Abstract:
1. A method for manufacturing semiconductor chips by dividing a semiconductor wafer, on which a circuit is formed in each of plural regions divided by streets, into semiconductor chips for individual circuits, said method comprising: integrating a support plate with a semiconductor wafer by sticking a front face of the semiconductor wafer to the support plate via an adhesive sheet that includes a gas-generating agent which, upon stimulation, generates a gas to lower an adherence of the adhesive sheet; grinding a rear face of the semiconductor wafer integrated with the support plate; dicing the semiconductor wafer, ground and integrated with the support plate, from the rear face of the semiconductor wafer into semiconductor chips; and separating the semiconductor chips from the support plate by applying stimulation to cause generation of gas by the gas-generating agent to lower the adherence of the adhesive sheet.
