Description
前記フォトレジスト膜を現像することにより、前記表面レジスト層が逆テーパ形状であり、前記下層レジスト層が前記表面レジスト層に対してアンダーカット形状であるレジストパターンに加工する工程と、
前記レジストパターン上に電極、配線材料となる金属膜を形成する工程と、
前記レジストパターンを溶剤で溶解させるとともに前記レジストパターン上の前記金属膜を除去する工程と、を含むことを特徴とする半導体装置の製造方法を提供する。
以下に、本実施の形態におけるレジストパターンの製造方法を図2(a)から(e)を参照しながら説明する。
(1)図1に示したように、確実にレジスト側壁部で金属膜の段切れを生じさせることにより、リフトオフ処理時間は大幅に短縮され、かつ金属パターン20pの外周部にはバリは全く発生しない。
(2)金属パターンの寸法精度については半導体素子を製造する上で求められる精度に合せ、レジスト断面形状を制御することにより必要な寸法精度が得られる。
