Abstract

PURPOSE:To obtain a resist pattern for use in microscopic fabrication of highly integrated semiconductor parts, by exposing an organic film coated on a substrate to far ultraviolet rays, immersing it in an aromatic amine solution, baking it, and further immersing it in a similar solution. CONSTITUTION:An organic polymer film containing epoxy groups is coated on a substrate, and exposed to far ultraviolet rays to form a pattern, immersed in a solution containing 2-10% aromatic amine at 15-30 deg.C, and baked at 100- 300 deg.C. It is again immersed in a solution containing a >=10% aromatic amine at >=40 deg.C, thus permitting a high-resolution resist pattern formed by far ultraviolet ray irradiation to be applied to dry etching using ion plasma causing small side etching.
