Title: Pattern forming method
Inventor: OGAWA KOICHI
IPC: H01L21/306
Filed: 1990-10-16
Abstract: PURPOSE:To precisely form a pattern part by a method wherein, when the pattern part is formed, etching is interrupted in the state where etching residue is left, and then the whole surface layer part is turned into material to be unified with a base layer by heat-treating the whole part. CONSTITUTION:A pattern layer 3 of polysilicon is stuck on a base layer 2 of silicon oxide. By using a patterned photo resist as a mask, the pattern layer 3 is etched and a pattern part 5 is formed. This etching is interrupted in the state where etching residue 6 is left. After that, the whole surface layer part 7 containing the etching residue 6 is turned into silicon oxide to be unified with the base layer 2 by heat-treating the whole part, and the surface layer part 7 is eliminated by wet etching. Thereby excessive side etching can be prevented from progressing, and the pattern part 5 can be formed with superior precision.
