摘要： The photosensitive composition, which is suitable as a photoresist material in fine patterning works for the manufacture of semiconductor devices, contains, as a photoextinctive agent, a combination of an alkali-insoluble dye and an alkali-soluble dye each having absorptivity of light in the wavelength region from 230 to 500 nm in a specified amount and in a specified ratio between them. By virtue of the formulation of combined dyes, the undesirable phenomenon of halation by the underlying aluminum coating layer on the substrate surface is greatly decreased so that patterned resist layer obtained with the composition is a high-fidelity reproduction of the original pattern even in a submicron range of fineness with good rectangularity of the cross sectional form of the patterned lines.

摘要： Proposed is an aqueous developer solution for an alkali-developable photoresist composition which contains, besides a water-soluble organic basic compound such as tetramethyl ammonium hydroxide and an anionic or non-ionic surface active agent as conventional ingredients in the prior art developwer solutions, an inorganic ammonium salt such as ammonium sulfate, ammonium phosphates and ammonium borates in a limited amount. By virtue of this unique additive, the developer solution is advantageous in respect of the absence of any scums on the patterned resist layer obtained by the development treatment therewith as well as quite good orthogonality in the cross sectional profile of line-patterned resist layer in addition to the greatly improved latitude in the light exposure dose and range of focusing depth in the light-exposure process of the resist layer with ultraviolet light.

摘要： Proposed is a novel method for the formation of a protective coating film having a pencil hardness of up to 9 H on the surface of various substrates or, in particular, electronic parts such as color filters and liquid crystal display panels. The method comprises: coating the surface with a liquid coating composition of which the principal ingredient is a partial cohydrolysis-condensation product of a tetraalkoxy silane, e.g., tetraethoxy silane, and a functional alkoxy silane, e.g., 3-methacryloxypropyl trimethoxy silane, and drying and heating the coating layer to effect complete curing. The hardness of the cured protective film can be increased by admixing the liquid coating composition with a finely divided inorganic filler such as a colloidal silica. It is optional that the functional alkoxy silane is subjected to the cohydrolysis reaction after it is polymerized alone or after it is copolymerized with a polyfunctional acrylic monomer.

摘要： Although the positive-working photoresist composition comprises a phenolic novolac resin as the film-forming component and a known photosensitizing compound as in conventional compositions, the novolac resin is prepared from a specific mixture of two classes of phenolic compounds including, one, phenol, cresols and/or resorcinol and, the other, one or more of the phenolic compounds having a nucleus-substituting group selected from allyloxy, allyloxymethyl, allyl dimethyl silyl, 2-(allyl dimethyl silyl) ethoxy, cinnamoyl, acryloyl and methacryloyl groups. By virtue of this unique combination to give the phenolic moiety in the novolac resin, the photoresist composition has markedly improved heat resistance as well as stability against plasma in dry etching so that the composition can give a patterned photoresist layer with extreme fineness having high fidelity to the mask pattern.
