    摘要： The present invention provides a high sensitivity chemically amplified positive-working resist composition which eliminates edge roughness on pattern and provides an excellent resist pattern profile. A novel positive-working resist composition is provided comprising (A) a resin containing an alkali-soluble group protected by at least one of moieties containing alicyclic hydrocarbon represented by general formulae (pI) to (pVI) and having a monomer component content of 5% or less of the total pattern area as determined by gel permeation chromatography (GPC), which increases in its solution velocity with respect to an alkaline developer by the action of an acid and (B) a compound which is capable of generating an acid by irradiation with an active ray or radiation.

    摘要： A positive photoresist composition comprising a photo-acid gererator and a specific resin. The resin contains repeating units each having a group represented by formula (I): —SO2—O—R wherein R represents an optionally substituted alkyl, cycloalkyl, or alkenyl group and comes to have an increased rate of dissolution in an alkaline developing solution by the action of an acid, or contains alkali-soluble groups protected by partial structures containing an alicyclic hydrocarbon and represented by at least one of formulae (pI) to (pVI) defined in the specification and which decomposes by the action of an acid to have enhanced solubility in an alkali. The latter is used in combination with a compound which decomposes by the action of an acid to generate a sulfonic acid.

    摘要： A positive photosensitive composition comprising (A) a compound which generates an acid upon irradiation with an actinic ray or radiation, and (B-1) a resin having a group which is decomposed by the action of an acid to increase solubility in an alkaline developing solution and containing at least one structure represented by formulae (I), (II) and (III) as described in the specification or (B-2) a resin having at least one monovalent polyalicyclic group represented by formula (Ib) as described in the specification and a group which is decomposed by the action of an acid to increase solubility in an alkaline developing solution. The positive photosensitive composition containing the resin according to the present invention has high transmittance to far ultraviolet light particularly having a wavelength of 220 nm or less and exhibits good dry etching resistance. Further, the positive photosensitive composition exhibits high sensitivity, good resolution and good pattern profile when far ultraviolet light having a wavelength of 250 nm or less, particularly 220 nm or less (especially an ArF excimer laser beam) is employed as an exposure light source, and thus it can be effectively employed for the formation of fine pattern necessary for the production of semiconductor elements.

    摘要： When the number of pieces of error position information detected by using one symbol, of internal and external symbols constituting an error correcting code added to information data, which has a data sequence substantially corresponding to the reception order of the information data exceeds the erasure correcting ability based on the other symbol, error position information is selected upon weighting based on the continuity of the error position information in consideration of the fact that burst error position information exhibits high continuity. By selecting error position information upon weighting based on continuity, erasure correction, which cannot be performed in the prior art, can be performed.

    摘要： A positive photosensitive composition comprising:a compound represented by formula (I) or (I') and a compound represented by formula (II) as compounds which generate a sulfonic acid upon irradiation with actinic rays or radiation: ##STR1## The substituents in these formulae are as defined in the specification. The positive photosensitive composition has high sensitivity and high resolving power, undergoes neither a decrease in resist pattern line width nor the formation of a T-top resist pattern surface with the lapse of time from exposure to heat treatment, and exhibits less profile deterioration such as residual standing wave and collapse.
