Description

半導體晶片洗淨方法及半導體晶片洗淨裝置Semiconductor wafer cleaning method and semiconductor wafer cleaning device

本揭示是有關於一種進行半導體晶片的洗淨的半導體晶片洗淨方法及半導體晶片洗淨裝置。The present disclosure relates to a semiconductor wafer cleaning method and a semiconductor wafer cleaning device for cleaning semiconductor wafers.

半導體晶片是將8吋或12吋大小的晶圓切斷成規定的大小而製造。於切斷時,為了不使所切斷的半導體晶片分散,於背面貼附切割薄膜,自表面側利用切割鋸或雷射光線等來將晶圓切斷。此時,貼附於背面的切割薄膜被稍微切入,但處於不被切斷而保持各半導體晶片的狀態。然後,經切斷的各半導體晶片被逐個自切割薄膜拾取並被輸送至倒裝晶片接合等下一工序。Semiconductor wafers are manufactured by cutting 8-inch or 12-inch wafers into predetermined sizes. During cutting, in order not to disperse the cut semiconductor wafer, a dicing film is attached to the back surface, and the wafer is cut from the surface side with a dicing saw or a laser beam. At this time, the dicing film attached to the back surface is slightly cut in, but it is in a state where each semiconductor wafer is held without being cut. Then, the cut semiconductor wafers are picked up one by one from the dicing film and transported to the next process such as flip chip bonding.

於切割時,半導體晶圓的切削屑或切割薄膜的切削屑等異物附著於半導體晶片的表面上,因此於切割時或者切割後對半導體晶片的表面或者經切斷的晶圓的表面進行洗淨。半導體晶片的洗淨例如如日本專利特開2003-257912號公報所記載般,有時使用將洗淨流體吹附至半導體晶片的方法。During dicing, foreign matter such as chips from the semiconductor wafer or chips from the dicing film adheres to the surface of the semiconductor wafer. Therefore, the surface of the semiconductor wafer or the surface of the cut wafer is cleaned during or after dicing. . For cleaning of semiconductor wafers, as described in, for example, Japanese Patent Application Laid-Open No. 2003-257912, a method of blowing a cleaning fluid to the semiconductor wafer may be used.

另外,於進行對晶圓的表面進行鏡面研磨的精加工之後,進行用於對晶圓的表面進行清潔化的洗淨。例如,於日本專利第4675448號公報中提出了使用鹼系洗淨液或酸系洗淨液或者臭氧水來進行洗淨。In addition, after performing the finish machining of mirror-polishing the surface of the wafer, washing for cleaning the surface of the wafer is performed. For example, in Japanese Patent No. 4675448, it is proposed to use an alkali-based cleaning solution, an acid-based cleaning solution, or ozone water for cleaning.

近年來,多使用將其他半導體晶片直接接合於半導體晶片上的直接接合。於進行直接接合的情況下,即使於表面上附著有幾微米~亞微米大小的微細的異物,亦存在接合品質下降的情況。In recent years, direct bonding in which other semiconductor wafers are directly bonded to semiconductor wafers has been frequently used. In the case of direct bonding, even if fine foreign matter of a few micrometers to sub-micrometer size adheres to the surface, the bonding quality may be degraded.

另一方面,於專利文獻1、專利文獻2所記載的現有技術的洗淨方法中,能夠以幾十微米左右的大小進行異物的去除,但難以進行如於直接接合中成為問題般的幾微米~亞微米的微細的異物的去除。On the other hand, in the prior art cleaning methods described in Patent Document 1 and Patent Document 2, foreign matter can be removed with a size of about several tens of microns, but it is difficult to perform a few microns as a problem in direct bonding. ~ Removal of sub-micron fine foreign matter.

接著,參照圖3~圖7,使用以如上方式構成的半導體晶片洗淨裝置100來對半導體晶片11的表面的洗淨工序及半導體晶片洗淨方法進行說明。Next, referring to FIGS. 3 to 7, the cleaning process of the surface of the semiconductor wafer 11 and the semiconductor wafer cleaning method will be described using the semiconductor wafer cleaning apparatus 100 configured as described above.

如圖3的步驟S101所示,於晶圓製造工序中所製造的晶圓10如圖4所示般貼附於切割薄膜30的上表面上。切割薄膜30包括基材31及覆蓋基材31的上表面的黏著層32,於黏著層32的上表面上貼附有晶圓10。As shown in step S101 of FIG. 3, the wafer 10 manufactured in the wafer manufacturing process is attached to the upper surface of the dicing film 30 as shown in FIG. 4. The dicing film 30 includes a substrate 31 and an adhesive layer 32 covering the upper surface of the substrate 31, and a wafer 10 is attached to the upper surface of the adhesive layer 32.

