SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE |
摘要 |
An object is to provide a highly reliable semiconductor device having stable electric characteristics by using an oxide semiconductor film having stable electric characteristics. Another object is to provide a semiconductor device having higher mobility by using an oxide semiconductor film having high crystallinity. A crystalline oxide semiconductor film is formed over and in contact with an insulating film whose surface roughness is reduced, whereby the oxide semiconductor film can have stable electric characteristics. Accordingly, the highly reliable semiconductor device having stable electric characteristics can be provided. Further, the semiconductor device having higher mobility can be provided. |
