Abstract
【解決手段】材料12の層を基板10上にプリパターニングする工程と、膜形成物質溶液16をプリパターニングされた基板上にスピンコートする工程と、膜形成物質の膜16を乾燥させる工程と、プリパターニングされた材料の側面にのみ乾燥された膜が残るように、当該膜をエッチングする工程と、プリパターニングされた物質の輪郭に対応した形状を有する隆起部20が基板上に残るように、プリパターニングされた材料を取り除く工程と、を有することを特徴とする。 パターニングされた基板上に、金属層を蒸着して隆起部を取り除く。そして、半導体、絶縁体及び導電体、ソース及びドレイン電極の組にそれぞれ設けられ後の工程で形成されるゲート電極の領域に選択的に蒸着することによって、薄膜トランジスタのアレイを形成する。
