Abstract:
1. A method of forming resist patterns which comprises the steps of (a) applying and forming a chemically amplified photoresist film on a substrate, (b) applying a treating agent with a pH value of 1.3 to 4.5 onto said chemically amplified photoresist film, (c) baking said chemically amplified photoresist film after at least one of the steps of applying and forming said chemically amplified photoresist film and applying said treating agent, (d) selectively exposing said chemically amplified photoresist film, (e) post exposure-baking said chemically amplified photoresist film, and (f) developing said chemically amplified photoresist film, wherein the contact angle of a non-exposed portion of said chemically amplified photoresist film to a developing solution after washing with water to remove the treating agent on the photoresist and spin-drying before development is made lower by 10° to 110° than that in the case where said treating agent is not applied, wherein said treating agent comprises at least the following components (A), (B), (C), (D) and (E); (A) perfluoroalkylsulfonic acid represented by the general formula: wherein m is an integer of 4 to 10, (B) organic amine, (C) water-soluble polymer, (D) Perfluoroalkyl sulfonamide represented by the general formula: Wherein n is an integer of 1 to 8, and (E) waters.
