Abstract:
The present invention relates to a printing element comprising at least one polymer layer on a substrate which has photoimageable constituents and a chemically functionalized polymer to make the polymer layer either more hydrophobic or hydrophilic. In one embodiment of the present invention, the printing element comprises two adjacent polymer layers on a substrate in which the photoimaged layer comprises a polymer chemically modified with hydrophobic fluoroalkyl side groups to provide differential wetting with hydrophilic inks.
Abstract:
Microstructures are fabricated by impinging a radiation beam, such as a laser beam, through a substrate that is transparent to the laser beam, into a negative photoresist layer on the substrate. The negative photoresist layer may be subsequently developed to provide a master for optical and/or mechanical microstructures. Related systems, microstructure products and microstructure masters also are disclosed.

PURPOSE: A mold, a method for manufacturing the mold and a method for forming a pattern using the mold are provided to separate the mold from a resist layer after forming a pattern by forming the mold with a polymer layer. CONSTITUTION: A primary body(45) includes a surface with a convex part(41) and a concave part(43) and composed of polymeric material. A polymer layer(50) is formed on the primary body and is composed of a copolymer with an amine group. The polymer layer includes a hydrophobic functional group on a surface. A hydrophilic function group is formed on the primary body by an ozone treatment or an UV treatment.
Abstract:
A method of nano imprinting for microstructures is provided to completely correspond to the microstructures of photoresist in the intaglio parts of the mold and to prevent the effect of external environment. The method of nano imprinting for microstructures comprises the step of forming holes and the step of performing imprint. The step of forming the holes is performed in order to form holes on the concave parts of the mold(500). The concave part of the mold is exposed to outside. The step of performing the imprint is performed in order to transcribe the concave parts of the mold on the semiconductor substrate. The semiconductor substrate has photoresist. The concave part of the molds is imprinted on photoresist. In this case, the hole of the molds prevent the generation of the vacancy between the concave parts of the mold and microstructures of photoresist.

Abstract:
A manufacturing method of a conductive organic matter electrode is provided to reduce damage and property due to acid, solvent, etchant, and developer by forming a conductivity organic compound without a photolithographic process. A photoresist is coated on a silicon substrate, and a pattern is formed through a photolithographic process. A positive or negative PR is coated on the silicon substrate which is pattered by an etching the substrate. A mold frame is formed by coating PDMS(polydimethylsiloxane) on the substrate. A PDMS mold is formed on the substrate by a drying process. The silicon substrate is separated from the PMDS mold which is fixed on an object to be transferred. A transfer substrate is made by a plastic or the metal substrate.
Abstract:
A fabricating method of a roll stamp using imprint lithography is provided to form a fine pattern without a joint at low cost. A flat stamp having a pattern on one surface is attached to a roll stamp including a resin layer coated on the circumference(S21). The pattern of the flat stamp is transferred on the roll stamp by rotating the roll stamp in one direction on one surface of the flat stamp(S22). The resin layer of the roll stamp including the transferred pattern is hardened(S23). The roll stamp is etched by using the resin layer of the roll stamp as an etching barrier(S24). An intermediate layer and the resin layer are sequentially laminated on the circumference of the roll stamp.
