Abstract:
A method for fabricating a resist pattern having a T-shaped longitudinal cross section which is constructed of a main body having a substantially rectangular longitudinal cross section and a supplemental body to support the main body on a given base material and having a substantially rectangular longitudinal cross section narrowed as compared with the longitudinal cross section of the main body, comprising the steps of:forming a polymethylglutarimide layer on a given base material, washing the surface of the polymethylglutarimide layer with an organic solvent, forming a photoresist layer on the polymethylglutarimide layer, exposing and developing the photoresist layer via a given mask, and partially removing the remaining polymethylglutarinide layer with an alkaline water solution, to form the resist pattern.
