发明名称 Methods to achieve precision alignment for wafer scale packages
摘要 Methods for manufacturing an integrated wafer scale package that reduces a potential misalignment between a chip and a pocket of a carrier substrate. According to one aspect of the present invention, a method for manufacturing a semiconductor device includes a photoresist layer disposed on a carrier substrate, a chip placed onto a surface of the photoresist layer. The photoresist layer is patterned using the chip as a mask. The chip is removed from the photoresist layer after the patterning step. A pocket is formed in the carrier substrate, and the chip that was removed is placed into the pocket formed in the carrier substrate.
