Title: Etching method of insulation film of semiconductor device
Inventor: FUJIMOTO KOUJI
IPC: H01L21/302
Filed: 1977-10-26
Abstract: PURPOSE: To smooth the serrations of the etched side walls of insulation film simply by adding a simple process.  
     CONSTITUTION: When a photo resist mask 3 is provided on the insulation film 1 of a Si substrate 2 and the film 1 is etched, overhungs 3a are produced. Since the overhungs 3a are likely to be slightly developed owing to turning about of light at the time of exposure, redeveloping causes the end face to retreat (t), thus magnifying the etched hole and exposing the side wall end face 1A of the side. Etching again through the photo resist mask 3 causes the sharp edges to be selectively removed, forming side walls 1B, 1B'. Next, the mask is removed and an Al vapor deposition film is formed. These eliminate disconnection becuase the surface is smooth.
