Abstract:
1. A method of manufacturing a semiconductor device, comprising: attaching a first supporting body to a semiconductor substrate with an adhesive layer, a metal wiring layer being formed on the semiconductor substrate; after the step of attaching the first supporting body, forming a penetration hole penetrating the first supporting body from a front surface to a back surface of the first supporting body by removing a part of the first supporting body; subsequently attaching a second supporting body to the first supporting body with an adhesive layer so as to cover the penetration hole, to seal a device element in a cavity formed by covering the penetration hole of the first supporting body by the semiconductor substrate and the second supporting body, and to include the metal wiring layer in the cavity; and wherein the two adhesive layers are each made of an organic material, and the first supporting body is made of an insulating material.