圖3的步驟S102所示的切割工序是由切割裝置執行。所謂切割裝置,是將貼附於切割薄膜30的半導體的晶圓10切斷而製成半導體晶片11的裝置。切割裝置如圖5所示般於晶圓10上刻畫切口14而將晶圓10切斷成多個半導體晶片11。此時,切割薄膜30的黏著層32亦與晶圓10一起被切斷。於切割工序中,當於晶圓10上刻畫切口14時,產生如矽的切屑等無機系的異物15及黏著層32的切屑般的有機系的異物16。該些異物15、16中的較大者是於圖3的步驟S103所示的切割後洗淨工序中被去除。但是,幾微米~亞微米級的微細的異物15、異物16未被去除,如圖5所示,無機系的微細的異物15處於附著於半導體晶片11的表面上或與切口14面對面的半導體晶片11的側面上的狀態。另外,有機系的微細的異物16處於附著於半導體晶片11的上表面上的狀態。The cutting process shown in step S102 of FIG. 3 is executed by the cutting device. The dicing device is a device that cuts the semiconductor wafer 10 attached to the dicing film 30 to form a semiconductor wafer 11. As shown in FIG. 5, the dicing device scribes a notch 14 on the wafer 10 to cut the wafer 10 into a plurality of semiconductor wafers 11. At this time, the adhesive layer 32 of the dicing film 30 is also cut together with the wafer 10. In the dicing process, when the notch 14 is carved on the wafer 10, inorganic foreign materials 15 such as silicon chips and organic foreign materials 16 such as chips of the adhesive layer 32 are generated. The larger of these foreign substances 15 and 16 is removed in the post-cutting cleaning process shown in step S103 of FIG. 3. However, the fine foreign matter 15 and foreign matter 16 of a few micrometers to submicron order are not removed. As shown in FIG. 5, the inorganic fine foreign matter 15 is attached to the surface of the semiconductor wafer 11 or facing the cutout 14 State on the side of 11. In addition, the organic fine foreign matter 16 is in a state of being attached to the upper surface of the semiconductor wafer 11.

接著,如圖3的步驟S201所示,執行氣體溶解水洗淨工序。氣體溶解水洗淨工序是自氣體溶解水噴嘴61將氣體溶解水噴射至半導體晶片11的表面來對半導體晶片11的表面進行洗淨的工序。氣體溶解水於通過氣體溶解水噴嘴61時被超音波振盪器62超音波振動,而成為包含微細的泡者。該微細的泡於半導體晶片11的表面或切口14中發泡,利用其衝擊來去除半導體晶片11的表面的微細的無機系的異物15。於使用氫水作為氣體溶解水的情況下,氫水不會腐蝕有機物,因此可於不損傷作為有機物的切割薄膜30的基材31的情況下去除無機系的異物15。另外,由於藉由氫水而表面的氧化得到抑制,因此可將半導體晶片11的表面精加工成未氧化的表面。進而,當使用添加鹼的氫水時,可抑制經去除的異物15再次附著於半導體晶片11的表面上,因此可進一步提高洗淨後的半導體晶片11的表面的清潔度。Next, as shown in step S201 of FIG. 3, a gas-dissolved water washing process is performed. The gas-dissolved water cleaning step is a step in which gas-dissolved water is sprayed onto the surface of the semiconductor wafer 11 from the gas-dissolved water nozzle 61 to clean the surface of the semiconductor wafer 11. When the gas-dissolved water passes through the gas-dissolved water nozzle 61, it is ultrasonically vibrated by the ultrasonic oscillator 62, and becomes one containing fine bubbles. This fine bubble foams in the surface of the semiconductor wafer 11 or the cutout 14, and the impact removes the fine inorganic foreign matter 15 on the surface of the semiconductor wafer 11. In the case of using hydrogen water as the gas-dissolved water, the hydrogen water does not corrode organic matter, and therefore, the inorganic foreign matter 15 can be removed without damaging the substrate 31 of the dicing film 30 which is the organic matter. In addition, since oxidation of the surface is suppressed by the hydrogen water, the surface of the semiconductor wafer 11 can be finished to an unoxidized surface. Furthermore, when alkali-added hydrogen water is used, the removed foreign matter 15 can be prevented from adhering to the surface of the semiconductor wafer 11 again, so the cleanliness of the surface of the semiconductor wafer 11 after washing can be further improved.

