    摘要: There are provided steps of forming a lower resist layer on a patterning objective layer, forming an organic intermediate layer made of organic material, that contains no Si—O bond in its structure, on the lower resist layer, forming an upper resist layer made of alicyclic resin on the organic intermediate layer, forming a pattern by exposing/developing the upper resist layer, transferring the pattern of the upper resist layer onto the organic intermediate layer by etching the organic intermediate layer while using the upper resist layer as a mask, transferring a pattern of the organic intermediate layer onto the lower resist layer by etching the lower resist layer while using the organic intermediate layer as a mask, and etching the patterning objective layer while using the lower resist layer as a mask. Accordingly, a semiconductor device manufacturing method containing patterning steps employing a multi-layered resist structure, that is capable of suppressing deformation of the pattern of the upper resist layer formed of alicyclic compound, can be provided.

    摘要: A method for forming resist patterns comprising coating a resist comprising a polymeric or copolymeric compound having a repeating unit comprising a protected alkali-soluble group in which the protecting group is cleaved with an acid so that the compound is made alkali-soluble, and an acid generator capable of generating an acid upon the radiation exposure to a substrate to be fabricated, then pre-baking the formed resist film, successively selectively exposing the resist film, thereafter, developing a latent image with a developer containing an aqueous or alcoholic solution of a specified ammonium compound or morpholine compound. According to this method, crack formation and peeling of a pattern can be suppressed at the time of forming resist patterns.

    摘要: Alkali-developable, chemically amplified resist composition which comprises an alkali-insoluble, film-forming compound having a structural unit containing a protected alkali-soluble group in which unit a protective moiety of said protected alkali-soluble group is cleaved upon action of an acid generated from a photoacid generator used in combination with said compound, thereby releasing a protective moiety from the alkali-soluble group and converting said compound to an alkali-soluble one, and a photoacid generator capable of being decomposed upon exposure to a patterning radiation to thereby produce an acid capable of causing cleavage of said protective moiety. The resist composition is particularly suitable for excimer laser lithography using an alkaline developer, and the formed resist patterns can exhibit a high sensitivity and excellent dry etch resistance without swelling.
