Abstract:
1. A method for manufacturing a semiconductor device, comprising the steps of: forming a separation layer over a substrate; forming a semiconductor integrated circuit over the separation layer; attaching a first layer to the semiconductor integrated circuit and attaching a second layer to the first layer, the first layer being interposed between the semiconductor integrated circuit and the second layer; separating the semiconductor integrated circuit from the substrate; attaching a third layer to the semiconductor integrated circuit separated from the substrate and attaching a fourth layer to the third layer, the third layer being interposed between the semiconductor integrated circuit and the fourth layer; and forming a conductive layer so that the conductive layer and the semiconductor integrated circuit are electrically insulated from each other, wherein the first layer includes an organic resin and a fibrous body, wherein the third layer includes an organic resin and a fibrous body, wherein the second layer has a lower modulus of elasticity and higher breaking strength than the first layer, wherein the fourth layer has a lower modulus of elasticity and higher breaking strength than the third layer, and wherein the third layer and the fourth layer are between the conductive layer and the semiconductor integrated circuit.
