Title: Manufacture of semiconductor device
Inventor: MAEDA SHIGENOBU
IPC: H01L21/336
Filed: 1992-12-21
Abstract: PURPOSE:To obtain a TFT with a small variation in characteristic, a small step and a good mass productivity. CONSTITUTION:A gate electrode 8 is selectively formed on an oxide film 2 and further a gate insulating film 4 is formed on the entire surface. An amorphous silicon is deposited to a thickness of 1000Angstrom  or more on this insulating film 4 and a solid phase growth of a polysilicon is performed. Though this polysilicon has a small variation in crystal grain diameter, a step in the proximity of the end of the gate electrode 8 increases if the polysilicon is used in an active layer without treatment. In order to avoid this step, the surface is oxidized and a silicon oxide film 2a is formed. Since a polysilicon 3a is left, the silicon oxide film 2a is then removed and thereby the thin polysilicon 3a can be obtained. Thus, the variation in crystal grain diameter is reduced and the thin polysilicon is formed.
