Abstract:
1. A method for producing an IC chip that is manufactured by bonding a surface of a chip portion to a reinforcing plate, comprising: forming a wafer on which a plurality of said chip portions are two-dimensionally arranged, and on which a plurality of surrounding portions that surround the chip portions are arranged, the surrounding portions being thinner than the chip portions; forming grooves two-dimensionally in said reinforcing plate; and bonding said wafer and said reinforcing plate together using a method for bonding the wafer having a first adhesion surface and a first back surface and the reinforcing plate having a second adhesion surface and a second back surface by an adhesive, the adhesive being sandwiched between said first adhesion surface and said second adhesion surface, the bonding comprising: dicing a combination of said wafer and said reinforcing plate that are bonded into IC chips, said combination being diced along said grooves, wherein the temporarily bonding the wafer and the reinforcing plate comprises:
