Abstract: A resist composition is provided to stably separate a mold and extend the lifetime of the mold and to improve adhesion of a base layer and a resist pattern in an imprinting lithography process. A resist composition includes UV(ultraviolet) curable resin and an additive, containing an adhesion increasing agent for inducing a chemical combination of the UV curable resin and a coated layer. The adhesion increasing agent can be one of an epoxy-based compound or a urethane-based compound. The additive can include at least one of an initiator and a coupling agent.

Abstract: A soft mold resist for soft-lithography and a method for fabricating a liquid crystal display (LCD) device using the same where the soft mold includes a hydrophilic liquid prepolymer, a photoinitiator and a surface active agent, are provided. A soft mold (207a) is formed by applying the soft mold resist (205a) to a back plate (201) or a master plate and transferring a predefined pattern (B) from the master plate to the soft mold resist. A display is formed by applying the soft mold to an etch resist layer overlying a thin film and transferring the predefined pattern to the etch resist, then etching the thin film using the etch resist as a mask. Additional processing steps are carried out to form the LCD device.

Abstract: A covering layer is formed on red, green and blue color filters. A mold (17) is set up on the covering layer. The covering layer is first cured through the mold. The mold is removed from the covering layer. The covering layer is subjected to a second curing after the mold is removed. A surface on a glass substrate (11) is divided into color-filter areas (CA) and white- filter areas (WA).

Abstract: A method for fabricating a mold includes the steps of forming a photo-polymerizable resin layer between a master substrate and a transparent mold substrate, wherein a first pattern is formed on the master substrate; solidifying the resin layer by exposing the resin layer to a UV light through the transparent mold substrate; and forming a mold having a second pattern by separating the resin layer from the master substrate, wherein the second pattern is in a form of a recess on the resin layer at a portion corresponding to the first pattern and the resin layer being engaged with the mold substrate.

Abstract: A photo-polymerizable resin layer 25 is formed between a master substrate 21 in which a first pattern 23 is formed and a transparent mould substrate 27. The resin layer is hardened by exposing the resin layer to UV light through the transparent mould substrate. A mould having a second pattern 31 derived from the first pattern is obtained by separating the polymerized resin layer from the master substrate, with the resin layer being engaged with the transparent mould substrate.
