    Abstract: PROBLEM TO BE SOLVED: To obtain high resolution and superior stability by incorporating a mix of at least two kinds of miscible polymer resins soluble in an aqueous base to make it useful for the blend of a positive type resist. SOLUTION: One of polymer resins soluble in an aq. base is partially protected with protective groups, having high activation energy and the other of the polymer resins soluble in an aqueous base is partially protected with protective groups having low activation energy. The polymer resin to be used is a homopolymer which is soluble in an alkali solution after being deprotected or a multiple polymer containing two or more kinds of repeating monomeric units e.g. a copolymer or a terpolymer and contains polar functional groups which ionize readily. The polar functional groups of the polymer resins are hydroxyl or carboxyl groups. The homopolymer which can be used as the polymer resin is especially preferably polyhydroxystyrene(PHS), and the para-type is most preferable.

    Abstract: The present invention relates to a photoresist composition capable of negative development and a pattern forming method using the photoresist composition. The photoresist composition includes an imaging polymer and a radiation sensitive acid generator. The imaging polymer includes a first monomelic unit having a pendant acid labile moiety and a second monomelic unit containing a reactive ether moiety, an isocyanide moiety or an isocyanate moiety. The patterning forming method utilizes an organic solvent developer to selectively remove unexposed regions of a photoresist layer of the photoresist composition to form a patterned structure in the photoresist layer. The photoresist composition and the pattern forming method are especially useful for forming material patterns on a semiconductor substrate using 193nm (ArF) lithography.

    Abstract: The present invention discloses an antireflective coating composition for applying between a substrate surface and a positive photoresist composition. The antireflective coating composition is developable in an aqueous alkaline developer. The antireflective coating composition comprises a polymer, which comprises at least one monomer unit containing one or more moieties selected from the group consisting of a lactone, maleimide, and an N-alkyl maleimide; and at least one monomer unit containing one or more absorbing moieties. The polymer does not comprise an acid labile group. The present invention also discloses a method of forming and transferring a relief image by using the inventive antireflective coating composition in photolithography.

    Abstract: PROBLEM TO BE SOLVED: To provide a method to mitigate resist pattern critical dimension variation in a double-exposure process.
    SOLUTION: The method to mitigate resist pattern critical dimension (CD) variation in a double-exposure process generally includes steps of: forming a photoresist layer over a substrate; exposing the photoresist layer to a first radiation; developing the photoresist layer to form a first pattern in the photoresist layer; forming a topcoat layer over the photoresist layer; exposing the topcoat layer and the photoresist layer to a second radiation; removing the topcoat layer; and developing the photoresist layer to form a second pattern in the photoresist layer.
