Abstract:
This process for producing a resist pattern is a process for producing a resist pattern including: the step of laminating (a) a support having an upper surface on which copper exists, (b) an inorganic substance layer consisting of an inorganic substance supplied from an inorganic substance source, and (c) a photoresist layer consisting of a chemically amplified type negative photoresist composition, to obtain a photoresist laminate, the step of selectively irradiating active light or radioactive rays to the photoresist laminate, and the step of developing the (c) photoresist layer together with the (b) inorganic substance layer to form a resist pattern.
