Description
設計から液滴吐出を行うまでのフロー図を図4に説明する。所望の半導体装置を作製するに当たり、まず、CADツールを用いてコンピュータで各部位の設計を行う(S401)。一つの層毎に設計図(露光マスクやドーピングマスクなど)を作成する。
ここでは、絶縁表面を有する基板上にスパッタ法で金属膜を成膜した後、レジスト材料をインクジェット装置で吐出し、得られたレジスト材料層をマスクとして金属膜をエッチングし、配線を形成する例を以下に説明する。
本発明は、配線層若しくは電極を形成する導電層や、所定のパターンに形成するためのマスク層など半導体装置、表示装置などを作製するために必要な構成物のうち、少なくとも一つ若しくはそれ以上を、選択的に所望な形状に形成可能な方法により形成して、半導体装置、表示装置を作製することを特徴とするものである。本発明において、構成物(パターンともいう)とは、薄膜トランジスタや表示装置を構成する、配線層、ゲート電極層、ソース電極層、ドレイン電極層などの導電層、半導体層、マスク層、絶縁層などをいい、所定の形状を有して形成される全ての構成要素を含む。選択的に所望なパターンで形成物を形成可能な方法として、特定の目的に調合された組成物の液滴を選択的に吐出(噴出)して所定のパターンに導電層や絶縁層などを形成することが可能な、液滴吐出(噴出)法(その方式によっては、インクジェット法とも呼ばれる。)を用いる。
