Abstract:
A semiconductor manufacturing equipment for detaching each semiconductor chip from a dicing sheet by attracting each said chip with a collet, after a semiconductor wafer bonded to said dicing sheet is diced and separated into a plurality of said semiconductor chips still held on said dicing sheet, said collet having a collet body, said collet body comprising:an attraction surface for attracting each said chip; and a recess provided in said attraction surface so that said chip be attracted when said recess is reduced in pressure to a negative value relative to the atmospheric pressure, wherein said collet body is made as a block having a plane serving as said attraction surface, said recess containing deformation preventing elements to locate top surfaces or apexes of said deformation preventing elements in the same level as said attraction surface of said block so that said deformation preventing elements prevent each said chip from bending toward the depth direction of said recess.
