Patent ID: 8900953

Claim:
A method of manufacturing a semiconductor device, comprising: a first step of producing an underlying layer comprising one of a semiconductor layer formed on a substrate including one of a hetero-substrate of a material different from semiconductor and a semiconductor substrate, an insulating layer formed on said substrate, and a semiconductor layer/an insulating layer formed on said substrate; a second step of producing a crystalline semiconductor layer by discharging a droplet of a constituent element of the semiconductor to a desired position on said substrate at a desired initial speed; and a third step of manufacturing a semiconductor device using at least one of said produced crystalline semiconductor layer and said underlying layer, wherein the first step comprises: a first sub step of producing an amorphous layer on said substrate; and a second sub step of producing an insulating layer on said amorphous layer, wherein in said second step, said crystalline semiconductor layer is produced by discharging said droplet on said insulating layer, thereby crystallizing said amorphous layer; and wherein the second step includes discharging the droplet by moving up and down a piston contacting with a melt comprising the constituent element of the semiconductor.
