Description
本発明者は、TFTを製造するに際して、半導体薄膜、例えばポリシリコン薄膜に歪み(ポリシリコン薄膜の面方向の格子定数を増加させる歪み)を加えるための工程を付加することなく、ゲート電極の形成工程のみにより、即ちゲート電極を形成することにより当該ゲート電極の残留応力(面内方向において格子定数を増加させる方向の残留応力)を利用してポリシリコン薄膜に歪みを加えることに想到し、これを実現すべく具体的手法について鋭意検討した。
以下、本発明をポリシリコンTFTの構成及び製造方法に適用した具体的な諸実施形態について、図面を参照しながら詳細に説明する。なお説明の便宜上、ポリシリコンTFTの構成をその製造方法と共に述べる。
図5A〜図5Fは、第1の実施形態によるCMOS型のポリシリコンTFT(以下、単にCMOSTFTと記す)の製造方法を工程順に示す概略断面図である。
先ず、図5Aに示すように、透明絶縁基板、例えばガラス基板1上に膜厚400nm程度のSiO2からなるバッファー層2を介して、プラズマCVD法によりアモルファスシリコン薄膜3を例えば膜厚65nm程度に成膜する。ここで、成膜時に成膜チャンバー内に例えばB2H6 ガスを混入させることにより、アモルファスシリコン薄膜3中にホウ素(B)をドープしている。
本実施形態では、第1の実施形態とほぼ同様のCMOSTFTの構成及び製造方法を開示するが、nチャネルTFTのゲート電極の膜厚をpチャネルTFTのそれよりも薄く形成する点で相違する。図6A〜図6Gは、第2の実施形態によるCMOS型のポリシリコンTFT(以下、単にCMOSTFTと記す)の製造方法を工程順に示す概略断面図である。なお、第1の実施形態と共通する構成部材等については同符号を記す。
ここで、第2の実施形態の変形例について説明する。
図7A,図7Bは、本変形例の主要工程を示す概略断面図である。
先ず、図6A〜図6Eと同様の諸工程を実行する。
本実施形態では、第2の実施形態とほぼ同様のCMOSTFTの構成及び製造方法を開示するが、nチャネルTFTのゲート電極の膜厚をpチャネルTFTのそれよりも薄くするに際して、pチャネルTFTのゲート電極を2層に形成する点で相違する。図8A〜図8Gは、第3の実施形態によるCMOS型のポリシリコンTFT(以下、単にCMOSTFTと記す)の製造方法を工程順に示す概略断面図である。なお、第2の実施形態と共通する構成部材等については同符号を記す。
ここで、第3の実施形態の変形例について説明する。
