Description of the Invention: [Technical Field of the Invention] The present invention relates to a structure of a bonding apparatus and a method of correcting a bonding position when the bonding apparatus is joined. [Prior technology] In recent years, in order to meet the demand for miniaturization of electronic equipment, the fine pitch of semiconductor elements has been made. When such a fine pitch semiconductor element is fabricated to fabricate a sheep conductor package, a flip-chip for bonding a semiconductor wafer of an upper and lower inversion to a surface of a substrate on which a pin is formed to bond an electrode of the semiconductor wafer to a lead is used. the way. When the semiconductor wafer is bonded to the substrate by such a flip chip method, the position of the electrode of the semiconductor wafer and the substrate pin position % are aligned at the ordering position, and the semiconductor wafer and the substrate are reversed. The upper and lower two-view cameras are inserted, and the electrode faces of the semiconductor wafer and the lead faces of the substrate are simultaneously taken, and the position of the semiconductor wafer and the position of the substrate are detected from the image for positioning (see, for example, Patent Document). Moreover, since the junction between the electrode and the pin is from an externally invisible position, when the electrode of the semiconductor wafer is inspected for bonding to a predetermined position of the lead, the semiconductor wafer is temporarily peeled off and combined by microscopic observation. In the state of the surface, there is a problem that the inspection takes time and steps (see, for example, Patent Document 2). Therefore, a light-transmitting belt carrier that bonds a semiconductor wafer has been proposed (see, for example, Patent Wire 3). Moreover, in the method proposed in Patent Document 3, 201103095 is to monitor the semiconductor wafer by transmitting the light from the camera pole and the pin nose electrode and the offset side to the surface of the semiconductor chip and the pin carrier. The electric signal is offset by the image recognition device to transport the wafer or the substrate to the position of the positionless pin. The contact is formed by aligning the pins formed in parallel with the inversion plate to perform the electrical conductor wafer bonding to the light transmissive property of the light transmissive tape carrier, according to the image pin The positional shift is such that the semiconductor is moved to automatically correct the electrode and the method proposed in Patent Document 1 is to obtain the electrode image of the image of the pin of the flexible flexible substrate, and then align the positions of the flexible base. Further, in Patent Document 2, it is proposed to correct the positional displacement of the electrode and the lead of the semiconductor which is caused by the temperature increase of the connection by the operation of the bonding apparatus. The method is disposed on the back side of the light-transmitting film. The camera at the position of the semi-conductor: photographs the image of the electrode of the wafer and the pin of the film bonded to the light-transmitting film, and manually corrects the offset amount of the transfer arm based on the image. [Patent Document 1] JP-A-2004-214705 [Patent Document 2] Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. When the semiconductor wafer is bonded to the substrate, the following substrate is used, and the substrate is adsorbed and fixed to the heater of the bonded carrier by the offset without being offset, so that the reversed semiconductor aw is attached. The wafer is heated by a built-in heater to heat the semiconductor wafer. The 201103095 tool is lowered to the bonding position, and the electrode of the heated semiconductor wafer is pressed tightly to the pin of the heated substrate. Since the bonding stage is disposed on the surface side opposite to the surface on which the lead of the substrate is formed, even if the substrate is light-transmitting, when the substrate is adsorbed and fixed to the bonding stage, the pin cannot be seen from the bonding stage side. s position. Therefore, it is difficult to monitor the contact state between the electrode and the lead of the semiconductor wafer from the back surface of the light-transmitting tape body by the camera, as in the conventional technique described in Patent Document 3, after the substrate is adsorbed on the bonding stage. Automatically corrects the positional offset between the electrode and the pin. Further, according to the conventional technique described in Patent Document 3, the position of the electrode of the semiconductor wafer and the position of the lead are aligned in a state where the substrate is separated from the bonding stage, and then the substrate is adsorbed and fixed to the substrate after the bonding stage. The position is offset and cannot be joined to the correct position, which sometimes causes the joint quality to deteriorate. Similarly, even if the conventional substrate described in Patent Document 1 is used, it is fixed to the bonding stage '0 after the movable substrate is moved, and this may be prevented from being bonded to the correct position due to the shift at the time of fixing. Sometimes the problem of poor joint quality is caused. On the other hand, in the conventional technique described in Patent Document 2, since the camera is disposed at a position separated from the bonding stage, there is no problem that the bonding stage cannot see the electrode and the lead from the back side of the light transmitting substrate. . However, as in the conventional technique described in Patent Document 2, when the position of the electrode and the lead of the semiconductor wafer is to be detected by the image, it is difficult to mechanically process it in a short time due to the acquired image. If the operation of the y-joining is stopped, the amount of the transfer arm must be adjusted by the person watching the monitoring screen. The position of the electrode and the pin are offset. Since the temperature of the joint device varies with time, it is necessary to stop and adjust the number of two in the joint device A K. This has the problem of causing the joint device to reduce the rate of transfer. This problem, when the system makes most of the joints ' < 锝 τ τ, the title strives to be serious. Further, it is only necessary to reduce the frequency of adjustment of the offset amount of the transfer arm, that is, to increase the operating rate of the bonding device, but there is also a problem that the offset between the electrode and the lead is increased, which deteriorates the bonding quality. From "卞牛, low and improved bonding quality.

