Patent ID: 8765535

Claim:
A method for manufacturing a semiconductor device, comprising the steps of: forming an insulating layer containing at least yttrium oxide over a silicon substrate; applying heat treatment to the insulating layer; forming an embrittlement layer having a porous structure in the silicon substrate by implanting ion containing hydrogen into the silicon substrate; forming a first electrode over the insulating layer; bonding the silicon substrate to a support substrate with the insulating layer interposed therebetween; separating a part of the silicon substrate along the embrittlement layer so that at least the insulating layer and a single crystal silicon layer are formed over the support substrate; adding an impurity element imparting one conductivity type to the single crystal silicon layer to form an impurity region as a second electrode in order to form a storage capacitor portion including the first electrode, the insulating layer, and the impurity region over the support substrate.