另一方面,由於氫水不腐蝕有機物,因此無法去除如附著於半導體晶片11的上表面上的黏著層32的切屑般的有機系的微細的異物16,即使氣體溶解水洗淨工序結束,如圖6所示,於半導體晶片11的上表面上,亦附著有機系的微細的異物。因此,進入圖3的步驟S202,執行擦拭洗淨工序。On the other hand, because hydrogen water does not corrode organic matter, it is impossible to remove organic fine foreign matter 16 such as chips attached to the adhesive layer 32 on the upper surface of the semiconductor wafer 11. Even if the gas-dissolved water cleaning process is completed, such as As shown in FIG. 6, on the upper surface of the semiconductor wafer 11, organic fine foreign matter is also attached. Therefore, it progresses to step S202 of FIG. 3, and a wiping cleaning process is performed.

擦拭洗淨工序是以下工序:一面自洗淨液噴嘴72使洗淨液於半導體晶片11的表面連續地流動,一面藉由旋轉驅動部75使安裝於擦拭臂70的前端的擦拭構件保持部73旋轉,藉由推壓機構76將安裝於擦拭構件保持部73的擦拭構件74推壓至半導體晶片11的表面上,而對附著於半導體晶片11的表面上的有機系的異物16進行擦拭。The wiping cleaning process is a process in which the cleaning liquid is continuously flowed from the cleaning liquid nozzle 72 on the surface of the semiconductor wafer 11, and the wiping member holding portion 73 attached to the tip of the wiping arm 70 is driven by the rotation drive unit 75 By rotating, the wiping member 74 mounted on the wiping member holding portion 73 is pressed against the surface of the semiconductor wafer 11 by the pressing mechanism 76 to wipe the organic foreign matter 16 adhering to the surface of the semiconductor wafer 11.

於擦拭洗淨工序中,亦可使擦拭構件保持部73自轉。再者,藉由旋轉台50的旋轉,擦拭構件保持部73繞旋轉軸52公轉。另外,亦可藉由XY驅動部77使臂本體71於XY方向上移動。另外,亦可藉由旋轉驅動部75使擦拭構件保持部73繞旋轉軸52公轉。另外,於擦拭洗淨工序時,可藉由推壓機構76中的按壓力調整機構來進行將擦拭構件74向半導體晶片11的表面的推壓壓力的調整,亦可藉由推壓機構76中的按壓量調整機構來調整擦拭構件74向半導體晶片11的推壓量。In the wiping and washing process, the wiping member holding portion 73 may be rotated. Furthermore, by the rotation of the rotating table 50, the wiping member holding portion 73 revolves around the rotating shaft 52. In addition, the arm main body 71 may be moved in the XY direction by the XY drive unit 77. In addition, the wiping member holding portion 73 may revolve around the rotation shaft 52 by the rotation driving portion 75. In addition, in the wiping and cleaning process, the pressing force adjustment mechanism of the pressing mechanism 76 can be used to adjust the pressing pressure of the wiping member 74 to the surface of the semiconductor wafer 11, or the pressing mechanism 76 The pressing amount adjustment mechanism adjusts the pressing amount of the wiping member 74 to the semiconductor wafer 11.

藉由擦拭洗淨工序可有效地自半導體晶片11的表面去除有機系的異物16。此處,作為洗淨液,可使用純水、氫水、添加鹼的氫水、碳酸水等。於使用氫水、添加鹼的氫水、碳酸水的情況下,可抑制靜電的產生。The wiping cleaning process can effectively remove organic foreign matter 16 from the surface of the semiconductor wafer 11. Here, as the cleaning liquid, pure water, hydrogen water, alkali-added hydrogen water, carbonated water, or the like can be used. In the case of using hydrogen water, alkali-added hydrogen water, or carbonated water, the generation of static electricity can be suppressed.

