    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: Acid-catalyzed positive resist compositions which are imageable with 193 nm radiation and/or possibly other radiation and are developable to form resist structures of improved development characteristics and improved etch resistance are enabled by the use of resist compositions containing imaging polymer component comprising an acid-sensitive polymer having a monomeric unit with a pendant group containing a remote acid labile moiety.
