Method for manufacturing semiconductor chip

摘要

A semiconductor wafer (W) where circuits are formed in the area formed in the area divided by streets is split into semiconductor chips having an individual circuit. By interposing an adhesive sheet whose adhesive force is lowered by stimulation between the semiconductor wafer (W) and the support plate (13), the front side of the semiconductor wafer (W) is adhered to the support plate (13), exposing the rear face (10) of the semiconductor wafer (W). The rear face (10) of the semiconductor wafer (W) with the support plate (13) is ground. After the grinding is finished, the semiconductor wafer (W) is held with the rear face (10) up is diced into semiconductor chips (C). The adhesive sheet is given stimulus to lower the adhesive force and the semiconductor chips (C) are removed from the support plate (13). The semiconductor wafer and semiconductor chips are always supported by the support plate, avoiding damaging or deforming.
