Patent ID: 6939741

Claim:
A method for manufacturing an IC chip comprising, at least: the step of securing a wafer to a support plate via a support tape having a surface layer comprising an adhesive (A) containing a gas generating agent for generating a gas due to stimulation and a surface layer comprising an adhesive (B); the step of polishing said wafer with securing said wafer to said support plate via said support tape; the step of adhering a dicing tape to said polished wafer; the step of providing said stimulation to said adhesive (A) layer; the step of removing said support tape from said wafer; and the step of dicing said wafer, which comprises adhering said surface layer comprising adhesive (A) to said wafer and adhering said surface layer comprising adhesive (B) to said support plate in the step of securing said wafer to said support plate via said support tape, providing said stimulation while uniformly sucking under reduced pressure the entirety of said wafer from the dicing tape side thereof, and then removing said support tape from said wafer in the step of providing stimulation to said adhesive (A) layer and in the step of removing said support tape from said wafer.
