  • Patent number: 10153173
    Abstract: The present invention relates to a process for selectively removing a block on one side using a wet etching process in connection with self-assembly block copolymer thin films that have etching-resisting properties different from each other. The present invention can form a vertical nanopore structure having a high aspect ratio, even in the case of a thick film which has a vertically oriented cylinder self-assembly structure and which has one or more periods, by overcoming the limit of the prior art, which cannot implement a vertical pore structure through wet etching.

  • Patent number: 9788434
    Abstract: The present invention relates to a preparation method for a dry film solder resist (DFSR) capable of forming the DFSR having fine unevenness on a surface by a more simplified method, and a film laminate used therein. The preparation method for a dry film solder resist includes forming a predetermined photo-curable and heat-curable resin composition on a transparent carrier film having a surface on which a fine unevenness having an average roughness (Ra) of 200 nm to 2 ?m is formed; laminating the resin composition on a substrate to form a laminated structure in which the substrate, the resin composition, and the transparent carrier film are sequentially formed; exposing the resin composition and delaminating the transparent carrier film; and alkaline-developing the resin composition in a non-exposure part and performing heat-curing.
