Abstract:
1. A method for manufacturing a semiconductor device, comprising: forming a separation layer on a supporting substrate; forming a wiring layer having a plurality of device forming areas and dicing areas on the separation layer; mounting a plurality of semiconductor chips on the wiring layer such that the semiconductor chips are disposed on the plural device forming areas respectively; forming a sealing resin layer covering the plural semiconductor chips on the wiring layer to obtain a resin-sealed body having the wiring layer and the plural semiconductor chips; separating the resin-sealed body from the supporting substrate; and cutting the resin-sealed body according to the dicing areas to singulate a circuit structure body provided with the wiring layer, the semiconductor chip and the sealing resin layer, wherein, when the resin-sealed body is separated from the supporting substrate, or after the resin-sealed body is separated from the supporting substrate, the resin-sealed body is heated while being evenly held by a holder as a whole, and wherein the resin-sealed body is cooled while a state of the resin-sealed body being held evenly by the holder is maintained, and then a holding state of the resin-sealed body by the holder is released.
