Description
本実施の形態では、本発明の一態様である半導体装置について図面を用いて説明する。
本実施の形態では、実施の形態1に示すトランジスタ217および容量素子219に適用可能な変形例について、説明する。
図11(A)は、実施の形態1に示すトランジスタ217の酸化物半導体膜408aと導電膜410aおよび導電膜410bとのコンタクトの方法が図5と異なる。本変形例は、ボトムコンタクト型のトランジスタ257である。
実施の形態1に示すトランジスタ217において、必要に応じて、基板402およびゲート電極404の間に下地絶縁膜を設けることができる。下地絶縁膜としては、酸化シリコン、酸化窒化シリコン、窒化シリコン、窒化酸化シリコン、酸化ガリウム、酸化ハフニウム、酸化イットリウム、酸化アルミニウム、酸化窒化アルミニウム等がある。なお、下地絶縁膜として、窒化シリコン、酸化ガリウム、酸化ハフニウム、酸化イットリウム、酸化アルミニウム等を用いることで、基板402から不純物、代表的にはアルカリ金属、水、水素等の酸化物半導体膜408aへの拡散を抑制することができる。
実施の形態1に示すトランジスタ217において、必要に応じて、ゲート絶縁膜として機能する絶縁膜の積層構造を変形することができる。
実施の形態1に示すトランジスタ217において、導電膜410a、導電膜410bに用いることが可能な材料について、説明する。
実施の形態1に示すトランジスタ217の作製方法において、導電膜410a、導電膜410bを形成した後、酸化物半導体膜408aを酸素雰囲気で発生させたプラズマに曝し、酸化物半導体膜408aに酸素を供給することができる。酸化雰囲気としては、酸素、オゾン、一酸化二窒素、二酸化窒素等の雰囲気がある。さらに、当該プラズマ処理において、基板402側にバイアスを印加しない状態で発生したプラズマに酸化物半導体膜408aを曝すことが好ましい。この結果、酸化物半導体膜408aにダメージを与えず、かつ酸素を供給することが可能であり、酸化物半導体膜408aに含まれる酸素欠損量を低減することができる。また、エッチング処理により酸化物半導体膜408aの表面に残存する不純物、例えば、フッ素、塩素等のハロゲン等を除去することができる。
実施の形態1に示すトランジスタ217において、必要に応じて、酸化物半導体膜を積層構造とすることができる。
変形例6において、酸化物半導体膜を含む多層膜の構造を適宜変形することができる。
実施の形態1に示すトランジスタ217において、必要に応じて、酸化物半導体膜を介して対向する複数のゲート電極を設けることができる。
本発明の一態様である半導体装置は、被検知体の近接または接触を検知可能なセンサ(たとえば、静電容量方式、抵抗膜方式、表面弾性方式、赤外線方式、光学方式などのタッチセンサ)や医療用の放射線画像を取得することが可能な放射線画像検出装置に適用することができる。また、本発明の一態様である半導体装置はさまざまな電子機器(遊技機も含む)に適用することができる。電子機器としては、テレビジョン装置(テレビ、またはテレビジョン受信機ともいう)、コンピュータ用などのモニタ、デジタルカメラ、デジタルビデオカメラ、デジタルフォトフレーム、携帯電話機、携帯型ゲーム機、携帯情報端末、音響再生装置、遊技機(パチンコ機、スロットマシン等)、ゲーム筐体が挙げられる。これらの電子機器の一例を図19に示す。
