Abstract:
A fabrication method of a nanoimprint mold core includes providing a substrate having a photo phase change surface; performing a phase change on the photo phase change surface to form at least one first area and at least one second area; at least partially removing the first area to form a nano pattern; performing an imprinting process using the substrate having the nano pattern; and performing a mold release process so as to obtain the mold core. This achieves the advantages of low cost, high yield, and easy fabrication of the mold core.
Abstract:
A method for fabricating a nanoimprint mold core is disclosed. The method includes providing a substrate; forming on the substrate an amorphous thin film, which is transformed into a crystalline thin film upon receipt of energy, the crystalline thin film having physical and chemical characteristics different from those of the amorphous thin film; applying the energy onto a predetermined region of the amorphous thin film, to transform the amorphous thin film within the predetermined region into the crystalline thin film; etching the illuminated amorphous film, which has crystalline mark on amorphous film, and at least partially removing the area of remained amorphous thin films; performing an imprinting process on the substrate, which has the etched amorphous thin films formed; and performing a molding releasing process on the substrate, so as to obtain the nanoimprint mold core.

An optical film includes: a structured-surface layer and a supporting layer bonded with the structured-surface layer, wherein the structured-surface layer includes a plurality of upper prismatic or structured protrusions formed on an upper portion of the structured-surface layer and having a plurality of lower prismatic protrusions or lower protrusions formed on a bottom portion of the structured-surface layer. The supporting layer is recessed with a plurality of notches to be engaged with the lower protrusions of the structured-surface layer to thereby firmly interlock the structured-surface layer with the supporting layer to increase the film strength and also to increase the brightness of the optical film.
Abstract:
A microfabrication process comprises the swelling of at least a hydrophilic polymer in order for shrinking each cavity size of a micromachined microstructure pattern from three-dimensional orientations, whereby upon filling or deposition of metal into each cavity of the pattern when performing an electroforming step, a supermini microstructure with slim, fine, thin and small size can be obtained as geometrically miniaturized from three-dimensional orientations.
