Title: Production of stamper
Inventor: NISHIKAWA HISAO
IPC: B29C45/26
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain a having surface smoothness of a high degree by subjecting a silicon substrate 1 formed with rugged patterns to a heat treatment of a prescribed temp., thereby smoothing its surface. SOLUTION: The surface roughness of the rugged patterns is increased by unequal etching and the formation of a natural oxidized film 11 on the silicon substrate 1 surface, etc., during an etching stage of forming the desired rugged patterns on the silicon substrate 1 surface. Namely, silicon terminals are bonded to OH groups on the silicon substrate 1 surface formed with the oxidized film 11. When the substrate is heat treated for 5 to 60 minutes at 600 to 900 deg.C in a hydrogen atmosphere, the OH groups are substituted with the hydrogen. The hydrogen is smaller in atomic size than the OH groups and is easily dulled by heat and, therefore, the surface roughness may be decreased. Then, the surface of the rugged patterns of the silicon substrate 1 may be smoothed. As a result, the high-reliability stamper having the improved surface smoothness is obtd.
