Abstract
Description
[Technical field]
[0001] The present invention relates to a die peeling method. [Background technology]
[0002] Integrated circuits are fabricated on a semiconductor wafer through multiple steps in batch production, and the wafer is then cut into multiple dies. In other words, a die is a small, unpackaged integrated circuit body made of semiconductor material. The cut dies are then systematically attached to multiple target areas on a carrier film. Then, a long and thin pick-up rod is used to break through the carrier film, press and move the target die, and the target die is peeled off from the target area on the carrier film. Finally, a pick-up device transfers the target die from the carrier film onto a substrate for subsequent processing steps.

The present invention provides a die peeling method, which includes the steps described below.
[0019] In step S100, as shown in Figures 1A and 2, a supporting device 10 supports a carrier film 20, and an annular body 30 abuts against the carrier film 20, and multiple dies 40 having solder balls and no copper pillars on their surfaces are distributed on the upper surface of multiple target areas of the carrier film 20.
[0020] In step S110, as shown in FIG. 1A and FIG. 3, the annular body 30 is raised and the carrier film 20 is expanded to increase the width of the gaps 41 between the multiple dies 40.
[0021] 1A and 3, in step S120, an image 51 of at least one target die 42 and at least one adjacent die 43 is captured by an image capture unit 50, as shown in FIG. 4. The at least one target die 42 is positioned on the top surface of the target area 21 of the carrier film 20, and the at least one adjacent die 43 is positioned on the top surface of the adjacent area 22 of the carrier film 20.
[0022] 1A and 4, in step S130, referring to FIG. 3, the processing unit 60 receives an image 51 and determines whether or not the gap 41 between at least one target die 42 and at least one adjacent die 43 is aligned with the gap 73 between the first suction device 71 and the second suction device 72 of the base 70 based on the image 51. If the processing unit 60 determines that the gap 41 is aligned with the gap 73 based on the image 51, the process proceeds to the next step, and if the processing unit 60 determines that the gap 41 is not aligned with the gap 73 based on the image 51, the process ends.
[0023] In step S140, as shown in Figures 1B and 5, referring to Figure 4, if the processing unit 60 determines based on the image 51 that the gap 41 between at least one target die 42 and at least one adjacent die 43 is aligned with the gap 73 between the first suction device 71 and the second suction device 72 of the base 70, the base 70 is raised until the first suction device 71 abuts against the bottom surface of the target area 21 and the second suction device 72 abuts against the bottom surface of the adjacent area 22.
[0024] In step S150, as shown in Figures 1B and 6, a first suction device 71 generates negative pressure 74 to suction and hold the target area 21 immobile, a second suction device 72 suctions the adjacent area 22 by the negative pressure 74, and the second suction device 72 is driven and lowered by a driving device 75, and the adjacent area 22 is suctioned and lowered by the negative pressure 74 of the second suction device 72, thereby forming a step 23 between the target area 21 and the adjacent area 22, and at least one target die 42 is peeled off from the top surface of the target area 21 by the step 23.
[0025] In step S160, as shown in FIGS. 1B and 7, the first suction device 71 stops suctioning the target area 21 by the negative pressure 74, the second suction device 72 stops suctioning the adjacent area 22 by the negative pressure 74, the target area 21 is detached from the first suction device 71, and the adjacent area 22 is detached from the second suction device 72; at least one target die 42 is suctioned by the die fixing device 80, and the at least one target die 42 is placed on a substrate 90 having solder balls and copper pillars on its surface.
[0026] Two aspects of a first embodiment of the method according to the invention will now be described with reference to the drawings.
[0027] 8 is a top view of the first embodiment of the method according to the present invention. As shown in FIG. 8, for the first embodiment, the at least one target die 42 is a single target die 42, and the at least one adjacent die 43 is a single adjacent die 43. More specifically, in step S120, an image 51 of the single target die 42 and the single adjacent die 43 is captured by an image capture unit 50; in step S130, the image 51 is received by a processing unit 60, and based on the image 51, a gap 41 between the single target die 42 and the single adjacent die 43 is determined to be aligned with a gap 73 between the first suction device 71 and the second suction device 72 on the base 70; in step S150, the single target die 42 is peeled off from the top surface of the target area 21.
[0028] 9 is a top view of a second embodiment of the first embodiment of the method according to the present invention. As shown in FIG. 9, for the second embodiment, the at least one target die 42 is a plurality of target dies 42 in one row of a plurality of rows of die combinations 44, and the at least one adjacent die 43 is a plurality of adjacent dies 43 in another row of the plurality of rows of die combinations 44.
[0029] More specifically, in step S100, the plurality of dies 40 are arranged into a plurality of rows of die combinations 44, each of which includes a plurality of dies 40; in step S120, an image capture unit 50 captures an image 51 of a plurality of target dies 42 in one row of the plurality of rows of die combinations 44 and a plurality of adjacent dies 43 in another row of the plurality of rows of die combinations 44; in step S130, a processing unit 60 receives the image 51 and determines based on the image 51 whether the gaps 41 between the plurality of target dies 42 in one row of the plurality of rows of die combinations 44 and the plurality of adjacent dies 43 in another row of the plurality of rows of die combinations 44 are aligned with the gaps 73 between the first suction device 71 and the second suction device 72 on the base 70; in step S150, the plurality of target dies 42 in one row of the plurality of rows of die combinations 44 are peeled off from the top surface of the target area 21.
[0030] Apparently, the number of dies 40 that can be processed at one time in the second embodiment is greater than that in the first embodiment, and the efficiency is higher.
