Patent ID: 7459353

Claim:
A method of manufacturing a semiconductor device comprising: forming a first insulation layer on a first single crystalline structure including a single crystalline material, the first insulation layer having an opening that exposes the first single crystalline structure; forming a first seed layer including the single crystalline material in the opening; forming a first amorphous thin film on the first insulation layer and the first seed layer; changing a phase of a first region of the first amorphous thin film, the first region of the first amorphous thin film being overlapped with the first seed layer; transforming the first region of the first amorphous thin film into a first single crystalline thin film including the single crystalline material, by converting a crystalline structure of the first region of the first amorphous thin film into a single crystalline structure, using the single crystalline material in the first seed layer as a seed during a phase transition of the first region of the first amorphous thin film; changing a phase of a second region of the first amorphous thin film, the second region of the first amorphous thin film being adjacent to the first single crystalline thin film, wherein the first region of the first amorphous thin film has an area substantially larger than that of the second region of the first amorphous thin film; and transforming the second region of the first amorphous thin film into a second single crystalline thin film including the single crystalline material, by converting a crystalline structure of the second region of the first amorphous thin film into a single crystalline structure, using the single crystalline material in the first single crystalline thin film as a seed during a phase transition of the second region of the first amorphous thin film.
