Title: Cleaning method for semiconductor substrate
Inventor: KITANI MASARU
IPC: C23C16/02
Filed: 1988-10-04
Abstract: PURPOSE:To prevent yield lowering due to particles by carrying out cleaning treatment for a semiconductor substrate using mixed solution of sulfuric acid and hydrogen peroxide to improve the cleaning effect to make a gate oxide film thinner. CONSTITUTION:Sulfuric acid and hydrogen peroxide are mixed at the rate of 4:1 and heated to 100 deg.C to clean a semiconductor substrate. When this mixed solution is used, the etching of silicon at the substrate surface is promoted to an extent not to generate surface roughness so that the cleaning efficiency is improved. Thus, the yield lowering due to particles caused by thinning of a gate oxide film accompanying refinement of a semiconductor device can be prevented. This is because the particle removing ratio is improved by the promotion of said etching.
