Abstract

PURPOSE:To accurately form a fine pattern by laying a polyimide layer on a substrate, masking the layer with a resist, and pattering the layer with gaseous plasma contg. a fluorocarbon compound. CONSTITUTION:Polyimide layer 2 is laid on Al or Si substrate 1, and on layer 2 resist layer 3 is formed with a commercially available resist in a thickness corresponding to about 1/3 of the thickness of layer 2. Using layer 3 as a mask disclosed part (a) of layer 2 is etched with plasma of a gaseous fluorocarbon compound such as CF4 contg. O2. Since the etching speed of polyimede layer 2 is 3-4 times as high as that of resist layer 3, layer 2 is etched selectively. Layer 3 is then removed to accurately obtain a polyimide pattern with disclosed substrate 1. Using this polyimide film an insulating layer, etc. for a semiconductor devices, etc. are obtd. with high resolution.
