置的基準的糾正部。例如，糾正部作為基準點(fiducials)，可包括形成於片狀塊162下部的孔或糾正標記。 In order to perform the calibration of the suction head 141 and the punching device 170, in one embodiment of the present invention, a visual camera for detecting the position of the suction head 141 and a visual camera for detecting the position of the punching device 170 are not separately provided. The vision 155 corrects the relative positions of the suction head 141 and the punching device 170 to align them. However, since only one top-view vision 155 is used in the present invention, a correction section serving as a reference for detecting the position of the punching device 170 is provided under the wafer carrier 160. For example, the correction section may serve as fiducials, and may include a hole or a correction mark formed in the lower portion of the sheet-like block 162.

值得注意的是，糾正並對齊相對位置的作業可藉由以下步驟進行，即，片狀塊162和吸頭以預先設定的距離移動並位於上視視覺155 的上部時，上視視覺155分別檢測基準點的中心位置和吸頭的中心位置，並求出其偏移值後，在與片狀塊162隔開設定值的距離的打孔裝置的位置值上反應偏移值的大小，並將片狀塊162向Y軸方向移動相當於上述反應值的距離，以使吸頭的中心位置和打孔裝置的中心位置對齊。 It is worth noting that the operation of correcting and aligning the relative position can be performed by the following steps, that is, the sheet-shaped block 162 and the suction head move at a predetermined distance and are located in the upward vision 155 In the upper part, the top vision 155 detects the center position of the reference point and the center position of the suction head, and obtains the offset value, and then positions the position of the punching device at a set distance from the sheet block 162. Up the magnitude of the response offset value, and move the sheet-like block 162 in the Y-axis direction by a distance corresponding to the above-mentioned response value, so that the center position of the tip is aligned with the center position of the punching device.

雖在圖中未示出，本發明的另一個實施例中，晶片搬運器160的打孔裝置170和片狀塊162的位置可互換。即，可以以上視視覺155為中心，在鄰近上視視覺155的內側可設置打孔裝置，在離上視視覺155較遠的一側設置片狀塊162。此類情況下，也可按同樣的順序向片狀塊162裝載半導體晶片，且吸頭對薄膜進行穿孔後，拾取片狀塊162上的半導體晶片。即，晶片搬運器向單元拾取器130方向的Y軸方向輸送時，單元拾取器130將半導體晶片放置於片狀塊162上，然後，晶片搬運器沿Y軸方向輸送後，將打孔裝置設置在吸頭的下部並對薄膜進行穿孔後，晶片搬運器重新沿Y軸方向輸送規定距離並輸送至吸頭的下部，吸附片狀塊162上裝載的半導體晶片後，進行熱壓鍵合。 Although not shown in the drawings, in another embodiment of the present invention, the positions of the punching device 170 and the sheet block 162 of the wafer carrier 160 are interchangeable. That is, the upper-view vision 155 may be the center, a punching device may be provided on the inner side adjacent to the upper-view vision 155, and a sheet-like block 162 is provided on the side farther from the upper-view vision 155. In such a case, a semiconductor wafer may be loaded on the sheet-like block 162 in the same order, and after the film is perforated by the suction head, the semiconductor wafer on the sheet-like block 162 may be picked up. That is, when the wafer carrier is transported in the Y-axis direction of the unit picker 130, the unit picker 130 places the semiconductor wafer on the sheet block 162, and after the wafer carrier is transported in the Y-axis direction, the punching device is set After perforating the film at the lower part of the suction head, the wafer carrier again conveys a predetermined distance in the Y-axis direction to the lower part of the suction head, sucks the semiconductor wafer loaded on the sheet block 162, and performs thermocompression bonding.

但是，本發明中，執行同一行上的鍵合作業期間，吸頭只沿X軸方向移動，晶片搬運器負責Y軸方向的移動，從而能夠減少移動較大的龍門架的X軸方向的移動，因此對設備內的振動也幾乎沒有影響。 However, in the present invention, during the execution of the keying operation on the same line, the tip moves only in the X-axis direction, and the wafer carrier is responsible for the movement in the Y-axis direction, thereby reducing the movement in the X-axis direction of the larger gantry. , So it has almost no effect on the vibration inside the device.