The material conductor wafer 4 has extended holes IS, μ... 41 and a true heater attached to the adsorption surface 10: internal mounting Used to heat the adsorbed semiconductor crystal... Directional drive: 2::: 'Equipped with the end of the bonding tool 12 toward the end of the tool 12 Μ π & 鞑, by the drive Ζ direction motor to make the joint 8 1 ζ刖The crucible is driven at 7°° so that the semiconductor wafer 41 adsorbed to the front end 201103095 of the bonding tool 12 can be straightened to the surface 45a of the strip 45. Further, by moving the bonding head 1 1 in the Χγ direction The bonding tool 12 and the semiconductor day piece 41 adsorbed to the tip end of the bonding tool 12 can be moved in the x direction. As shown in Fig. 1, the joint w 〇 24' is attached to the base 23 of the support base 21 through the heat intercepting material 22, and the vacuum is attached to the suction surface 27 of the 体 ^ ^ * and the attachment body 45. The vacuum of the body 45 is $w^^4, ^^, and a heater 25 for heating the adsorbed strip 45 is installed inside. The _ _ ^ and the bottom 23 are internally assembled with a moving mechanism for moving the joining stage 24 up and down in the Z direction, and are raised to adhere to the back surface 45b of the belt body 45 at the time of joining. The belt 45 can be vacuum-adsorbed in a private position and in a position, and when the belt 45 is fed in the direction of the arrow in the figure after the joining, the suction surface 27 is lowered so as not to hinder the movement of the belt 45. As shown in Fig. 1, the machine mounting arm portion 33 is fixed to the base plate n to which the mating stage is attached. The arm portion 33 has a camera 31 attached to the front end of the belt body 45 from the base plate to the end portion. Camera ^Configuration: The position of the 囟5b is mounted so as to face the belt body 45, and the illumination LED 32 is attached around the camera 31. This coffee 2 can also be formed in a ring shape at the peripheral portion of the camera 31. As shown in Fig. i, the bonding apparatus 100 is provided with two/60 of the overall control engagement operation. The control unit 6 is configured to execute the control program 68, the edge detection program 66, and the correction program 67 2 by referring to the control data 69 stored in the memory 65 by the CPU 61 - while the CPU 6 is included in the internal memory. Control of the engagement device 100. As shown in FIG. 1, the bonding head U and the salvage carrier 24 are respectively connected to the bonding head interface 62 and the bonding stage interface, and are operated by the command of the control unit 60. The camera 31 is connected to the control unit 12 201103095 60. The camera interface 64' can send the image obtained by controlling the captured scene to the picture shown in Figure 2. On the surface of the strip 45, the back Ma is formed with a complex array of ribbon pins, and the set of pins and semiconductor wafers. The electrode of 41 is formed by a corresponding number 'pin 46' to the semiconductor wafer. The side extension 46 can also be formed, for example, by plating or the like. Further, a hole 48 is formed on both sides of the belt body μ, and the hole 48 is engaged with a feeding mechanism for extending the belt body 45 in the direction of the arrow a in the figure. Further, the belt body 45 can be transported by a feeding mechanism that is conveyed while being held by a clip (not shown). As shown in Fig. 3, since the strip 45 is permeable to the rust, the semiconductor wafer 41 is joined when viewed from the lunar surface 45b of the strip 45. μ is any 0 on the surface 45a of the tribute 45 and the electrode 42 of the semiconductor wafer 41 is bonded to the slanting foot 4 ^ ^ ^, that is, the light transmissive strip 45 is seen through the lead 46, the electrode 42, the main track μ The potential 42 and the surface of the + conductor wafer 41 on the electrode 42 side. As shown in Fig. 3, the lead 46 in the vicinity of the land portion 42 is linearly extended in a strip shape having a width Wi. Further, the electrode a has a width w2 which is wider than the width Wi of the pin and whose length 短 is shorter than the length of the pin 。. Further, after the electrode 42 is bonded