[0031] 10 is a schematic diagram of the connection relationship between the first suction device 71, the second suction device 72, and the vacuum device 100 in the present invention. As shown in FIG. 2 and FIG. 10, preferably, the first suction device 71 is provided with a plurality of first channels 711, the second suction device 72 is provided with a plurality of second channels 721, and the plurality of first channels 711 and the plurality of second channels 721 are connected to the vacuum device 100.
[0032] In step S150, as shown in Figures 6 and 10, when the vacuum device 100 synchronously extracts gas from the first channels 711 and the second channels 721, the gas in the first channels 711 and the second channels 721 is discharged to the outside to create a vacuum state, and at the same time, negative pressure is provided, so that the first adsorption device 71 adsorbs the target area 21 by the negative pressure 74, and the second adsorption device 72 adsorbs the adjacent area 22 by the negative pressure 74.
[0033] In step S160, as shown in Figures 7 and 10, when the vacuum device 100 stops synchronously extracting air from the first channels 711 and the second channels 721, the first channels 711 and the second channels 721 are released from the vacuum state, and since the vacuum device 100 does not provide negative pressure 74, the first suction device 71 stops adsorbing the target area 21 by the negative pressure 74, and the second suction device 72 stops adsorbing the adjacent area 22 by the negative pressure 74.
[0034] Figures 11A and 11B are flowcharts of a second embodiment of the method according to the present invention, Figure 12 is a schematic diagram of step S240 of the second embodiment of the method according to the present invention, Figure 13 is a schematic diagram of step S250 of the second embodiment of the method according to the present invention, Figure 14 is a schematic diagram of step S260 of the second embodiment of the method according to the present invention, Figures 15A and 15B are schematic diagrams of a first and second embodiment, respectively, of step S270 of the second embodiment of the method according to the present invention, and Figure 16 is a schematic diagram of step S280 of the second embodiment of the method according to the present invention.
[0035] As shown in Fig. 11A, steps S200 to S230 of the second embodiment are exactly the same as steps S100 to S130 of the first embodiment. As shown in Fig. 11B, 12 and 13, steps S240 to S250 of the second embodiment are different from steps S140 to S150 of the first embodiment in that at least one target die 42 is adsorbed by the die fixing device 80. After step S250 of the second embodiment, the following steps are further included.
[0036] Specifically, as shown in FIGS. 10, 11B and 14, when at least one target die 42 is adsorbed by the die fixing device 80 and the vacuum device 100 stops synchronously extracting air from the first channels 711 and the second channels 721, the first channels 711 and the second channels 721 are released from the vacuum state, and since the vacuum device 100 does not provide negative pressure 74, the first adsorption device 71 stops adsorbing the target area 21 by the negative pressure 74, and the second adsorption device 72 stops adsorbing the adjacent area 2 by the negative pressure 74. 11B, 15A, and 15B, the die fixing device 80 fixes at least one target die 42, and moves the base 70 laterally (see FIG. 15A, which is a first embodiment) or moves the carrier film 20 laterally (see FIG. 15B, which is a second embodiment) to reduce the gap 73 between the first suction device 71 and the second suction device 72. 10, 11B and 16, at least one target die 42 is adsorbed by a die fixing device 80, and a vacuum device 100 synchronously bleeds the first channels 711 and the second channels 721, so that the gas in the first channels 711 and the second channels 721 is exhausted to the outside to generate a vacuum state, and at the same time, a negative pressure 74 is provided, so that the first adsorption device 71 adsorbs the target area 21 by the negative pressure 74, and the second adsorption device The method further includes a step S280 of adsorbing the adjacent area 22 by using negative pressure 74, driving the second adsorption device 72 by a driving device 75 to lower the second adsorption device 72, adsorbing and lowering the adjacent area 22 by the negative pressure 74 of the second adsorption device 72, thereby forming a step 23 between the target area 21 and the adjacent area 22, and expanding the area in which at least one target die 42 is peeled off from the target area 21 by the step 23, and a step of repeatedly performing the above-mentioned steps until the at least one target die 42 is completely detached from the upper surface of the target area 21.
[0037] As shown in FIG. 10B, step S290 in the second embodiment is exactly the same as step S160 in the first embodiment.
[0038] In the five steps from step S240 to step S280, the die fixing device 80 continues to adsorb the at least one target die 42, so that the alignment with the at least one target die 42 can be continuously maintained and the at least one target die 42 is not displaced due to the influence of the lateral movement of the pedestal 70. Therefore, the range in which the at least one target die 42 is peeled off from the target area 21 can be gradually expanded.
[0039] Since the bottom surface of the at least one target die 42 is completely separated from the top surface of the target area 21 , the at least one target die 42 can be easily transferred to the substrate 90 by the die fixing device 80 .
[0040] The difference between the first embodiment of the second embodiment and the first embodiment of the first embodiment is that in the six steps from step S240 to step S290, a single target die 42 is continuously adsorbed by a single die fixing device 80. The difference between the second embodiment of the second embodiment and the second embodiment of the first embodiment is that in the six steps from step S240 to step S290, a plurality of die fixing devices 80 are arranged in a row, and each of the plurality of target dies 42 in one row of the plurality of rows of die combinations 44 is continuously adsorbed.
[0041] As described above, the method according to the present invention makes it possible to peel the target die 42 from the carrier film 20 without destroying the carrier film 20 or contacting the target die 42, thereby avoiding damage to the carrier film 20 and the target die 42. This allows the carrier film 20 to be used repeatedly, and also improves the production yield of the dies 40.
[0042] The above-mentioned are only preferred embodiments for explaining the present invention, which are not intended to impose any formal limitations on the present invention, and any modifications or changes made to the present invention under the same inventive concept should be included in the intended scope of protection of the present invention.