然後,當擦拭洗淨工序結束後,有機系的微細的異物16被自半導體晶片11的表面去除,半導體晶片11的表面成為如圖8所示般的清潔的表面。然後,如圖3的步驟S301所示,具有清潔的表面的半導體晶片11於接合裝置中接合於另一半導體晶片11或者基板上。再者,亦可設為於圖3的步驟S202所示的擦拭洗淨工序之後執行乾燥工序,並使半導體晶片11乾燥後進行接合。再者,接合裝置例如是倒裝晶片接合裝置,但只要是晶粒接合裝置等將半導體晶片11接合於被接合物的裝置,則可使用。Then, after the wiping cleaning step is completed, the organic fine foreign matter 16 is removed from the surface of the semiconductor wafer 11, and the surface of the semiconductor wafer 11 becomes a clean surface as shown in FIG. 8. Then, as shown in step S301 of FIG. 3, the semiconductor wafer 11 with a clean surface is bonded to another semiconductor wafer 11 or a substrate in a bonding device. Furthermore, the drying process may be performed after the wiping cleaning process shown in step S202 of FIG. 3, and the semiconductor wafer 11 may be dried and then bonded. In addition, the bonding apparatus is, for example, a flip-chip bonding apparatus, but it can be used as long as it is a device for bonding the semiconductor wafer 11 to an object to be bonded, such as a die bonding apparatus.

如以上所說明般,實施方式的半導體晶片洗淨裝置100可進行附著於半導體晶片11的表面上的微細的異物15、異物16的去除。As described above, the semiconductor wafer cleaning apparatus 100 of the embodiment can remove the fine foreign matter 15 and the foreign matter 16 adhering to the surface of the semiconductor wafer 11.

另一方面,如圖8所示,於現有技術的洗淨方法中,即使於洗淨後,於半導體晶片11的表面上亦殘留有幾微米~亞微米級的無機系的異物15或有機系的異物16。因此,於自切割薄膜30剝離半導體晶片11時,附著於半導體晶片11的表面上的異物15如箭頭91所示,落下至鄰接的半導體晶片11的表面上。當將半導體晶片11直接接合於落下至半導體晶片11的表面上的異物15上時,有時由於異物15而無法進行良好的接合。On the other hand, as shown in FIG. 8, in the conventional cleaning method, even after cleaning, there are still a few micrometers to submicron level inorganic or organic foreign matter 15 on the surface of the semiconductor wafer 11.的外物16。 The foreign body 16. Therefore, when the semiconductor wafer 11 is peeled from the dicing film 30, the foreign matter 15 attached to the surface of the semiconductor wafer 11 falls onto the surface of the adjacent semiconductor wafer 11 as indicated by the arrow 91. When the semiconductor wafer 11 is directly bonded to the foreign material 15 dropped on the surface of the semiconductor wafer 11, the foreign material 15 may not be able to perform good bonding.

但是,根據實施方式的半導體晶片洗淨裝置100,由於可去除附著於半導體晶片11的表面上的微細的異物15、異物16,因此可提高直接接合時的接合品質。However, according to the semiconductor wafer cleaning apparatus 100 of the embodiment, since the fine foreign matter 15 and the foreign matter 16 adhering to the surface of the semiconductor wafer 11 can be removed, the bonding quality at the time of direct bonding can be improved.

於以上說明的實施方式的半導體晶片洗淨裝置100中,對進行貼附於切割薄膜30上的半導體晶片11的表面的洗淨進行了說明,但不限於此,例如,亦可應用於以下情況:於切割洗淨工序之後,自經切割的多個半導體晶片11中僅拾取良品的半導體晶片11並經由黏著劑貼附於玻璃板上,貼附有多個半導體晶片11並將玻璃板載置於旋轉台50上來進行半導體晶片11的表面的洗淨。於此情況下,玻璃板構成支持材。另外,亦可設為並非玻璃板,而是於矽晶圓或者基板上貼附半導體晶片11,將矽晶圓或者基板載置於旋轉台50來進行半導體晶片11的洗淨。於此情況下,矽晶圓、基板構成支持材。In the semiconductor wafer cleaning apparatus 100 of the above-described embodiment, the cleaning of the surface of the semiconductor wafer 11 attached to the dicing film 30 has been described, but it is not limited to this, for example, it can also be applied to the following cases : After the dicing and cleaning process, only the good semiconductor wafers 11 are picked up from the diced semiconductor wafers 11 and attached to the glass plate via an adhesive, the multiple semiconductor wafers 11 are attached and the glass plate is placed The surface of the semiconductor wafer 11 is cleaned on the rotating table 50. In this case, the glass plate constitutes the support material. In addition, instead of a glass plate, the semiconductor wafer 11 may be attached to a silicon wafer or substrate, and the silicon wafer or substrate may be placed on the turntable 50 to clean the semiconductor wafer 11. In this case, the silicon wafer and the substrate constitute the support material.

