Patent ID: 7754416

Claim:
A process for producing a resist pattern comprising: laminating (a) a support having an upper surface comprising copper, (b) an inorganic substance layer consisting of an inorganic substance supplied from an inorganic substance source on the upper surface of said (a) support, and (c) a photoresist layer consisting of a chemically amplified type positive photoresist composition on the upper surface of said (b) inorganic substance layer, to obtain a photoresist laminate; selectively irradiating active light or radioactive rays to said photoresist laminate; and developing both said (b) inorganic substance layer and said (c) photoresist layer, thereby removing together both the exposed part of the (c) photoresist layer and the (b) inorganic substance layer which exists under the exposed part of the (c) photoresist layer so as to form a resist pattern, wherein the inorganic substance is at least one selected from the group consisting of Al, Zn, Mo, Sn, Pb, and ITO.
