    摘要: Provided are a mask pattern including a silicon-containing self-assembled molecular layer, a method of forming the same, and a method of fabricating a semiconductor device. The mask pattern includes a resist pattern formed on a semiconductor substrate and the self-assembled molecular layer formed on the resist pattern. The self-assembled molecular layer has a silica network formed by a sol-gel reaction. To form the mask pattern, first, the resist pattern is formed with openings on an underlayer covering the substrate to expose the underlayer to a first width. Then, the self-assembled molecular layer is selectively formed only on a surface of the resist pattern to expose the underlayer to a second width smaller than the first width. The underlayer is etched by using the resist pattern and the self-assembled molecular layer as an etching mask to obtain a fine pattern.

    摘要: Provided are a variety of monomers suitable of producing photosensitive polymers, that are in turn, useful in photoresist compositions, through radical (cationic) polymerization including at least one multi-ring alkenyl ethers and one α-fluorinated acrylate. The resulting photoresist compositions exhibit both acceptable resistance to dry etching processing and light transmittance suitable for use with various light sources such as KrF excimer lasers, ArF excimer lasers or F2 excimer lasers, in a photolithography process to produce fine photoresist patterns. In addition to the multi-ring alkenyl ethers and α-fluorinated acrylates, additional monomers comprising one or more cyclic aliphatic and heterocyclic compounds, both unsubstituted and substituted, in particular dihydropyrans, may be incorporated into the photosensitive polymers. Photosensitive polymers can then be produced by combining these various monomer units to form copolymers, terpolymers and higher order polymers, an exemplary embodiment of which may be generally represented by the formula V:
