Description
Technical Field
[0001] The present application relates to the field of chip processing, and in particular to a semiconductor chip processing device and method. Background Art
[0002] There are solder balls installed on the chip. The solder balls are mainly used to connect the chip's pads with the package substrate to achieve signal transmission and power supply between the chip and the external circuit. The solder balls can also play a role in heat dissipation and provide support for the chip to keep it stable during the packaging process and reduce the damage to the chip caused by external impact.
[0003] The existing chip installation solder ball operations usually include: screen printing, laser ball planting, etc. Screen printing prints solder paste onto the substrate pad through a steel mesh template, and reflow soldering heats the solder paste to a molten state, forming a spherical shape under the action of surface tension. Laser ball planting is to store the prepared solder balls in the machine, transport the solder balls to the designated position of the pad through N2, and then use a laser to heat the solder balls. After the solder balls are cooled, the chip is firmly combined. Among the above methods, although the printing method has low cost, it is difficult to install small solder balls and the uniformity is poor. Laser installation is inefficient and costly.

[0036] On the other hand, the present application also discloses a semiconductor chip processing method, which adopts the following technical solution:
[0037] A semiconductor chip processing method, comprising any one of the above processing equipment, further comprising the following steps: material preparation: placing a plurality of chips into a material tray in sequence, and arranging the surface to be installed with solder balls facing upward, and then placing the filled material tray into a material box, and a plurality of grooves for positioning the material tray are provided on both sides of the material box, and when the material box is full, the material box is placed on a feeding device, and the feeding device feeds the material;
[0038] Feeding: After the feeding device transports the material tray to the discharge end, the transfer device receives the material box on the feeding device, and the transfer device aligns the open end of the material box with the receiving device. The receiving device takes out the material tray in the material box and then places it on the conveying device;
[0039] Material inspection: After the receiving device places the chip on the conveying device, the adjusting device first adjusts the position of the chip in the tray to ensure the uniformity of the chip position. After the adjusting device completes the adjustment, the conveying device conveys the tray to the bottom of the detection device for position detection. The detection device detects the chip position to check whether there is an error in the chip position. If the chip position is incorrect, the adjusting device adjusts it again; if the chip position is correct, the conveying device transfers the tray to the next processing point;
[0040] Apply solder paste: The conveyor conveys the material tray (the chips in the material tray are all adjusted in position) to the working area of the coating device, the coating device moves to a place of the material storage device, moves down to dip in the solder paste, and then moves to the conveyor and applies the solder paste to the material tray on the conveyor. The coating device applies the solder paste to the groove of the chip; after the coating device is finished, the excess solder paste needs to be scraped off and then dipped again;
[0041] Install solder balls: The conveying device conveys the chip coated with solder paste to the installation area of the adsorption device, and the storage device 2 places the solder balls in the vibration device. The vibration device disperses the solder balls by vibration, and the adsorption device moves to the top of the vibration device to adsorb the solder balls. The solder balls are adsorbed into the adsorption tank through vacuum. After the adsorption device completes the adsorption, the adsorption device moves to the cleaning device, and the cleaning device removes the excess solder balls at the adsorption end of the adsorption device. After the cleaning is completed, the adsorption device moves to the detection device 2 for detection. The detection device 2 mainly detects whether the solder balls adsorbed on the adsorption device are complete. If the detection device 2 detects that the solder balls on the adsorption device are not completely adsorbed, the adsorption device will be re-adsorbed. It returns to the vibration device to adsorb the solder balls, and then passes through the cleaning device to clean it again, and passes through the detection device 2 to detect that it passes the detection, and moves to the conveying device. If it fails the detection, the above adsorption, cleaning and detection operations are repeated; if the detection device 2 detects that there is a problem with the quality of the solder balls on the adsorption device, a material tray for loading the problematic solder balls is installed, and the adsorption device moves to the material tray, and the problematic solder balls are placed in the material tray, and then the adsorption device adsorbs the solder balls again, and passes through the cleaning device to clean it, and passes through the detection device 2; if the detection device 2 detects that the adsorption of the solder balls on the adsorption device is intact, it moves directly to the conveying device and installs the solder balls in the grooves of the chip;
[0042] Discharging: After the solder balls are installed on the chip, the conveying device conveys the chip to the discharging end, where it is inspected by the detection device three. The material tray through which the chip is detected is moved to the discharging device by the material transfer device two. When the detection device three detects the material tray with the problematic chip, the material transfer device two transfers the material tray to the collection device, which is then recycled and processed by the staff.
[0043] To sum up, the feeding device, transfer device, material receiving device and conveying device can effectively improve the material conveying efficiency, improve the overall material processing efficiency, reduce the number of manual handling times, and reduce the manual handling cost; the adjusting device can improve the position uniformity of subsequent material processing, thereby improving the material processing quality; the detection device one, the detection device two and the detection device can improve the material processing quality, ensure the quality and efficiency of the material installation of solder balls, and save the material processing cost; the adsorption device can improve the installation efficiency of solder balls; the cleaning device and the detection device two can improve the quality of the solder balls installed by the adsorption device, and ensure the installation integrity of the solder balls.

[0077] The implementation principle of a semiconductor chip processing device in the embodiment of the present application is as follows: the feeding device 2 is used to convey materials and also serves as a material storage device. Multiple groups of materials can be placed on the feeding device 2. When the equipment is in operation, the conveyor belt 23 can feed the materials in sequence. The transfer device 3 receives the materials on the feeding device 2 and aligns the materials with the discharge end of the receiving device 4, so that the receiving device 4 can receive the materials. After receiving the materials, the receiving device 4 transfers the materials to the conveying device 5. After the materials are placed, they continue to return to the feed end to receive the materials.
[0078] The material on the conveyor 5 first needs to be adjusted in position. The adjustment device 6 adjusts the position of the material on the conveyor 5 to ensure the uniformity of the subsequent processing position of the material and improve the accuracy of subsequent operations. After the adjustment of the adjustment device 6 is completed, the detection device 7 detects whether the adjusted position of the material is intact. At this time, there are two results: 1. There is still a deviation in the position of the material. At this time, the conveyor 5 returns the material to the adjustment device 6 for position adjustment, and continues to detect after adjustment; 2. The material position is adjusted intact, and the conveyor 5 directly transfers the material to the next processing node. In order to save adjustment time and improve overall processing efficiency, multiple groups of conveyor 5 are set to speed up the transmission efficiency and shorten the waiting time of subsequent steps.
[0079] The conveying device 5 conveys the material that has passed the inspection to the processing node for applying solder paste. The applying device 9 moves to the storage device 8 to dip the solder paste, and then moves to the conveying device 5, moves down to dip the solder paste on the surface of the material. Then the applying device 9 returns to the storage device 8. Before returning, the applying device 9 needs to dip the excess solder paste on the applying block 96 into the recovery device 20, and then perform the next dipping operation. Improve the subsequent application quality of solder paste, avoid excess solder paste overflow, and improve the chip processing quality.
[0080] After the material is coated with solder paste, solder balls need to be installed. The conveying device 5 conveys the material to the solder ball installation area. The adsorption device 12 moves to the front of the vibration device 11. The storage device 10 pours the solder balls into the vibration device 11. The vibration device 11 vibrates and disperses the solder balls. Then the adsorption device 12 moves to the top of the vibration device 11 to adsorb the solder balls. Through vacuum adsorption, after the solder balls enter the adsorption tank, the adsorption end of the adsorption tank is blocked by the solder balls, and the adsorption source is closed. At this time, the adsorption tank will not adsorb excess solder balls. Due to the small size of the solder balls, under the influence of static electricity, the excess solder balls will adhere to the bottom of the adsorption block 126. At this time, the excess solder balls need to be cleaned up. The adsorption device 12 moves to the cleaning device 14 for cleaning. The cleaning device 14 vacuum adsorbs the excess solder balls through the long groove 1421. Since the excess solder balls are not positioned by the adsorption force of the adsorption tank, the long groove 1421 can easily clean the excess solder balls.
[0081] After the cleaning device 14 completes the cleaning, the adsorption device 12 moves to the detection device 13 for detection and processing to detect whether the several adsorption slots at the bottom of the adsorption block 126 are all adsorbed with solder balls. At this time, three situations may occur: 1. The detection passes, and the adsorption device 12 moves directly to the top of the material of the conveying device 5 to discharge the material; 2. The detection fails. The reason for the failure is that the adsorption is not complete, and some adsorption slots are empty. At this time, the adsorption device 12 moves to the vibration device 11 for re-supplementation of adsorption. After adsorption, it moves to the cleaning device 14 for cleaning, and the detection device 13 detects; 3. The detection fails. The reason for the failure is that there are quality problems with the solder balls, such as damage and deformation on the surface of the solder balls. The adsorption device 12 moves to the material tray 27, places the batch of solder balls in the material tray 27, and then returns to the vibration device 11 to adsorb a new batch of solder balls, and then performs the cleaning and detection operation process again.
