ガラス基板101上にスパッタリング法によって、Ti(チタン)、Al(アルミニウム)、および、Tiを順次成膜する。続いて、フォトリソグラフィ法とエッチングを用いてゲート層をパターニングし、ゲート線23、TFT21のゲート電極111、第1共通幹配線16などを形成する。ここで、フォトリソグラフィ法とエッチングを用いたパターニングとは、以下の処理をいう。まず、基板にフォトレジストを塗布する。次に、所望のパターンを有するフォトマスクを被せて基板を露光することにより、基板上にフォトマスクと同じパターンにフォトレジストを残す。次に、残したフォトレジストをマスクとして基板をエッチングすることにより、基板の表面にパターンを形成する。最後に、フォトレジストを剥離する。
図5Aに示す基板にCVD(Chemical Vapor Deposition )法によって、ゲート絶縁膜となるSiNx膜121と、アモルファスSi膜122と、n+アモルファスSi膜123とを連続して成膜する。第2工程では、半導体層のパターニングを行わない。半導体層のパターニングは、ソース層のパターニングと共に第3工程で行われる。
図5Bに示す基板にスパッタリング法によって、MoNb(モリブデンニオブ)膜131を成膜する。続いて、フォトリソグラフィ法とエッチングを用いてソース層と半導体層をパターニングし、データ線24の主導体部133、TFT21の導体部134、第2共通幹配線17の主導体部135などを形成する。TFT21の導体部134は、TFT21のソース電極、ドレイン電極、および、チャネル領域の位置に形成される。第3工程では、主導体部133、135、および、導体部134などの位置にフォトレジスト132を残すフォトマスクが使用される。このため露光後には、主導体部133、135、および、導体部134などの位置にフォトレジスト132が残る(図5C)。フォトレジスト132をマスクとして、まず第3工程で成膜したMoNb膜131をエッチングし、次に第2工程で成膜したn+アモルファスSi膜123とアモルファスSi膜122とを連続してエッチングする(図5D)。これにより、アモルファスSi膜122とn+アモルファスSi膜123は、ソース層とほぼ同じ形状にパターニングされる。最後にフォトレジスト132を剥離することにより、図5Eに示す基板が得られる。図5Eに示す基板では、エッチングされずに残ったMoNb膜131が、データ線24の主導体部133、TFT21の導体部134、および、第2共通幹配線17の主導体部135などになる。図5Eに示す基板では、データ線24の主導体部133、TFT21の導体部134、および、第2共通幹配線17の主導体部135の下層には、アモルファスSi膜122とn+アモルファスSi膜123が存在する。
図5Eに示す基板にスパッタリング法によって、画素電極22となるIZO膜141を成膜する。続いて、フォトリソグラフィ法とエッチングを用いて画素電極層をパターニングする。第4工程では、画素電極22の位置とソース層パターンの位置(ただし、TFT21のチャネル領域の位置を除く)にフォトレジスト142を残すフォトマスクが使用される。このため露光後には、画素電極22の位置、および、ソース層パターンの位置からTFT21のチャネル領域の位置を除いた位置にフォトレジスト142が残る(図5F)。フォトレジスト142をマスクとして、まずウェットエッチングによってIZO膜141とTFT21のチャネル領域の位置に存在する導体部134とをエッチングし、続いてドライエッチングによってTFT21のチャネル領域の位置に存在するn+アモルファスSi膜123をエッチングする(図5G、図5H)。図5Gには、導体部134のエッチングが完了した時点の基板が記載されている。図5Hには、n+アモルファスSi膜123のエッチングが完了した時点の基板が記載されている。図5Hに示すように、ドライエッチングによって、TFT21のチャネル領域に存在するアモルファスSi膜122の膜厚は薄くなる。最後にフォトレジスト142を剥離することにより、図5Iに示す基板が得られる。図5Iに示す基板では、TFT21のチャネル領域が形成され、TFT21のソース電極143とドレイン電極144は分離された状態になる。データ線24の主導体部133、TFT21のソース電極143とドレイン電極144、および、第2共通幹配線17の主導体部135の上層には、IZO膜141が残る。
図5Iに示す基板にCVD法によって、保護絶縁膜となる2層のSiNx膜151、152を順次成膜する。下層SiNx膜151の成膜条件と上層SiNx膜152の成膜条件は異なる(詳細は後述)。続いて、フォトリソグラフィ法とエッチングを用いて、第5工程で形成された2層のSiNx膜151、152、および、第2工程で形成されたSiNx膜121をパターニングする。繋ぎ換え回路を形成する位置には、図5J(d)に示すように、2層のSiNx膜151、152とSiNx膜121を貫通するコンタクトホール153、および、2層のSiNx膜151、152を貫通するコンタクトホール154が形成される。
図5Jに示す基板にスパッタリング法によって、共通電極30となるIZO膜を成膜する。続いて、フォトリソグラフィ法とエッチングを用いて共通電極層をパターニングし、共通電極30と繋ぎ換え電極161を形成する。図5K(d)に示すように、繋ぎ換え電極161は、コンタクトホール153の位置で第1共通幹配線16に直接接触し、コンタクトホール154の位置でIZO膜141を介して第2共通幹配線17の主導体部135に電気的に接続される。また、繋ぎ換え電極161は、共通電極30と一体に形成される。したがって、繋ぎ換え電極161を用いて、共通電極30と第1共通幹配線16と第2共通幹配線17とを電気的に接続することができる。
