    摘要: A thermal acid generator of generating an acid on heating above 100° C. has formula: CF3CH(OCOR)CF2SO3−(R1)4N+ wherein R is alkyl or aryl, R1 is hydrogen, alkyl, alkenyl, oxoalkyl, aryl, aralkyl or aryloxoalkyl, or R1 may bond together to form a ring with N. The sulfonic acid generated possesses an ester site within molecule so that less bulky acyl groups to bulky groups may be incorporated therein. The thermal acid generator provides a sufficient acid strength, is less volatile due to a high molecular weight, and ensures film formation. Upon disposal of used resist liquid, it may be converted into low accumulative compounds.

    摘要: Although use of a nitrogen-containing compound as a basic compound component of a resist composition makes it possible to ease the T-top problem at an acid dissociation constant pKa falling within a range of 2 to 6, it is accompanied with the problem that the reaction, that is, acid diffusion upon use of a highly-reactive acid-labile group cannot be controlled. In order to overcome this problem, one or more basic compounds selected from those represented by the following formulas (I) to (III) and (1) to (4) are employed.

    摘要: The process forms a pattern by applying a resist composition onto a substrate to form a resist film, baking, exposure, post-exposure baking, and development. The resist composition comprises a polymer comprising recurring units having an acid labile group and substantially insoluble in alkaline developer, a PAG, a PBG capable of generating an amino group, a quencher for neutralizing the acid from PAG for inactivation, and an organic solvent. A total amount of amino groups from the quencher and PBG is greater than an amount of acid from PAG. An unexposed region and an over-exposed region are not dissolved in developer whereas only an intermediate exposure dose region is dissolved in developer. Resolution is doubled by splitting a single line into two through single exposure and development.
