  • Patent number: 8921135
    Abstract: A method for manufacturing a device having a concavo-convex structure includes forming an organic resist film on an n-type semiconductor layer in which a fine concavo-convex structure is to be formed; forming a silicon-containing resist film on the organic resist film; patterning the silicon-containing resist film by nanoimprint; oxidizing the silicon-containing resist film with oxygen-containing plasma to form a silicon oxide film; dry-etching the organic resist film by using the silicon oxide film as an etching mask; dry-etching the n-type semiconductor layer by using the silicon oxide film and the organic resist film as an etching masks; and removing the silicon oxide film and the organic resist film.

  • Publication number: 20130323347
    Abstract: A demolding device (7) transfers a fine transfer pattern formed on a sheet-shaped mold to a molded product, and then detaches the sheet-shaped mold, which adheres to the molded product, from the molded product. The demolding device (7) includes a molded product holder (19) placed in a location away from a transfer device (5) and configured to hold a molded product (W) out of a mold (MA) and the molded product (W) adhering to each other, and a detaching roller unit (23) on which the mold (MA) adhering to the molded product (W) held by the molded product holder (19) is wound, and which is configured to move relative to the molded product holder (19) and thereby to detach the mold (MA) from the molded product (W).
