    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: The present invention provides ester group-containing tertiary amine compounds of the formula (R1OCH2CH2)nN(CH2CH2CO2R2)3-n which, when used as additives in chemical amplification photolithography, can yield photoresists having a high resolution and an excellent focus margin. The present invention also provides a process comprising the step of subjecting a primary or secondary amine compound to Michael addition to an acrylic ester compound; a process comprising the steps of subjecting monoethanolamine or diethanolamine to Michael addition to an acrylic ester compound so as to form an ester group-containing amine compound and introducing a R1 group to the resultant ester group-containing amine compound; and a process comprising the step of effecting the ester exchange reaction of an ester group-containing tertiary amine with R2OH.
