Description
本発明の実施の形態1に係る半導体装置として液晶表示装置について説明する。図1は、液晶表示装置のTFTアレイ基板の構成を示すブロック図である。まず、画像を表示するための画素部21は、画素薄膜トランジスタ22、液晶(画素容量)23、蓄積容量24、コモン電極(コモン線)25、データ線26、アドレス線27、Cs(Common Source)線28および画素電極29から構成されている。
そのレジストパターン62a,62bをマスクとして、たとえばドーズ量7×1012atom/cm2、加速エネルギ80KeVにて不純物領域4aaにリンを注入することにより、領域R1,R2にはそれぞれ不純物領域4ab,4acが形成される。この注入量がGOLD領域における注入量(1×1018atom/cm3)になる。その後、アッシングと薬液処理を施すことで、レジストパターン62a,62bが除去される。
ここでは、GOLD領域に加えてLDD領域を含む薄膜トランジスタを有する液晶表示装置のTFTアレイ基板を例に挙げる。
