Description
本実施の形態では、本発明の一態様である半導体装置及びその作製方法について図面を参照して説明する。
本実施の形態に示すトランジスタ50において、必要に応じて、基板11及びゲート電極15の間に下地絶縁膜を設けてもよい。下地絶縁膜の材料としては、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、下地絶縁膜の材料として、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11から不純物、代表的にはアルカリ金属、水、水素等の多層膜20への拡散を抑制することができる。
本実施の形態に示すトランジスタ50に設けられる酸化物半導体膜18において、不純物濃度が低く、欠陥準位密度の低い酸化物半導体膜を用いることで、さらに優れた電気特性を有するトランジスタを作製することができ好ましい。ここでは、不純物濃度が低く、欠陥準位密度の低い(酸素欠損の少ない)ことを高純度真性または実質的に高純度真性とよぶ。高純度真性または実質的に高純度真性である酸化物半導体は、キャリア発生源が少ないため、キャリア密度を低くすることができる場合がある。従って、当該酸化物半導体をチャネル領域に用いたトランジスタは、しきい値電圧がマイナスとなる電気特性(ノーマリーオンともいう。)になることが少ない。また、高純度真性または実質的に高純度真性である酸化物半導体は、欠陥準位密度が低いため、トラップ準位密度も低くなる。従って、当該酸化物半導体をチャネル領域に用いたトランジスタは、電気特性の変動が小さく、信頼性の高いトランジスタとなる。なお、酸化物半導体のトラップ準位に捕獲された電荷は、消失するまでに要する時間が長く、あたかも固定電荷のように振る舞うことがある。そのため、トラップ準位密度の高い酸化物半導体をチャネル領域に用いたトランジスタは、電気特性が不安定となる場合がある。不純物としては、水素、窒素、アルカリ金属、又はアルカリ土類金属等がある。
本実施の形態に示すトランジスタ50に設けられる一対の電極21、22として、タングステン、チタン、アルミニウム、銅、モリブデン、クロム、またはタンタル単体若しくは合金等の酸素と結合しやすい導電材料を用いることが好ましい。この結果、多層膜20に含まれる酸素と一対の電極21、22に含まれる導電材料とが結合し、多層膜20において、酸素欠損領域が形成される。また、多層膜20に一対の電極21、22を形成する導電材料の構成元素の一部が混入する場合もある。これらの結果、多層膜20において、一対の電極21,22と接する領域近傍に、低抵抗領域が形成される。図4は、図1(B)のトランジスタ50の多層膜20の拡大断面図である。図4(A)に示すように、In若しくはGaを含む酸化物膜19において、低抵抗領域28a、29aの大部分が形成される場合がある。または、図4(B)に示すように、酸化物半導体膜18及びIn若しくはGaを含む酸化物膜19において、低抵抗領域28b、29bが形成される場合がある。または、図4(C)に示すように、酸化物半導体膜18及びIn若しくはGaを含む酸化物膜19において、ゲート絶縁膜17に接するように低抵抗領域28c、29cが形成される場合がある。当該低抵抗領域28a〜28c、29a〜29cは、導電性が高いため、多層膜20と一対の電極21、22との接触抵抗を低減することが可能であり、トランジスタのオン電流を増大させることが可能である。
本実施の形態に示すトランジスタ50の作製方法において、一対の電極21、22を形成した後、エッチング残渣を除去するため、洗浄処理をしてもよい。この洗浄処理を行うことで、一対の電極21、22の間に流れるリーク電流の発生を抑制することができる。当該洗浄処理は、TMAH(Tetramethylammonium Hydroxide)溶液などのアルカリ性の溶液、希フッ酸、シュウ酸、リン酸などの酸性の溶液を用いて行うことができる。
本実施の形態に示すトランジスタ50の作製方法において、一対の電極21、22を形成した後、多層膜20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18及びIn若しくはGaを含む酸化物膜19に酸素を供給してもよい。酸素雰囲気としては、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11側にバイアスを印加しない状態で発生したプラズマに多層膜20を曝すことが好ましい。この結果、多層膜20にダメージを与えず、且つ酸素を供給することが可能であり、多層膜20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多層膜20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。
本実施の形態では、実施の形態1と比較して、酸化物半導体膜の欠陥量をさらに低減することが可能なトランジスタを有する半導体装置について図面を参照して説明する。本実施の形態で説明するトランジスタは、実施の形態1と比較して、ゲート絶縁膜及び酸化物半導体膜の間に、In若しくはGaを含む酸化物膜を有する点が異なる。
本実施の形態に示す図5(A)乃至図5(C)に示す多層膜34の代わりに、図5(D)及び図5(E)に示すように、In若しくはGaを含む酸化物膜31、酸化物半導体膜32、In若しくはGaを含む酸化物膜33、及びIn若しくはGaを含む酸化物膜35を有する多層膜34aを用いることができる。なお、図5(D)は、図5(B)に示す多層膜34の近傍の拡大図に相当し、図5(E)は、図5(C)に示す多層膜34近傍の拡大図に相当する。
本実施の形態に示すトランジスタ60において、多層膜34及び一対の電極21、22の積層構造は適宜変更することができる。例えば、変形例として図7に示すようなトランジスタ65とすることができる。

本実施の形態に示すトランジスタ60において、多層膜34及び一対の電極21、22の積層構造は適宜変更することができる。例えば、変形例として図11に示すようなトランジスタ67とすることができる。

本実施の形態では、表示装置の消費電力を低減するための駆動方法について説明する。本実施の形態の駆動方法により、画素に酸化物半導体トランジスタを適用した表示装置の更なる低消費電力化を図ることができる。以下、図33及び図34を用いて、表示装置の一例である液晶表示装置の低消費電力化について説明する。
