Abstract:
A method of manufacturing a semiconductor device, the method comprising:forming an amorphous semiconductor film by plasma CVD through intermittent electric discharge, the amorphous semiconductor film containing germanium with a composition ratio to silicon greater than or equal to 0.1 atomic percent and less than or equal to 10 atomic percent, and providing the amorphous semiconductor film with an element for promoting crystallization of the amorphous semiconductor film, and then subjecting the film to heat treatment to form a semiconductor film having a polycrystal structure, wherein:a channel formation region is formed from the semiconductor film having a polycrystal structure, and the {101} planes in the semiconductor film having a polycrystal structure reach 30% or more of all the lattice planes detected by Electron backscatter diffraction.
