Abstract:
A fine pattern forming method, comprising the steps of:coating a resist, which contains a material generating acid by heating or light irradiation, on a substrate; forming a resist pattern by exposing the resist through a pattern, developing the resist, and washing a developing solution out with a washing solution; coating a fine pattern forming material containing a material, which is cross-linked by existence of acid, on the substrate in a state where the washing solution is adhered to the substrate; generating acid in the resist pattern by heating or light irradiation; covering the resist pattern with a cross-linked layer generated on an interface between the resist pattern and the fine pattern forming material; developing a not-cross-linked layer of the fine pattern forming material by a developing solution for the fine pattern forming material; and washing the developing solution out with a washing solution.
