Abstract:
A method of producing a substrate having an alignment mark includes a process of forming a lower layer side metal film on a substrate and forming a lower layer side alignment mark base having a lower layer side alignment mark that is a hole, a process of forming an upper layer side metal film on the substrate and the lower layer side metal film, a process of forming a photoresist film on the upper layer side metal film and forming a lower layer side alignment mark overlapping portion overlapping a part of the lower layer side alignment mark with patterning, an etching process of removing with etching selectively portions of the lower and upper layer side metal films not overlapping the lower layer side alignment mark overlapping portion and forming an upper layer side alignment mark that is the upper layer side metal film, and a photoresist removing process.

Claim (Index 3):
A method of producing a substrate having an alignment mark comprising:\n a lower layer side metal film forming process of forming a lower layer side metal film on a substrate and forming a lower layer side alignment mark; an upper layer side metal film forming process of forming an upper layer side metal film on the substrate and the lower layer side metal film; a photoresist film forming process of forming a photoresist film on the upper layer side metal film and forming a lower layer side alignment mark non-overlapping portion with patterning, the lower layer side alignment mark non-overlapping portion not overlapping the lower layer side alignment mark and having a lower layer side alignment mark overlapping hole overlapping the lower layer side alignment mark; an etching process of removing with etching selectively portions of the lower layer side metal film and the upper layer side metal film not overlapping the lower layer side alignment mark non-overlapping portion that is the photoresist film, and forming an upper layer side alignment mark base that is formed from the upper layer side metal film, the upper layer side alignment mark base including an upper layer side alignment mark that is a hole overlapping the lower layer side alignment mark overlapping hole; and a photoresist removing process of removing the photoresist film.
