Patent ID: RE42097

Claim:
A method of manufacturing a semiconductor device comprising: forming an oxide layer on a single crystal semiconductor substrate; adding hydrogen ions into the single crystal semiconductor substrate through the oxide layer to form a hydrogen-containing layer; bonding the single crystal semiconductor substrate and a glass substrate with at least the oxide layer located between the single crystal semiconductor substrate and the glass substrate wherein bonding surfaces between the single crystal semiconductor substrate and the glass substrate are hydrophilic; separating the single crystal semiconductor substrate by a first heat treatment along the hydrogen-containing layer so that a single crystal semiconductor layer remains on the oxide layer over the glass substrate; patterning the single crystal semiconductor layer to form an island-like semiconductor layer wherein the single crystalline semiconductor layer subject to the patterning step is 20 to 100 nm thick; forming a gate insulating film on the island-like semiconductor layer; forming a gate electrode over the island-like semiconductor layer with the gate insulating film interposed therebetween; forming an interlayer insulating film over the island-like semiconductor layer and the gate electrode.
