Patent ID: 8304832

Claim:
A manufacturing method of a semiconductor device, comprising: forming a damaged region in a single crystal semiconductor substrate by irradiating the single crystal semiconductor substrate with ions; forming a first wiring layer on a surface of the single crystal semiconductor substrate; forming a first insulating layer on the surface of the single crystal semiconductor substrate; forming a second insulating layer over the first wiring layer and the first insulating layer; bonding the second insulating layer and an insulating substrate to each other; separating a single crystal semiconductor layer from the single crystal semiconductor substrate at the damaged region to form a stack of the first wiring layer and the single crystal semiconductor layer over the insulating substrate; exposing a part of the first wiring layer by patterning the single crystal semiconductor layer; forming a gate electrode over the patterned single crystal semiconductor layer with a gate insulating layer interposed therebetween; forming a third insulating layer over the gate electrode; forming an opening in the third insulating layer so as to expose a part of the first wiring layer; and forming a second wiring layer electrically connected to the first wiring layer through the opening, over the third insulating layer.
