PURPOSE: To form the accurate and different recesses or projecting parts of the stamper by executing etching under conditions under which 1st and 2nd etching layers can be etched but the etching of an intermediate layer is substantially infeasible.
CONSTITUTION: The etching layer 2, the intermediate layer 3, the etching layer 4, and a negative type photoresist film 6 are successively formed on a substrate 1. After the surface of the film 6 is exposed with lasers of different powers, the film is developed to form guide groove parts 11 and bit parts 12 of different height on the surface of the layer 4. The etching of the layer 4 is then executed in a CF4 atmosphere and the layer 3 is exposed in the parts where there are no resist. The etching is then executed in a CC14 atmosphere until the aluminum of the parts exclusive of the guide groove parts 11 and the bit parts 12 does no longer exist. The layer 2 and the layer 4 are in succession etched under the same conditions until the substrate 1 is exposed in the groove parts 11 and the bit parts 12 and the layer 3 is exposed in the groove parts 11. As a result, the stamper having the guide groove parts and bits of different heights is obtd..