第13圖是表示本發明的一個實施例的薄膜隔離裝置190的圖。 FIG. 13 is a diagram showing a thin film isolation device 190 according to an embodiment of the present invention.

打孔裝置170經過對薄膜148進行打孔的一系列製程，並實現半導體晶片熱壓鍵合在基板上後，為下一個半導體晶片的作業，會 重複此前進行的相同作業。為此，完成打孔的薄膜148藉由薄膜卷軸149捲繞回收，並將新的薄膜148設置在吸頭141下部以待位。 The punching device 170 undergoes a series of processes for punching the thin film 148 and realizes the semiconductor wafer thermal compression bonding on the substrate, and is the next semiconductor wafer operation. Repeat the same operation as before. To this end, the perforated film 148 is wound and recovered by a film reel 149, and a new film 148 is set at the lower part of the suction head 141 to be in position.

然而，在熱壓時會發生薄膜148因熱而熔化，並黏附於吸頭141上的問題。為了解決這種問題，本發明的一個實施例中的鍵合拾取器140可利用薄膜隔離裝置190將薄膜148推離，以隔離貼在吸頭141上的薄膜148。 However, a problem that the film 148 melts due to heat and adheres to the suction head 141 during hot pressing occurs. To solve this problem, the bonding picker 140 in an embodiment of the present invention can push the film 148 away by using the film isolating device 190 to isolate the film 148 attached to the suction head 141.

薄膜隔離裝置190可包括推離薄膜148的薄膜隔離滾輪191和與薄膜隔離滾輪191相連並且上下可移動的滾輪輸送裝置192。 The film isolation device 190 may include a film isolation roller 191 that pushes away the film 148 and a roller conveying device 192 connected to the film isolation roller 191 and movable up and down.

薄膜隔離滾輪191設置為可旋轉的滾輪形狀，從而在推離薄膜148的過程中，可將對薄膜148的損壞最小化。並且，與薄膜隔離滾輪191相連接的滾輪輸送裝置192可將薄膜隔離滾輪191沿上下方向移動，例如可以是缸體。 The film isolation roller 191 is provided in a rotatable roller shape, so that damage to the film 148 can be minimized during the process of pushing away from the film 148. In addition, the roller conveying device 192 connected to the film isolation roller 191 can move the film isolation roller 191 in the vertical direction, and may be, for example, a cylinder.

薄膜隔離裝置190可位於吸頭141的一側，可設置在吸頭141兩側的薄膜卷軸149中任意一個與吸頭141之間。 The film isolation device 190 may be located on one side of the suction head 141 and may be disposed between any one of the film reels 149 on both sides of the suction head 141 and the suction head 141.

第14圖是表示本發明的另一個實施例的薄膜隔離裝置190-1的圖。 FIG. 14 is a diagram showing a thin film isolation device 190-1 according to another embodiment of the present invention.

參照第14圖，薄膜隔離裝置190-1可位於吸頭141的兩側，可分別設置在吸頭141兩側的薄膜卷軸149與吸頭141之間。 Referring to FIG. 14, the film isolation device 190-1 may be located on both sides of the suction head 141, and may be respectively disposed between the film reel 149 and the suction head 141 on both sides of the suction head 141.

此時，一對薄膜隔離裝置190-1可同時驅動或相對地驅動。例如，當僅靠某一個薄膜隔離裝置190-1的操作，薄膜148不易從吸頭141隔離時，可操作另一個薄膜隔離裝置190-1。 At this time, the pair of thin film isolation devices 190-1 may be driven simultaneously or relatively. For example, when the film 148 is not easily separated from the suction head 141 by the operation of only one film isolation device 190-1, another film isolation device 190-1 may be operated.

接著，參照第15圖和第16圖，對本發明的一個實施例的輪圈單元180進行說明。 Next, a rim unit 180 according to an embodiment of the present invention will be described with reference to FIGS. 15 and 16.

The rim unit 180 may include a glass holder 182 to correct the deviation of the slit vision 151 and a glass holder 181 provided on the upper stage 150 and supporting the glass holder 182.

