本実施の形態では、本発明の一態様に係る構成の一例について説明する。
本実施の形態では、本発明の一態様に係る構成の具体例について説明する。ここでは特に、半導体装置10が、検出した生体情報が正常値であるか異常値であるかを判別する健康管理システムとしての機能を有する構成について説明する。
本実施の形態では、回路50に用いることができるトランジスタの構成について説明する。
本実施の形態では、記憶回路または論理回路に用いることができるトランジスタの構成について説明する。
図15に、トランジスタ620、630の構成の一例を示す。なお、図15では、OSトランジスタであるトランジスタ630が、チャネル形成領域に酸化物半導体以外の材料を有するトランジスタであるトランジスタ620上に形成されている場合を例示している。
次いで、OSトランジスタの構成例について説明する。
以下では、酸化物半導体膜の構造について説明する。なお、以下の説明において、「平行」とは、二つの直線が−10°以上10°以下の角度で配置されている状態をいう。従って、−5°以上5°以下の場合も含まれる。また、「垂直」とは、二つの直線が80°以上100°以下の角度で配置されている状態をいう。従って、85°以上95°以下の場合も含まれる。また、本明細書において、結晶が三方晶または菱面体晶である場合、六方晶系として表す。
まずは、CAAC−OS膜について説明する。
次に、微結晶酸化物半導体膜について説明する。
次に、非晶質酸化物半導体膜について説明する。
本実施の形態では、図15とは異なる構造を有する半導体装置の構造の一例について説明する。
他の実施の形態で開示された、導電膜、半導体膜、絶縁膜など様々な膜はスパッタ法やプラズマCVD法により形成することができるが、他の方法、例えば、熱CVD法により形成してもよい。熱CVD法の例としてMOCVD(Metal Organic Chemical Vapor Deposition)法やALD(Atomic Layer Deposition)法を使っても良い。
本実施の形態では、本発明の一態様に係る半導体装置の使用形態の例について説明する。
