    摘要: A resist composition contains as a base resin a polymer represented by the following formula and having a Mw of 1,000-500,000. R1 is H, methyl or CO2R2, R2 is alkyl, R3 is H, methyl or CH2CO2R2, at least one of R4 to R7 is a carboxyl or hydroxyl-containing monovalent hydrocarbon group, and the reminders are independently H or alkyl, at least one of R8 to R11 is a monovalent hydrocarbon group of 2 to 15 carbon atoms containing a —CO2— partial structure, and the reminders are independently H or alkyl, R12 is a polycyclic hydrocarbon group or an alkyl group containing such a polycyclic hydrocarbon group, R13 is an acid labile group, Z is a divalent group of atoms to construct a 5- or 6-membered ring which contains a carboxylate, carbonate or acid anhydride therein, k is 0 or 1, x is a number from more than 0 to 1, “a” to “d” are from 0 to less than 1, x+a+b+c+d=1. The resist composition has significantly improved resolution, substrate adhesiveness, and etching resistance and is very useful in precise microfabrication.

    摘要: A resist composition contains as a base resin a polymer comprising recurring units of the formula (1-1) or (1-2) and having a Mw of 1,000-500,000. R1 is H, methyl or CO2R2, R2 is a straight, branched or cyclic C1-15 alkyl group, R3 is hydrogen, methyl or CH2CO2R2, R4 is an acid labile group, i is an integer of 1 to 4, and k is equal to 0 or 1. The resist composition has significantly improved sensitivity, resolution and etching resistance and is very useful in precise microfabrication.

    摘要: A patterning process includes (1) coating a first positive resist composition onto a substrate, baking, exposing, post-exposure baking, and alkali developing to form a first resist pattern, (2) coating a resist-modifying composition onto the first resist pattern and heating to effect modifying treatment, and (3) coating a second positive resist composition, baking, exposing, post-exposure baking, and alkali developing to form a second resist pattern. The resist modifying composition comprises a base resin comprising recurring units having formula (1) wherein A1 is alkylene, R1 is H or methyl, R2 is alkyl or bond together to form a nitrogen-containing heterocycle, and an alcohol-based solvent.