例如，玻璃保持器182可利用多個螺栓等來安裝在玻璃支架181上。並且，貫穿螺栓的玻璃保持器182的結合孔182b可設置成向上下方向延伸的長孔形狀。因此，玻璃保持器182可以以沿上下方向可細微調節位置的方式安裝在支架181上。 For example, the glass holder 182 may be mounted on the glass holder 181 using a plurality of bolts or the like. In addition, the coupling hole 182b of the glass holder 182 passing through the bolt may be provided in a long hole shape extending in the up-down direction. Therefore, the glass holder 182 can be mounted on the bracket 181 so that the position can be finely adjusted in the up-down direction.

玻璃保持器182可設定為“”形狀，狹縫視覺151位於於上部保持器與下部保持器之間的空間。 The glass holder 182 can be set to " Shape, the slit vision 151 is located in the space between the upper holder and the lower holder.

The slit vision 151 located on the upper and lower coaxial lines can be checked at the same time, and the fiducial mark of the upper glass 183 and the lower glass 184 can be detected, so that the deviation of the slit vision 151 can be determined.

並且，上部玻璃183可在固定於上部玻璃保持器185上的狀態下設置在玻璃保持器182的上部保持器上。並且，下部玻璃184可在固定於下部玻璃保持器186上的狀態下，設置在玻璃保持器182的下部保持器上。 The upper glass 183 may be provided on the upper holder of the glass holder 182 in a state of being fixed to the upper glass holder 185. The lower glass 184 may be provided on the lower holder of the glass holder 182 in a state of being fixed to the lower glass holder 186.

並且，上部玻璃保持器185，可沿設在玻璃保持器182的上部保持器上的導軌182a，在上部保持器上進行上下方向上的細微的位置調整。同理，下部玻璃保持器186，可沿設在玻璃保持器182的下部保持器上的導軌182a，在下部保持器上進行上下方向上的細微的位置調整。 In addition, the upper glass holder 185 can perform fine position adjustment in the vertical direction on the upper holder along the guide rail 182a provided on the upper holder of the glass holder 182. Similarly, the lower glass holder 186 can be finely adjusted in the vertical direction on the lower holder along the guide rail 182a provided on the lower holder of the glass holder 182.

The first adjusting block 187 can finely adjust the position of the glass holder 182 in the vertical direction while being fixed on the glass holder 181.

並且，輪圈單元180可包括第二調整塊188，以便精確調整上部玻璃保持器185設置在玻璃保持器182上部保持器上的位置。第二 調整塊188可在固定於玻璃保持器182上部保持器上的狀態下，微調上部玻璃保持器185的上下方向位置。 Also, the rim unit 180 may include a second adjustment block 188 so as to accurately adjust a position where the upper glass holder 185 is disposed on the upper holder of the glass holder 182. second The adjustment block 188 can finely adjust the position of the upper glass holder 185 in the vertical direction while being fixed to the upper holder of the glass holder 182.

參照第16圖，狹縫視覺151可在“”形狀的玻璃保持器182的內部空間移動，設定在狹縫視覺151上部的視覺晶片檢查形成有基準點標記的上部玻璃183，位於狹縫視覺151下部的視覺基板檢查形成有基準點標記的下部玻璃184，從而可檢查狹縫視覺151的偏移。 Referring to FIG. 16, the slit vision 151 can be The internal space of the "shaped glass holder 182 moves, and the visual wafer set on the upper part of the slit vision 151 inspects the upper glass 183 formed with the reference point mark, and the visual substrate located on the lower part of the slit vision 151 inspects the lower portion formed with the reference point mark. The glass 184 makes it possible to check the deviation of the slit vision 151.

並且，輪圈單元180可用幾乎無熱變形的剛性鋼鐵或玻璃材料製作，上部玻璃183和下部玻璃184可使用幾乎無熱變形的玻璃材料。 In addition, the rim unit 180 can be made of rigid steel or glass material with almost no thermal deformation, and the upper glass 183 and the lower glass 184 can use glass material with almost no thermal deformation.

狹縫視覺151是可移動的同軸視覺，可將根據用作晶片校正夾具的上部玻璃183和用作基板校正夾具的下部玻璃184的檢查結果獲得的位置設為基準位置。 The slit vision 151 is movable coaxial vision, and a position obtained from the inspection results of the upper glass 183 serving as a wafer correction jig and the lower glass 184 serving as a substrate correction jig can be set as a reference position.