[0082] The adsorption device 12 that passes the inspection directly installs the solder ball on the material of the conveying device 5. The conveying device 5 conveys the installed material to the detection device 3 15 for inspection to detect the quality of the material solder ball installation. At this time, there are two conditions: 1. The inspection passes, and the material is directly placed in the discharge device 17 by the material transfer device 16 for storage; 2. The inspection fails, and the material is moved to the collection device 18 by the material transfer device 16 for processing by the staff.
[0083] This application can install solder balls in batches to improve product processing efficiency; each node of this application is equipped with detection results to improve product processing quality, reduce the cost of manual inspection, save processing time, and improve production efficiency.

Several grooves for placing chips are evenly provided in the tray. The chips are placed in the grooves with the surface to be installed with solder balls facing upward. Then, the filled tray is placed in the material box. Several grooves for positioning the tray are provided on both sides of the material box. Multiple trays can be installed in the material box in sequence. When the material box is full, the material box is placed on the feeding device 2, and the feeding device 2 feeds the materials.
[0086] Feeding: After the feeding device 2 transports the material tray to the discharge end, the transfer device 3 receives the material box on the feeding device 2, and the transfer device 3 aligns the open end of the material box with the receiving device 4. The pushing component 28 pushes the material tray toward the receiving device 4, and then the receiving device 4 takes out the material tray and places it on the conveying device 5;
[0087] Material inspection: After the receiving device 4 places the chip on the conveying device 5, the adjusting device 6 first adjusts the position of the chip in the tray to ensure the uniformity of the chip position; after the adjusting device 6 completes the adjustment, the conveying device 5 conveys the tray to the bottom of the detection device 7 for position detection, and the detection device 7 detects the chip position to check whether there is any chip position error; if the detection fails, the conveying device 5 conveys it back to the adjusting device 6 for adjustment again; if the detection passes, the conveying device 5 transfers the tray to the next processing point;
[0088] Apply solder paste: the conveying device 5 conveys the material tray (the chips in the material tray are all adjusted in position) to the working area of the coating device 9, the coating device 9 moves to the material storage device 8, moves down to dip the solder paste, and then moves to the conveying device 5 and applies the solder paste to the material tray on the conveying device 5. The coating device 9 applies the solder paste to the groove of the chip; after the coating device 9 completes the coating, the coating device 9 moves to the recovery device 20, the coating block 96 moves down to dip the excess solder paste onto the contact plane 202, reduces the excess solder paste on the coating block 96, and then moves back to the material storage device 8 for re-dipping;
[0089] Install solder balls: The conveying device 5 conveys the chip coated with solder paste to the installation area of the adsorption device 12, and the storage device 10 places the solder balls in the vibration device 11. The vibration device 11 disperses the solder balls by vibration, and the adsorption device 12 moves to the top of the vibration device 11 to adsorb the solder balls. The solder balls are adsorbed into the adsorption tank by vacuum. After the adsorption device 12 completes the adsorption, the adsorption device 12 moves to the cleaning device 14, and the cleaning device 14 removes the excess solder balls at the adsorption end of the adsorption device 12. After the cleaning is completed;
[0090] Detection of solder ball adsorption quality: the adsorption device 12 moves to the detection device 13 for detection. The detection device 13 mainly detects whether the solder balls adsorbed on the adsorption device 12 are complete. First, if the detection device 13 detects that the adsorption of the solder balls on the adsorption device 12 is incomplete, the adsorption device 12 returns to the vibration device 11 to adsorb the solder balls, and is cleaned again by the cleaning device 14. The detection of the detection device 13 is passed. If the detection passes, it moves to the conveying device 5. If the detection fails, the above adsorption, cleaning and detection operations are repeated. Second, if the detection device 13 detects that there is a problem with the quality of the solder balls on the adsorption device 12, the detection device moves the adsorption device 12 to the excess material tray 27, places the problematic solder balls in the material tray 27, and then the adsorption device 12 re-adsorbs the solder balls, and then is cleaned by the cleaning device 14, and the detection of the detection device 13 is performed. Third, if the detection device 13 detects that the adsorption of the solder balls on the adsorption device 12 is intact, it moves directly to the conveying device 5 and installs the solder balls in the grooves of the chip.
[0091] Discharging: After the solder balls are installed on the chip, the conveying device 5 conveys the chip to the discharging end, where it is inspected by the detecting device 3 15. The material tray through which the chip is detected is moved by the material transfer device 16 2 to the discharging device 17. The detecting device 3 15 detects the material tray with the problematic chip, and the material transfer device 16 2 conveys the material tray to the collecting device 18, which is then recycled and processed by the staff.
