Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a first shape of semiconductor region on an insulating surface, the first shape of semiconductor region having on one side thereof a plurality of sharp convex top-end portions; scanning the first shape of semiconductor region from the plurality of convex top-end portions to another end portion opposing thereto with a continuous wave laser beam; and etching the first shape of semiconductor region to form a second shape of semiconductor region in which a channel forming region and a source and drain region are formed; wherein, in the second shape of semiconductor region, a plurality of rectangular semiconductor regions are disposed so that a channel forming region is formed in respective crystal regions extending from the plurality of convex top-end portions; and wherein the etching process is performed so that a portion of the first shape of semiconductor region adjacent to the channel forming region is removed.