並且，在半導體晶片鍵合在基板上之前，狹縫視覺151可藉由輪圈單元180確認視覺晶片和視覺基板的誤差並進行補償。並且，在輪圈單元180區域狹縫視覺151週期性檢查上部玻璃183和下部玻璃184的基準點標記，從而可檢測出基於熱變形的誤差。並且，支撐狹縫視覺151的上層台150可藉由加熱器或加熱台150受熱，狹縫視覺151發生變形，因此，可利用輪圈單元180定期確認是否變形並進行補償，以保證準確性。這種狹縫視覺的誤差檢查，不影響吸頭141的驅動，因此，在作業過程中可定期地或隨時確認並進行補償。 In addition, before the semiconductor wafer is bonded to the substrate, the slit vision 151 can confirm and compensate the error between the vision wafer and the vision substrate by the rim unit 180. In addition, the slit vision 151 in the rim unit 180 region periodically checks the reference point marks of the upper glass 183 and the lower glass 184, so that errors due to thermal deformation can be detected. In addition, the upper stage 150 supporting the slit vision 151 can be heated by the heater or the heating stage 150, and the slit vision 151 is deformed. Therefore, the rim unit 180 can be periodically used to confirm whether the deformation is caused and compensated to ensure accuracy. This slit vision error check does not affect the driving of the suction head 141, and therefore, it can be confirmed and compensated periodically or at any time during the operation.

更詳細地，狹縫視覺在吸頭141吸附的半導體晶片與鍵合半導體晶片的基板之間檢查半導體晶片的對齊狀態後，移動至輪圈單元檢查狹縫視覺的視覺晶片和視覺基板的誤差值，在有偏移的情況下，檢 查下一個半導體晶片和鍵合半導體晶片的基板的對齊狀態，並在補償吸頭141的移動量時，能反應誤差值。每搬運一個半導體晶片時，均可反應誤差值，從而能夠確保精度，並在設備內不會與其他組成部分重疊或相互影響，因此，即使隨時檢查視覺狹縫視覺的誤差，也完全不會降低設備內的UPH。 In more detail, the slit vision checks the alignment state of the semiconductor wafer between the semiconductor wafer sucked by the suction head 141 and the substrate to which the semiconductor wafer is bonded, and then moves to the rim unit to check the error value of the vision wafer and the vision substrate of the slit vision. In the case of offset, check The alignment state of the next semiconductor wafer and the substrate to which the semiconductor wafer is bonded is checked, and an error value can be reflected when the movement amount of the tip 141 is compensated. The error value can be reflected every time a semiconductor wafer is transported, so that accuracy can be ensured, and it does not overlap with or affect other components in the device. Therefore, even if the visual slit error is checked at any time, it will not be reduced. UPH inside the device.

並且，在吸頭141吸附的半導體晶片熱壓鍵合在置於加熱台154上的基板上之前，可使用狹縫視覺進行151檢查，並比較獲取的值，來補償吸頭141的移動量。 In addition, before the semiconductor wafer sucked by the suction head 141 is thermally bonded to the substrate placed on the heating stage 154, the inspection of the 151 can be performed using slit vision, and the obtained values can be compared to compensate the movement amount of the suction head 141.

第18圖表示第二晶片搬運器160-2從單元拾取器130接收半導體晶片並移動至第二鍵合拾取器140-2的作業區域，第一晶片搬運器160-2等候從單元拾取器130接收新的半導體晶片的狀態的圖。 FIG. 18 shows that the second wafer carrier 160-2 receives the semiconductor wafer from the unit picker 130 and moves to the work area of the second bond picker 140-2. The first wafer carrier 160-2 waits for the unit picker 130 A diagram of the state of receiving a new semiconductor wafer.

此時，鍵合拾取器從晶片搬運器接收半導體晶片時，可沿X軸和Y軸方向移動的鍵合拾取器，只沿著X方向移動，晶片搬運器可沿Y軸方向移動，從而能夠與鍵合拾取器的作業區域並排在同一行，因此，能夠使藉由龍門架移動的鍵合拾取器的Y軸移動最小化，以減少振動的發生。 At this time, when the bond picker receives the semiconductor wafer from the wafer carrier, the bond picker that can move in the X-axis and Y-axis directions moves only in the X-direction, and the wafer carrier can move in the Y-axis direction, so that It is on the same line as the working area of the bond picker. Therefore, the Y-axis movement of the bond picker moved by the gantry can be minimized to reduce the occurrence of vibration.

