Abstract:
1. A method of forming a photoresist pattern comprising: a step of forming a photoresist film by applying a photoresist to a substrate; a step of forming an upper layer film on the photoresist film; and a step of forming a resist pattern by irradiating the photoresist film and the upper layer film with radiation via water through a mask having a specific pattern, and developing the resist pattern, wherein the step of forming an upper layer film is carried out using an supper layer film forming composition comprising: wherein R wherein the resin (A) has at least one repeating unit selected from repeating units shown by the following formulas (I-1), (I-2), and (I-3), wherein R wherein an amount of the compound (B) is 3 parts by mass or less for 100 parts by mass of the resin (A).
