Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of semiconductor processing, and in particular to a device which can quickly arrange a plurality of chips according to a certain rule and fix them on a chip carrier. Background Art
[0002] The existing technology for mass transfer of chips is to bump the chip from the raw material carrier film to the highest point, and then the chip is sucked by the suction nozzle and sent to the pre-arranged carrier plate. Various methods for transferring chips to the substrate have appeared in this field, and the more common one is the suction nozzle swing arm structure. The stability during the transfer process determines the actual operational feasibility of the production capacity. The stability of the transfer refers to the probability of accurate placement, skewness, flipping, and missing of the chip under high-speed operation. Whether these occur or not will directly affect the success or failure of the transfer. Therefore, the operating speed is limited under the supervision of the yield rate and cannot be changed through slight adjustments. The existing technology cannot maintain stability and improve the yield rate during high-speed chip transfer. Summary of the invention
