Technical Field

[0001] The utility model relates to the technical field of semiconductor wafer processing, and particularly relates to a semiconductor wafer automatic processing device. Background Art

[0002] A semiconductor wafer generally refers to a silicon wafer used for manufacturing semiconductor silicon integrated circuits. Because of its circular shape, it is called a wafer. Due to the requirements of manufacturing processes, there are high requirements for the dimensional accuracy, geometric accuracy, surface cleanliness, etc. of the wafer. In these process flows, wafers of a certain thickness need to be transferred during the process. The specific steps are as follows: the semiconductor wafer is first thinned and then laminated, and then sliced into the required size. Subsequently, the semiconductor wafer can be placed on a semiconductor carrier frame.

[0003] In the existing film laminating mechanism of the automatic processing device, basically, manual pulling of the blue film is relied on to attach the semiconductor wafer. However, manual pulling may cause deformation due to uneven stress on both sides of the blue film end, resulting in wrinkling and damage during the subsequent attachment process. Secondly, after each film pulling and laminating, the operator also needs to cut and discard the used waste film. The process is complex and has a certain damage rate, thus leading to low efficiency of wafer film lamination. Therefore, this application provides a semiconductor wafer automatic processing device to meet the requirements. Summary of the Utility Model

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above solution, by setting up a film pressing protection mechanism, the staff can hold and open the pressing frame by using the mobility of the rotating hinge and the rotating frame. Then, the dried semiconductor wafer is placed in the cutting ring groove. Next, the staff can start the third motor and the fifth motor simultaneously. The third motor can drive the second transmission screw rod to rotate. At this time, the second screw sleeve interacting with the screw rod will drive the fixed frame and the rotating rod mounted in the middle of it to cooperate with the guiding rod to conduct film pulling treatment. The film is one end of the blue film outside the film roller. The fifth motor installed at one end of the film roller needs to be started to cooperate with the relaxation of the blue film. During the process of the rotating rod cooperating with the transmission to stretch the blue film, the air jet frame installed at the front end of the fixed frame can perform secondary cleaning on the dust and impurities that may remain above the semiconductor wafer. When the film pulling length is appropriate, the staff can hold the guide plate and move it along the direction of the pulled film. Since a scraping plate connected by a telescopic rod and a return spring is provided below the guide plate, the scraping plate can further flatten the fit between the blue film and the semiconductor wafer along the surface of the blue film to avoid the appearance of wrinkles and unevenness. Next, the staff closes the pressing frame and starts the second electric push rod to make the cutting knife connected to its bottom end descend to cut the blue film along a part of the cutting ring groove. After cutting, when the fixed frame and the rotating rod return to their original positions, the staff starts the fourth motor connected to one end of the rotating rod, so that the rotating rod can wind up and tighten the blue film that has just been used to avoid the appearance of scattered damage. Subsequently, the staff can take out the semiconductor wafer with the film pasted on it, and the dicing component in the dicing machine body can perform dicing treatment on the semiconductor wafer.

[0018] By setting up a thinning mechanism, the staff first places the semiconductor wafer to be processed in the placement area of the processing area in the middle of the thinning machine body. Then, two first electric push rods are started, so that the clamping blocks connected to the ends of the two push rods can effectively clamp and stabilize the two sides of the semiconductor wafer. Subsequently, the hydraulic push rod is started to lower the assembly frame. During this process, the staff starts the first motor inside the assembly frame, and under the transmission of the transmission rod, the grinding wheel performs surface thinning treatment on the clamped semiconductor wafer.

[0019] By setting up a cleaning mechanism, during the process of the grinding wheel thinning the semiconductor wafer, a large amount of dust and impurities are generated, and some of them will accumulate on the upper surface of the semiconductor wafer. After processing, the staff can start the second motor to make the first transmission screw rod rotate. At this time, the first screw sleeve interacting with the screw rod will drive the mounting frame to perform a lateral displacement in cooperation with the guiding of the sliding mounting frame. Since a water tank is provided above the mounting frame, the staff can start the water pump during the movement of the mounting frame. Under the guidance of the first connecting pipe and the second connecting pipe, the water in the water tank will be sprayed out from the spray washing frame, and the upper surface of the semiconductor wafer can be comprehensively washed in sequence in cooperation with the movement of the mounting frame. Immediately afterwards, the staff starts the heater to transfer the heat to the heating pipe rack, and in cooperation with the two operating blowers, the heat can be led to the surface of the semiconductor wafer that has just been cleaned, so as to achieve the effect of auxiliary drying and provide convenience for subsequent film pasting.

[0038] Such as Figures 1 to 7As shown in the figure, the film pressing protection mechanism 7 includes a rotating frame 71, and the rotating frame 71 is installed on one side of the top of the film pressing machine body 6. A rotating hinge 72 is movably arranged around the rotating frame 71, and a pressing frame 73 is fixed on one side of the rotating hinge 72. Loading boxes 74 are fixed on both sides of the top of the film pressing machine body 6, and a film loading roller 75 is installed on one side of the top of the film pressing machine body 6. A blue film 76 is sleeved around the film loading roller 75. Film pressing components 77 are installed inside and outside the two loading boxes 74. The film pressing component 77 includes a second transmission screw rod 771, and the second transmission screw rod 771 is installed inside one of the loading boxes 74. One end of the second transmission screw rod 771 is connected and installed with a third motor 772, and a second screw sleeve 773 is screwed on the periphery of one side of the second transmission screw rod 771. A fixed mounting frame 774 is fixed inside the second screw sleeve 773, and a fourth motor 775 is installed in the middle of one side of the fixed mounting frame 774. The output end of the fourth motor 775 is connected with a loading rotating rod 776. A guiding rod 777 is fixed inside the other loading box 74.

A film smoothing component 79 is installed inside the two loading boxes 74.

A return spring 794 is sleeved around the telescopic rod 793, and one end of the telescopic rod 793 is connected with a scraping and smoothing plate 795. The two ends of the return spring 794 are respectively connected with the guiding plate 792 and the scraping and smoothing plate 795. A reserved ring groove 710 is opened on one side of the top of the film pressing machine body 6, and a cutting ring groove 711 is opened around the reserved ring groove 710. A second electric push rod 712 is installed at the top of the pressing frame 73, and a cutting ring knife 713 is connected to the extending end of the second electric push rod 712. The staff holds and opens the pressing frame 73 by using the mobility of the rotating hinge 72 and the rotating frame 71, and then places the above-mentioned dried semiconductor wafer in the cutting ring groove 711. Then, the staff can start the third motor 772 and the fifth motor 778 synchronously. Among them, the third motor 772 can drive the second transmission screw rod 771 to rotate. At this time, the second screw sleeve 773 interacting with the screw rod will drive the fixed mounting frame 774 and the loading rotating rod 776 in the middle of it to cooperate with the guiding of the guiding rod 777 to perform film pulling treatment. The film belongs to one end of the blue film 76 outside the film loading roller 75. The fifth motor 778 arranged at one end of the film loading roller 75 needs to be started to cooperate with relaxing the blue film 76. During the process of the loading rotating rod 776 cooperating with the transmission to stretch the blue film 76, the air jet frame 78 arranged at the front end of the fixed mounting frame 774 can perform secondary cleaning on the dust and impurities that may be left above the semiconductor wafer.

