Abstract

PURPOSE: To avoid the pushed flaws and the defective electrical characteristics of a chip created in post-processes by a method wherein suction holes are provided near the contact part of a collet where the collet is brought into contact with the circumference of the chip.
CONSTITUTION: A number of suction holes 8 which are linked with an exhaust hole 6 through a shut valve 9 are arranged radially near and outside the contact part 7 of a collet 2a where the collet 2a is brought into contact with the circumference of a chip 1. In order to remove the chip 1 from an adhesive sheet 4 with this chip removing jig, when the collet 2a is made to approach the chip 1, the shut valve 9 is opened and wastes adhering to the surface of the chip 1 are drawn off. When the collet 1 is brought into contact with the chip 1, the shut valve 9 is closed and the chip 1 is attracted by the collet 2a. With this constitution, the pushed flaws and the defective electrical characteristics of the chip can be avoided.