接著,參照圖9至圖11對實施方式的半導體晶片洗淨裝置100的另一洗淨工序進行說明。對於與之前參照圖3所說明的洗淨工序相同的工序,標註相同的符號並省略說明。Next, another cleaning process of the semiconductor wafer cleaning apparatus 100 of the embodiment will be described with reference to FIGS. 9 to 11. The steps that are the same as the cleaning steps described above with reference to FIG. 3 are denoted by the same reference numerals, and descriptions thereof will be omitted.

圖9所示的洗淨工序如圖9的步驟S201所示於切割工序之後實施氣體溶解水洗淨工序,然後,於步驟S202中執行擦拭洗淨工序,然後,於圖9的步驟S203中再次執行氣體溶解水洗淨工序。藉此,可更有效地去除無機系的微細的異物15。The cleaning process shown in FIG. 9 is shown in step S201 of FIG. 9. After the cutting process, a gas-dissolved water cleaning process is performed. Then, the wiping cleaning process is performed in step S202, and then again in step S203 of FIG. Perform gas-dissolved water cleaning process. Thereby, the inorganic fine foreign matter 15 can be removed more effectively.

圖10所示的洗淨工序如圖9的洗淨工序般,於步驟S202中執行擦拭洗淨工序之後,於S203中再次執行氣體溶解水洗淨工序,然後,進而於步驟S204中執行臭氧水洗淨工序。The cleaning process shown in FIG. 10 is similar to the cleaning process of FIG. 9. After the wiping cleaning process is performed in step S202, the gas-dissolved water cleaning process is performed again in S203, and then ozone water is performed in step S204. Washing process.

臭氧水洗淨工序自氣體溶解水噴嘴61噴出將臭氧溶解於水中而成的臭氧水來對半導體晶片11的表面進行洗淨。藉由追加臭氧水洗淨工序,可更有效地去除有機系的微細的異物16。In the ozone water cleaning step, ozone water obtained by dissolving ozone in water is sprayed from the gas-dissolved water nozzle 61 to clean the surface of the semiconductor wafer 11. By adding the ozone water washing process, organic fine foreign matter 16 can be removed more effectively.

圖11所示的洗淨工序不進行圖3的步驟S103所示的切割後洗淨工序,僅進行氣體溶解水洗淨工序及擦拭洗淨工序。藉此,可縮短洗淨工序。The cleaning process shown in FIG. 11 does not perform the post-cut cleaning process shown in step S103 of FIG. 3, and only performs the gas-dissolved water cleaning process and the wiping cleaning process. Thereby, the washing process can be shortened.

再者,於參照圖9至圖11所說明的洗淨工序中,亦可分別於作為最後的洗淨工序的氣體溶解水洗淨工序、臭氧水洗淨工序、擦拭洗淨工序之後實施乾燥工序,使半導體晶片11的表面乾燥。Furthermore, in the cleaning process described with reference to FIGS. 9 to 11, the drying process may be performed after the gas-dissolved water cleaning process, the ozone water cleaning process, and the wiping cleaning process as the final cleaning process. , The surface of the semiconductor wafer 11 is dried.

亦可構成為:將實施方式的半導體晶片洗淨裝置100與接合裝置一體地配置,並將洗淨後的清潔的半導體晶片11供給至接合裝置。藉此,可將清潔度更高的半導體晶片11供給至接合裝置。It may be configured such that the semiconductor wafer cleaning device 100 of the embodiment is integrated with the bonding device, and the cleaned semiconductor wafer 11 is supplied to the bonding device. Thereby, the semiconductor wafer 11 with higher cleanliness can be supplied to the bonding device.

另外,亦可將實施方式的半導體晶片洗淨裝置100與切割裝置一體地配置。例如,代替切割裝置的切割洗淨裝置,而將半導體晶片洗淨裝置100一體地組裝於切割裝置中,可自半導體晶片11的表面去除於切斷晶圓10時附著於半導體晶片11的表面上的無機系及有機系的微細的異物15、異物16。In addition, the semiconductor wafer cleaning device 100 of the embodiment and the dicing device may be integrally arranged. For example, instead of the dicing and cleaning device of the dicing device, the semiconductor wafer cleaning device 100 is integrated into the dicing device, which can be removed from the surface of the semiconductor wafer 11 and attached to the surface of the semiconductor wafer 11 when the wafer 10 is cut. Inorganic and organic fine foreign matter 15, foreign matter 16.