更詳細地，鍵合拾取器在X軸對同一行執行鍵合作業期間，鍵合拾取器僅在X軸移動，而沒有向Y軸移動，並將晶片搬運器沿Y軸移動至與鍵合拾取器X軸線相同的行列，從而使晶片搬運器的打孔部位 於吸頭141的下部。隨後，用打孔裝置對吸頭141吸附的薄膜穿孔後，晶片搬運器重新沿Y軸方向移動，使片狀塊162位於吸頭141的下部。因此，鍵合拾取器無需沿Y軸移動，即可從晶片搬運器接收薄膜穿孔後的半導體晶片。並且，只需在基板的行列切換時最初將鍵合拾取器沿Y軸方向輸送一次，因此，可將鍵合拾取器的Y軸移動最小化。 In more detail, during the execution of the bonding picker on the same row on the X-axis, the bonding picker only moves on the X-axis, but does not move to the Y-axis, and moves the wafer carrier along the Y-axis to the bonding The same rows and columns of the X axis of the picker, so that the punched portion of the wafer carrier On the lower part of the suction head 141. Subsequently, after the film adsorbed by the suction head 141 is perforated with a punching device, the wafer carrier is moved again in the Y-axis direction, so that the sheet-shaped block 162 is located at the lower portion of the suction head 141. Therefore, the bond picker does not need to move along the Y-axis to receive the semiconductor wafer after the film perforation from the wafer carrier. Furthermore, it is only necessary to firstly transport the bonding picker along the Y-axis direction when switching the ranks of the substrates, so that the Y-axis movement of the bonding picker can be minimized.

另一方面，本發明中鍵合拾取器和晶片搬運器分別設有多個，鍵合拾取器可藉由在X-Y平面上能夠移動至任意位置的龍門架來輸送，並在X軸方向上相互對稱。晶片搬運器的數量與鍵合拾取器數量對應。並且，這些第一鍵合拾取器、第二鍵合拾取器、第一晶片搬運器、第二晶片搬運器可藉由下述動作驅動。 On the other hand, in the present invention, a plurality of bond pickers and wafer carriers are provided respectively, and the bond pickers can be transported by a gantry that can be moved to any position on the XY plane, and mutually move in the X axis direction. symmetry. The number of wafer carriers corresponds to the number of bond pickers. The first bond picker, the second bond picker, the first wafer carrier, and the second wafer carrier can be driven by the following operations.

第一晶片搬運器160-1將半導體晶片傳遞至第一鍵合拾取器，半導體晶片置於晶片搬運器後，在鍵合拾取器的吸頭141用第一打孔裝置對薄膜進行穿孔後吸附片狀塊162上的半導體晶片期間，第二晶片搬運器160-2從單元拾取器130接收新的半導體晶片之後，為將半導體晶片傳遞至第二鍵合拾取器一側而將第二晶片搬運器160-2沿Y軸方向移動的期間，完成作業的第一晶片搬運器160-1沿Y軸移動，以便從單元拾取器130接收新的半導體晶片，並相互依次反復進行這種操作。 The first wafer carrier 160-1 transfers the semiconductor wafer to the first bonding picker. After the semiconductor wafer is placed in the wafer carrier, the suction head 141 of the bonding picker uses the first punching device to perforate the film and adsorbs the film. During the semiconductor wafer on the chip block 162, after the second wafer carrier 160-2 receives a new semiconductor wafer from the unit picker 130, the second wafer carrier 160-2 transfers the second wafer to the side of the second bonding picker to transfer the semiconductor wafer While the shifter 160-2 is moving in the Y-axis direction, the first wafer carrier 160-1 that has completed the job is shifted in the Y-axis so as to receive new semiconductor wafers from the unit picker 130 and repeat this operation one after another.

另一方面，在對齊打孔裝置170和吸頭141的位置的狀態下，對吸頭141吸附的薄膜148進行穿孔後，鍵合拾取器向一個方向移動，並拾取片狀塊162上裝載的半導體晶片，移動至加熱台154，以向半導體晶片施加熱和壓力，並鍵合半導體晶片和基板。 On the other hand, in a state where the positions of the punching device 170 and the suction head 141 are aligned, after perforating the film 148 adsorbed by the suction head 141, the bond picker moves in one direction and picks up the sheet-shaped block 162. The semiconductor wafer is moved to the heating stage 154 to apply heat and pressure to the semiconductor wafer and bond the semiconductor wafer and the substrate.

