Abstract
To simplify a peeling step in a method for manufacturing a semiconductor device including the peeling step. A first layer having a metal film is formed over a substrate; a second layer having a transistor is formed over the first layer having the metal film; a resin material is applied over the layer having the transistor; the resin material is cured by a heat treatment at a first heat treatment temperature to form a resin layer; the layer having the transistor is peeled from the substrate by a heat treatment at a second heat treatment temperature which is higher than the first heat treatment temperature; and the resin layer is peeled from the layer having the transistor by a heat treatment at a third heat treatment temperature which is higher than the second heat treatment temperature.
