Patent ID: 8324055

Claim:
A method of manufacturing a semiconductor device, comprising: implanting hydrogen ions into a donor substrate through a first surface thereof to form an ion implantation region, the donor substrate comprising a single crystalline semiconductor; forming a conductive layer comprising a metal on the first surface of the donor substrate; forming an insulation layer comprising silicon oxide on the conductive layer; bonding the insulation layer to a support substrate; cutting the donor substrate at the ion implantation region to form a single crystalline semiconductor layer; patterning the single crystalline semiconductor layer in a first region to form a first active structure comprising a first lower pattern and a first upper pattern, the first lower pattern extending in a first direction, and the first upper pattern protruding from the first lower pattern; etching the conductive layer using the first active structure as an etching mask to form a buried wiring between the first active structure and the insulation layer, the buried wiring extending in the first direction; sequentially forming a first gate insulation layer and a first gate electrode on a sidewall of the first upper pattern; forming a first impurity region at the first lower pattern, the first impurity region being electrically connected to the buried wiring; and forming a second impurity region at the first upper pattern, the second impurity region being formed above the first gate electrode.
