ル用ワークスタンパを得ることが出来る。First, mask writing is performed on the glass master based on desired data. Next, by subjecting the glass master to Ni sputtering and electroforming, a Ni stamper (mask) is formed.
cause Next, electroforming is performed again using the Ni stamper (mask) as a mold to produce a Ni stamper (mother). Using the Ni stamper (mother) produced in this manner, a resin film sol-gel work stamper can be obtained by injection molding or 2P molding.

出来る。Next, an alcohol solution (sol-gel solution) containing metal alcoholate, polyethylene glycol, and hydrochloric acid is applied onto the glass substrate by a spin coating method to form a sol-gel layer. Press the work stamper from earlier onto this sol-gel surface to transfer the fine pattern. After primary firing is performed while the substrates are overlapped, the finely patterned glass substrate released from the work stamper is further subjected to secondary firing. Through such a process, a glass substrate for an optical disc can be obtained.
（発明が解決しようとする課題）
先述したように、ゾルゲル用ワークスタンパを作製する

、正確なパターン転写が出来ない。(Problems to be Solved by the Invention) As mentioned above, manufacturing a sol-gel work stamper currently requires a considerable number of processes. This is a direct Ni stamper (
master) is unavailable. That is, if primary baking is performed with the sol-gel layer and the Ni stamper in close contact with each other, a portion of the sol-gel layer will adhere to the surface of the Ni stamper when the mold is released, making it impossible to accurately transfer the pattern.
このため上述したような長いプロセスを採り入れている
が、特に微細なパターンを比較的大面積に渡って何度も
転写するので、歩留り、コストの面で問題となる。For this reason, a long process as described above is employed, but this poses problems in terms of yield and cost, as particularly fine patterns are transferred over a relatively large area many times.
本発明は、上述した問題を解決するゾルゲル用ワークス
