Abstract:
A semiconductor device comprising:an electrode on an insulating surface; an insulating film covering said electrode; a semiconductor layer having at least a channel-forming region, a source region, and a drain region on said insulating film, said channel-forming region comprising: silicon and germanium; nitrogen and carbon at less than 5Ã—1018/cm3 as detected by SIMS; oxygen at less than 1Ã—1019/cm3 as detected by SIMS; and a plurality of crystal planes as measured by EBSP method in which an electron beam of 20 nm or less in a spot diameter is irradiated to a plurality of different points of said channel-forming region, wherein ratios of said plurality of crystal planes which form an angle equal to or less than 10Â° with a substrate surface is larger or equal to 20% in {101} plane, less than or equal to 3% in {001} plane, and less than or equal to 5% in {111} plane.