上述第11圖和第12圖中說明了，為了利用一個上視視覺155對本發明中吸頭141吸附的薄膜148的準確位置進行穿孔，需要進行校正吸頭141和打孔裝置170的相對位置的作業的內容，對此，下面將參照第19至23圖進行更詳細的說明。 The above figures 11 and 12 illustrate that in order to perforate the exact position of the film 148 adsorbed by the suction head 141 in the present invention using a top-view vision 155, it is necessary to correct the relative positions of the suction head 141 and the punching device 170. The content of the operation will be described in more detail below with reference to FIGS. 19 to 23.

上視視覺155位於晶片搬運器160的Y軸方向上。晶片搬運器160可藉由搬運機器人161向Y軸方向移動，並移動至上視視覺155所處的位置，上視視覺155可確認晶片搬運器160上的基準點資訊。 The top view 155 is located in the Y-axis direction of the wafer carrier 160. The wafer handler 160 can be moved in the Y-axis direction by the transfer robot 161 and moved to the position where the top-view vision 155 is located. The top-view vision 155 can confirm the reference point information on the wafer handler 160.

為了使上視視覺155能夠確認晶片搬運器160的位置，在晶片搬運器160的下面形成用於檢測晶片搬運器160位置的基準點標記尤為重要。 In order for the top-view vision 155 to confirm the position of the wafer carrier 160, it is particularly important to form a reference point mark under the wafer carrier 160 for detecting the position of the wafer carrier 160.

為此，包含基準點的校正部可以以黏附到晶片搬運器160的下面或形成於片狀塊162下部面的基準孔164的形態設置。將校正部黏附與片狀塊162上的過程中，會發生位置值偏離的情況，因此，可藉由設置與片狀塊162一體形成的基準孔164來排除這種變數，因此，較佳在片狀塊162的下部面設置基準孔164。 For this purpose, the correction portion including the reference point may be provided in the form of a reference hole 164 adhered to the lower surface of the wafer carrier 160 or formed on the lower surface of the sheet block 162. During the process of adhering the correction part to the sheet-like block 162, the position value may deviate. Therefore, the reference hole 164 integrally formed with the sheet-like block 162 can be used to eliminate such variables. Therefore, it is preferable to A reference hole 164 is provided on a lower surface of the sheet-like block 162.

此時，基準孔164更可以上下貫穿片狀塊162的方式形成。 At this time, the reference hole 164 may be formed so as to penetrate the sheet-like block 162 up and down.

上視視覺155可檢查形成於晶片搬運器160下面的基準孔164，並藉由有關基準孔164和打孔裝置170間距的資訊檢測打孔裝置170的位置。 The top-view vision 155 can check the reference hole 164 formed under the wafer carrier 160 and detect the position of the punching device 170 based on the information about the distance between the reference hole 164 and the punching device 170.

第19圖是表示吸頭141為了對薄膜148進行穿孔而位於打孔裝置170上部的狀態的圖。 FIG. 19 is a diagram showing a state where the suction head 141 is positioned at an upper portion of the punching device 170 in order to perforate the film 148.

具備打孔裝置170的晶片搬運器160藉由搬運機器人161沿Y軸方向移動至鍵合拾取器140的吸頭141所處的區域，鍵合拾取器140沿X軸方向移動至晶片搬運器160的打孔裝置170所處的區域。 The wafer handler 160 including the punching device 170 is moved by the transfer robot 161 in the Y-axis direction to the region where the suction head 141 of the bond picker 140 is located, and the bond picker 140 is moved to the wafer handler 160 in the X-axis direction. The area where the punching device 170 is located.

更詳細地，與晶片搬運器160相連接並支撐晶片搬運器160的搬運機器人161，可連接於搬運器輸送部件165，且搬運器輸送部件165可藉由搬運器輸送馬達166而運作。 In more detail, the transfer robot 161 connected to the wafer handler 160 and supporting the wafer handler 160 may be connected to the handler transfer member 165, and the handler transfer member 165 may be operated by the handler transfer motor 166.

