  • Publication number: 20140151936
    Abstract: A pattern transferring apparatus is disclosed which can prevent damage to a transferred pattern and realize fast mold release regardless of the type of resist. The pattern transferring apparatus transfers a pattern formed on a mold to an object by bringing the mold into contact with the apparatus has a deformer which causes deformation in the mold for releasing the mold from the object. The apparatus transfers a pattern formed on a mold to a photo-curing resin by bringing the mold into contact with the photo-curing resin and applying light thereto to cure the photo-curing resin. The apparatus has an optical system which applies light at an irradiation light intensity to a non-transfer area other than a transfer area where the pattern is to be transferred in the photo-curing resin, the intensity being different from an irradiation light intensity of light applied to the transfer area.

  • Patent number: 7690912
    Abstract: One object of the present invention is to provide a pattern transferring mold which can provide a starting area of mold release easily and certainly and a pattern transferring apparatus with the same. A pattern transferring mold is disclosed which is used in a pattern transferring apparatus that brings the mold into contact with a photo-curing resin on a substrate and cures the photo-curing resin by light irradiation to transfer a pattern formed on the mold onto the photo-curing resin. The mold comprises a bottom face which contacts the photo-curing resin, the bottom face portion including a first area in which the pattern is formed and a second area formed outside the first area. The mold has a mold-releasing shape in the second area, the mold-releasing shape providing a starting area of mold release from the cured photo-curing resin.