Next, the operator closes the pressing frame 73 and starts the second electric push rod 712 to lower the cutting ring knife 713 connected to its bottom end to cut the blue film 76 along a part of the cutting ring groove 711. After the cutting is completed, when the fixing frame 774 and the carrying rotating rod 776 return to their original positions, the operator starts the fourth motor 775 connected to one end of the carrying rotating rod 776, so that the carrying rotating rod 776 can wind up and tighten the just-used blue film 76 to avoid the phenomenon of scattering and damage. Subsequently, the operator can take out the semiconductor wafer with the film attached, and the dicing component in the dicing machine body 8 can perform dicing on the semiconductor wafer.,

[0039] The working principle of the technical solution provided by the present utility model is as follows:

[0040] The staff pre - places the semiconductor wafer to be processed in the placement area 412 of the processing area 2 in the middle of the wafer thinning machine body 1. Then, two first electric push rods 413 are started, so that the clamping blocks 414 connected to the ends of the two push rods can effectively clamp and stabilize the two sides of the semiconductor wafer. After that, the hydraulic push rod 421 is started to lower the assembly frame 422. During this process, the staff starts the first motor 423 inside the assembly frame 422. Driven by the transmission rod 424, the grinding wheel 425 performs surface thinning treatment on the clamped semiconductor wafer. Secondly, during the thinning process of the grinding wheel 425 on the semiconductor wafer, a large amount of dust and impurities are generated, and some of them will accumulate on the upper surface of the semiconductor wafer. After the processing is completed, the staff can start the second motor 52 to rotate the first transmission lead screw 51. At this time, the first lead screw slider 53 interacting with the lead screw will drive the mounting frame 54 to move horizontally in cooperation with the guidance of the sliding mounting frame 55. Since there is a water tank 561 above the mounting frame 54, the staff can start the water pump 563 during the movement of the mounting frame 54. Under the guidance of the first connecting pipe 562 and the second connecting pipe 564, the water in the water tank 561 will be sprayed out from the spray washing frame 565, and the upper surface of the semiconductor wafer can be washed comprehensively in sequence with the movement of the mounting frame 54. Immediately afterwards, the staff starts the heater 566, so that the heat is transmitted to the heating pipe rack 567. Cooperating with the two operating blowers 568, the heat can be led to the surface of the semiconductor wafer that has just been cleaned, so as to achieve the effect of auxiliary drying, providing convenience for subsequent film sticking. Finally, the staff uses the mobility of the rotating hinge 72 and the rotating frame 71 to manually open the pressing frame 73. Then, the dried - up semiconductor wafer is placed in the cutting ring groove 711. Then, the staff can start the third motor 772 and the fifth motor 778 synchronously. Among them, the third motor 772 can drive the second transmission lead screw 771 to rotate. At this time, the second lead screw slider 773 interacting with the lead screw will drive the fixed mounting frame 774 and the rotating rod 776 in the middle to perform film pulling treatment in cooperation with the guidance of the guiding rod 777. The film belongs to one end of the blue film 76 outside the film loading roller 75. The fifth motor 778 provided at one end of the film loading roller 75 needs to be started to cooperate with the relaxation of the blue film 76. During the process of the rotating rod 776 cooperating with the transmission to stretch the blue film 76, the air jet frame 78 provided at the front end of the fixed mounting frame 774 can perform secondary cleaning on the dust and impurities that may remain above the semiconductor wafer. When the film pulling length is appropriate, the staff can hold the guide plate 792 and move it along the direction of the pulled film. Since there is a scraping plate 795 connected by a telescopic rod 793 and a return spring 794 below the guide plate 792, the scraping plate 795 can further flatten the fit between the blue film 76 and the semiconductor wafer along the surface of the blue film 76, avoiding the appearance of wrinkles and unevenness. Next, the staff closes the pressing frame 73 and starts the second electric push rod 712 to lower the cutting ring knife 713 connected to its bottom end to cut the blue film 76 along a part of the cutting ring groove 711. After the cutting is completed, when the fixed mounting frame 774 and the rotating rod 776 return to their original positions,The operator starts the fourth motor 775 connected to one end of the carrying rod 776, so that the carrying rod 776 can wind and compact the just-used blue film 76 to avoid scattering and damage. Subsequently, the operator can take out the semiconductor wafer with the film pasted on it, and the dicing component in the dicing machine body 8 can perform dicing on the semiconductor wafer.
