Abstract
【解決手段】実施形態の半導体装置の製造方法では、半導体基板1上方に被加工膜を形成し、前記被加工膜上にネガ型レジスト3を形成する。前記ネガ型レジスト3上に光硬化性レジスト4が形成され、前記光硬化性レジスト4に、凸部の一部に遮光部が設けられた凹凸パターンを有するテンプレート5の主面側が加圧される。前記テンプレート5の裏面から前記テンプレート5に光が照射され、光が照射されていない前記ネガ型レジスト3及び前記光硬化性レジスト4が現像され、前記テンプレート5の凹凸パターンが前記ネガ型レジスト3及び前記光硬化性レジスト4に転写される。前記ネガ型レジスト3及び前記光硬化性レジスト4に転写された凹凸パターンをマスクとして、前記被加工膜がエッチングされる。