to the lead 46, the pin 延伸 extends from the electrode 42 to the long side of the lead 46, and the electrode 42 extends beyond the width of the lead. Since the lead 46 does not transmit light, the electrode 42' of the portion where the pole 42 is overlapped is not visible from the back of the strip 45, and only the electrode 42 shown by the diagonal line in the figure is beyond the lead 46. Partially visible through the body 45. The operation of the joining device 1A configured as described above will be described. After the bonding apparatus 100 starts to operate, the optically transmissive strip 45 is sent to the predetermined position by the predetermined position body 45 sent to the bonding stage 24 by the feeding mechanism 13 201103095 feeding mechanism. The adsorption surface η of the 'joining stage' is raised to a position close to the back surface of the belt body 45, and the vacuum hole 26 is vacuumed to adsorb the belt body 45 to the joining stage 24, and the belt body 4 is heated. The bonding head U is moved in the χγ direction, and the position of the electrode 42 of the semiconductor wafer 吸附 adsorbed by the front end of the bonding tool 12 is detected by the unillustrated camera and the position of the pin 46 is aligned, and the semiconductor wafer 41 is placed. The position is positioned as the joint position. After the alignment of the position is completed, the motor mounted on the joint head u is driven to be connected. The tool 12 is lowered toward the surface 45& of the belt body 45, and is attracted to the suction surface 16 of the front end of the bonding tool 12, The electrode 42 of the heated semiconductor wafer 41 is pressed against the pin 46' of the strip 45 by heat and pressure 42 and the lead 46. a after the end of the bonding operation 'rises the bonding tool 12 and causes the bonding carrier 24 Down. Then, The belt body 45, which is not shown, feeds the belt 45 to the next stage 46 in the direction of the arrow & Fig. 1 to the joining stage 24, and performs the second 'joining. Then, the joining is completed. The portion 1 of the lead 46 is sequentially sent to the direction of the arrow a. Then, 'when the portion of the strip 45 to which the semiconductor wafer 41 is bonded is sent to the camera 31, the control unit 60 is mounted on the camera 3mED32. The back surface 45b of the illumination strip 45 obtains a fir image as shown in Fig. 3 in its field of view. Then, the lead edges 46a, 46b of the lead 46 and the electrode edge 42a of the electrode 42 are obtained as follows. 42b. The control unit 60, as shown in step S1〇1 of FIG. 4 and FIG. 3, selects the first range 51 including the image of the pin 46 and does not include the image of the electrode η from the image 14 201103095. The position of the self-contained body 45 and the configuration of the pin 46: the position of the page 夂. Further, since the lead 46 and the electrode 42 and the semiconductor wafer 4 are taken by illumination from the light-transmissive tape body ! : an image of the surface on the electrode side, so the area without the semiconductor wafer 41 does not reflect the pin 46 King black background. Therefore, it is also possible to search for the darker portion of the pin a as the first region. After the control unit 60 selects the first range 51, the video data of the range is stored in the memory 65 by, for example, binarization processing as shown in step S1 of Fig. 4 . Further, the control unit 6 is set as the second range 52 in a range including the pair of lead edges 46a and 46b and narrower in the Y direction than the first range 5 1 as shown in Fig. 4 . Further, as shown in FIG. 4 and FIG. 3, the second range _ is made by, for example, binarization processing, and as shown in step 4 of FIG. 4, the gate is opposite to the lead 46. The lead edges 46a, 46b extend from the first side 'edge 42c of the electrode 42 in the vertical direction. Since the width % of the electrode 42 is larger than the width of the leg 46 and the electrode exceeds the width direction of the image of the pin μ by the image, and the i-th edge 42c must appear on the foot 4 w :: the second edge, thus at the first edge TM, Control unit I. : Perform the data processing of the range in which the i-th: the pin 46 of the