Title: Separating method of organic material
Inventor: WAKANA HIDEYUKI
IPC: H01L21/306
Filed: 1983-10-04
Abstract: PURPOSE:To completely remove an organic material from a substrate by emitting ultraviolet rays to H2O2 water contacted with an organic material film on the substrate, injecting the H2O2 water emitted with the ultraviolet rays to the film, or alternately contacting heated sulfuric acid or H2O2 water with the film after emitting the ultraviolet rays. CONSTITUTION:Ultraviolet rays 3A is emitted with sufficient illumination to generate radical O and O2, an organic material film is oxidized, and isolated from a substrate 1A. When the concentration of H2O2 water 2 and pH are selected, strong oxidation occurs. The H2O2 water does not corrode the metal, but only the film 1 is removed. Since dangerous strong acid is not used, it is safety, and the treating time can be shortened. After ultraviolet rays 3A are emitted, the sulfuric acid may be contacted with the film 2. If the heated sulfuric acid and the H2O2 are alternately contacted with the film 2, the effect can be further obtained.
