Abstract:
A method of manufacturing a semiconductor device, said method comprising the steps of:forming an amorphous semiconductor film on an insulating surface; providing a crystallizing accelerating material with the amorphous semiconductor film using a spin coating method; heating the amorphous semiconductor film to form a crystalline semiconductor film; applying a laser light to the crystalline semiconductor film; and forming a plurality of thin film transistors, each of said thin film transistors comprising the crystalline semiconductor film having a source region, a drain region, a channel region and a pair of lightly doped impurity regions, wherein the crystalline semiconductor film comprises (111) plane, (220) plane and (311) plane, wherein a ratio of a reflection intensity of the (111) plane to sum of reflection intensities of the (111) plane, (220) plane and (311) plane amounts to larger than 90%, and wherein the reflection intensities of the (111) plane, (220) plane and (311) plane are measured by x-ray diffraction.
