Abstract
(EN)

PROBLEM TO BE SOLVED: To improve field-effect mobility and reliability, in a transistor having an oxide semiconductor film.

SOLUTION: A semiconductor device having an oxide semiconductor film comprises: a first insulating film; an oxide semiconductor film on the first insulating film; second and third insulating films on the oxide semiconductor film; and a gate electrode on the second insulating film. Especially, the second insulating film includes a silicon oxynitride film, and has excess oxygen by oxygen plasma processing, and thereby, can supply oxygen to the oxide semiconductor film with efficiency.

【課題】酸化物半導体膜を有するトランジスタにおいて、電界効果移動度を向上させると共に信頼性を向上させる。
【解決手段】酸化物半導体膜を有する半導体装置であって、半導体装置は、第1の絶縁膜と、第1の絶縁膜上の酸化物半導体膜と、酸化物半導体膜上の第2の絶縁膜及び第3の絶縁膜と、第2の絶縁膜上のゲート電極と、を有する。特に第2の絶縁膜は酸化窒化シリコン膜を含み、酸素プラズマ処理によって過剰酸素を有することで、酸化物半導体膜への酸素供給を効率良く行うことができる。
