    摘要: A resist composition is provided comprising a polymer comprising recurring units having a hydroxyl group substituted with an acid labile group, an onium salt PAG capable of generating a sulfonic acid, imide acid or methide acid, and an onium salt PAG capable of generating a carboxylic acid. A resist film of the composition is improved in dissolution contrast during organic solvent development, and from which a hole pattern having minimized nano-edge roughness can be formed via positive/negative reversal.

    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.

    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.
