Title: Fabrication of thin film transistor
Inventor: EZAKI TAKAYUKI
IPC: H01L21/336
Filed: 1993-07-02
Abstract: PURPOSE:To fabricate a thin film transistor excellent in characteristics by making thin the channel part of an active layer forming a semiconductor film having excellent film quality as the active layer.
