Description
図1(A)〜(C)を用いて、本発明の薄膜トランジスタの構成について説明する。図1(A)に、本発明の薄膜トランジスタの断面図を、一例として示す。図1(A)では、ゲート電極として機能する導電膜101が、ガラス基板などの絶縁表面を有する基板上に形成されており、該導電膜101を覆うようにゲート絶縁膜102が形成されている。そして、ゲート絶縁膜102上には、ゲート絶縁膜102を間に挟んで導電膜101と重なるように、半導体膜103が形成されている。半導体膜103は、少なくともその一部が導電膜101と重なっていていれば良い。
本実施の形態では、本発明の薄膜トランジスタの作製工程を、一例として示す。本実施の形態では、図2(A)に示した薄膜トランジスタの作製方法を例に挙げて説明するが、本実施の形態で示す作製方法は、図1(A)〜(C)、図2(B)、(C)に示した他の形態を有する薄膜トランジスタの作製方法にも、適宜適用させることが可能である。
本実施の形態では、本発明の薄膜トランジスタをスイッチング素子として用いた、液晶表示装置の構成について説明する。
