    摘要: The present invention relates to a polymer prepared by synthesizing monomer having a derivative of cholic acid, deoxycholic acid or lithocholic acid bonded to norbornene, and then homopolymerizing these monomer, copolymerizing these monomer with maleic anhydride, or copolymerizing these monomer, maleic anhydride and 2-hydroxyethyl 5-norbornene-2-carboxylate and/or 5-norbornene-2carboxylic acid, and its use as a photoresist. The polymer synthesized according to the present invention is dissolved in a solvent, together with a photo-acid generator, and filtered through a filter to make a photoresist solution which can be used to produce a lithographic image on a silicon wafer.

    摘要: Organometal-containing acrylate or methacrylate derivatives and photoresists comprising the polymers thereof. Unlike conventional matrix polymers of photoresist, the polymers induce a difference in silicon content between exposed regions and unexposed regions of photoresists by releasing their silicon-containing side chains with the aid of acid in a chemical amplification manner. The difference in silicon content causes the exposed regions to be etched at a different rate from that of the unexposed regions under oxygen plasma. Thus, the photoresist material makes it possible to use a microlithographic process comprising a dry development step which can advantageously prevent the deformation or collapse of patterns which is aggravated as their aspect ratio increases, as well as the photoresist is economically more favorable than a top surface imaging system to which silylation on its top surface or a multi-level resist system to which wet development on its top layer must be applied, because the microlithographic process is very simple and no solvent is released.