例如，搬運器輸送部件165可以是螺絲釘，可藉由傳送帶與搬運器輸送馬達166連接。並且，搬運機器人161包括與搬運器輸送部件165結合的螺紋部件，可藉由搬運器輸送部件165的旋轉運動進行直線往復運動。 For example, the carrier conveying member 165 may be a screw and may be connected to the carrier conveying motor 166 by a conveyor belt. In addition, the transfer robot 161 includes a threaded member coupled to the transfer member 165 and can perform a linear reciprocating motion by the rotary movement of the transfer member 165.

即，搬運器輸送馬達166的驅動力傳遞至搬運器輸送部件165以旋轉搬運器輸送部件165，當搬運器輸送部件165向一個方向旋轉時，將與搬運器輸送部件165螺紋結合的搬運機器人161向Y軸上的一個方向移動。相反，搬運器輸送部件165反方向旋轉時，搬運機器人161向Y軸上的反方向移動。 That is, the driving force of the carrier conveying motor 166 is transmitted to the carrier conveying member 165 to rotate the carrier conveying member 165, and when the carrier conveying member 165 rotates in one direction, the conveying robot 161 screwed to the carrier conveying member 165 is screwed Move in one direction on the Y axis. Conversely, when the carrier conveying member 165 rotates in the reverse direction, the transport robot 161 moves in the reverse direction on the Y axis.

並且，搬運機器人161可沿向Y軸方向設置的載體輸送軌道167移動。 In addition, the transfer robot 161 can move along a carrier transfer rail 167 provided in the Y-axis direction.

第20圖是表示吸頭141對薄膜148進行穿孔後位於片狀塊162上部的狀態的圖。 FIG. 20 is a view showing a state where the suction head 141 perforates the film 148 and is located on the upper portion of the sheet-like block 162.

晶片搬運器160可沿Y軸方向移動，以使吸頭141位於片狀塊162的上部。此時，晶片搬運器160可向Y軸方向移動預先儲存的、相 當於片狀塊162和打孔裝置170之間的距離。因此，無需移動鍵合拾取器140，也能夠對齊吸頭141和片狀塊162. The wafer carrier 160 can be moved in the Y-axis direction so that the suction head 141 is positioned on the upper portion of the sheet block 162. At this time, the wafer carrier 160 can move the pre-stored It depends on the distance between the sheet-like block 162 and the punching device 170. Therefore, without moving the bonding picker 140, it is also possible to align the suction head 141 and the sheet-like block 162.

第21至23圖是表示為了使打孔裝置170在吸頭141的準確位置上對薄膜148進行穿孔的校正方法。下面將藉由圖式對對齊吸頭141和打孔裝置170的中心位置的過程進行說明。 21 to 23 are diagrams illustrating a method of correcting the perforation of the film 148 in order to make the punching device 170 at the exact position of the suction head 141. The process of aligning the center positions of the suction head 141 and the punching device 170 will be described below with reference to the drawings.

第21圖表示上視視覺155檢測吸頭141的中心位置的狀態的圖。 FIG. 21 is a diagram showing a state where the center position of the suction head 141 is detected by the top vision 155.

鍵合拾取器140沿Y軸方向移動，以使吸頭141位於上視視覺155的上部。並且，上視視覺155藉由對吸頭141進行成像來檢測吸頭141的中心位置，並檢測各吸頭141的吸附孔174a的位置。 The bonding picker 140 is moved in the Y-axis direction so that the suction head 141 is positioned on the upper part of the upper vision 155. In addition, the upward vision 155 detects the center position of the suction head 141 by imaging the suction head 141, and detects the position of the suction hole 174 a of each suction head 141.

第22圖是表示上視視覺155檢測形成在片狀塊162上的基準孔164的狀態的圖。 22 is a diagram showing a state in which the top vision 155 detects the reference hole 164 formed in the sheet-like block 162.

晶片搬運器160沿Y軸方向移動，以使片狀塊162位於上視視覺155的上部。此時，可預先儲存晶片搬運器160沿Y軸方向移動的距離。 The wafer carrier 160 is moved in the Y-axis direction so that the sheet-like block 162 is positioned on the upper part of the top view 155. At this time, the distance that the wafer carrier 160 moves in the Y-axis direction may be stored in advance.

並且，上視視覺155可藉由對形成在片狀塊162下部的基準孔進行成像，來獲取吸頭141中心位置和基準孔164中心位置之間的偏移距離D1。此時，形成在晶片搬運器160上的基準孔164的中心位置和打孔裝置170的中心位置之間的距離D2為設定值，是預先存儲的值。 In addition, the upward vision 155 can obtain the offset distance D1 between the center position of the suction head 141 and the center position of the reference hole 164 by imaging a reference hole formed in the lower portion of the sheet-like block 162. At this time, the distance D2 between the center position of the reference hole 164 formed on the wafer carrier 160 and the center position of the punching device 170 is a set value and is a value stored in advance.

即，上視視覺155檢測基準孔164的中心位置，從而可獲得打孔裝置170的位置資訊。 That is, the top vision 155 detects the center position of the reference hole 164, so that the position information of the punching device 170 can be obtained.

並且，藉由上述資訊，可知吸頭141的中心位置與打孔裝置170的中心位置之間的距離。即，吸頭141的中心位置與打孔裝置170的中心位置之間的距離為：在基準孔164的中心位置與打孔裝置170的中心位置之間的距離D2上，反應此前獲取的吸頭141的中心位置與基準孔164中心位置間的偏移距離D1的距離。 In addition, from the above information, the distance between the center position of the suction head 141 and the center position of the punching device 170 can be known. That is, the distance between the center position of the suction head 141 and the center position of the punching device 170 is: The distance D2 between the center position of the reference hole 164 and the center position of the punching device 170 reflects the tip obtained previously. The distance of the offset distance D1 between the center position of 141 and the center position of the reference hole 164.

因此，將片狀塊162向Y軸方向移動相當於反應至此間距反應偏移距離D1並求得的距離，即吸頭141的中心位置與打孔裝置170的中心位置之間的距離，以便使吸頭141的中心位置與打孔裝置170的中心位置一致。 Therefore, moving the sheet-shaped block 162 in the Y-axis direction is equivalent to the distance obtained by reacting to this distance and offsetting the distance D1, that is, the distance between the center position of the tip 141 and the center position of the punching device 170, so that The center position of the suction head 141 coincides with the center position of the punching device 170.

藉由上述校正過程，將吸頭141的銷容納孔172a和打孔裝置170的打孔銷171的位置設置一致，從而能夠對齊將吸頭141和打孔裝置170的位置。 Through the above-mentioned correction process, the positions of the pin receiving holes 172 a of the suction head 141 and the punching pins 171 of the punching device 170 are set to be the same, so that the positions of the suction head 141 and the punching device 170 can be aligned.

第24圖是表示上視視覺155檢查單元拾取器130吸附的半導體晶片P的狀態的圖，第25圖是表示半導體晶片P的焊錫球面上附著有異物D和發生裂紋C的狀態的圖。 FIG. 24 is a diagram showing a state in which the semiconductor wafer P sucked by the unit pickup 130 is inspected by the top-view 155 inspection, and FIG. 25 is a diagram showing a state in which foreign matter D is attached to the solder ball surface of the semiconductor wafer P and a crack C is generated.

After the top vision 155 inspects the solder sphere (or bump surface) of the semiconductor wafer P, the semiconductor wafer P is placed on the chip block 162 of the wafer carrier 160.

此時，若上視視覺155預先檢查焊錫球面，篩選出不良半導體晶片P，則判斷為不良的半導體晶片不會進入鍵合過程，而進行廢棄 處理。即，可利用上視視覺155預先檢查半導體晶片上的異物，由此防止不良半導體晶片鍵合於基板上。 At this time, if the upward vision 155 inspects the solder spheres in advance and screens out the defective semiconductor wafer P, the semiconductor wafer judged to be defective will not enter the bonding process and will be discarded. deal with. That is, foreign matter on the semiconductor wafer can be inspected in advance using the top-view vision 155, thereby preventing defective semiconductor wafers from being bonded to the substrate.

參照第25圖，上視視覺155可檢查半導體晶片P的焊錫球面存在裂紋C或黏附異物D的狀態。 Referring to FIG. 25, the top vision 155 can check the state where the solder spherical surface of the semiconductor wafer P has a crack C or a foreign matter D adhered thereto.