circle 52 overlaps, and the search of the edge 42c. This allows for a quicker check. After the i-th edge 42e is detected, the control unit stores the 4th position in the memory 65. Edge 42〇 control. P60, as shown in Fig. 4, step S1〇6w} 15 201103095 - Step 2 moves the second fan 52, and the same method is detected similarly to the detection of the electrode 4 edge 42c. Next, the second edge 42d rear body 65 is hatched on the second edge of the second edge of the second 'Xi' edge. Then, as shown in step _7 of Fig. 4, the storage area is stored in the memory step so that the second range 52 is under the direction of the same direction and only enters the side of the door, and only the edge of the interrogation edge is performed. Image data processing, one side of the data processing is by - 佶 / South end edge 46c. Hunting is performed by binarization processing or the like. Thereafter, the control unit 60 #图*山, A, Huanhua & edge 46c "丄 C is stored in the memory 65. The control 60 error is stored in the memory 42 edge 42d, and the first edge 42c and the circumference 42e, 42fu are shown in steps S1 to 8 to scan the periphery 42e, 42f of the scanning edge 42c.

Next, as shown in step S11 of Fig. 4, the detection of the poles extending in the same direction as the direction in which the bow legs 46 extend is performed by edge detection. As shown in step S111 of Fig. 4, the control unit 6 stops the scanning after detecting the two electrodes 42a and 42b, and stores the positions of the two electrode cores 4b in the memory 65. The process P 60 is as shown in step sii 2 of Fig. 4, reading the position of the electric and a, 42b from the memory ^ and the edge of the pin, the position of the shirt, and calculating 16 201103095 2 adjacent electrode edge 42a and lead The distance 46 between the pin 46 of the leg edge 46a is a distance B from the right angle direction (Y direction), 嚷铋MU M, and the distance B between the electrode edge 42b and the pin edge. Next, the positional shift amount of the electrode 42 and the lead 46 which is the difference between the distance VIII and the distance B is stored in the memory... control unit 60, as shown in step Slu of FIG. 4, multiplying the obtained offset by For example, a factor of 1/2 or the like is used to calculate the correction amount. Next, as shown in step SU4 of Fig. 4, the correction position is corrected in accordance with the correction amount "the direction in which the extending direction is straight: the direction (Y direction). The correction of the bonding position is performed as described in the embodiment. When the processing is fixed to the image captured by the camera, the image is aligned, and the offset of the center of the other camera and the position of the joint can be changed by the amount of correction to move the joint to the position of 12. The coordinates of the joint position can be directly corrected and the center of the bonding tool 12 can be moved to the correction coordinate to be joined. The embodiment of the present invention described above is limited to the processing of image data by the edges 42a to 42d of the detecting electrode 42. The range of the image processing can therefore increase the speed of the image processing. Therefore, as shown in FIG. 1 , the electrode 42 and the bow which have been joined according to the tape body 45 in the time of being fixed to the bonding stage 由于 can be used for the bonding of a semiconductor wafer. The positional deviation of the leg 46 calculates the correction amount of the engagement position, so that the engagement state of the electrode 42 and the lead 46 can be detected and monitored without stopping the engagement operation. Therefore, the bonding quality can be improved without lowering the operational efficiency of the bonding apparatus 100. Further, the control unit 60 can calculate the offset between the electrode 42 and the pin 46 for a plurality of semiconductor wafers at a plurality of locations. The amount is multiplied by the average value to calculate the correction amount. The offset amount 17 201103095 can also be calculated for a plurality of semiconductor wafers. The value is stored in the memory 65'. After the (four) times are joined, the average value is calculated.
