    摘要: A copolycarbonate having a high refractive index, a small birefringence, high processability and excellent transparency and an optical lens formed from the copolycarbonate.The copolycarbonate has a total content of a unit represented by the following formula (I) and a unit represented by the following formula (II) of not less than 80 mol % based on the total of all the recurring units, the molar ratio of the unit represented by the formula (I) to the unit represented by the formula (II) being in the range of 98:2 to 35:65. (wherein each of R1, R2, R3 and R4 is independently a hydrogen atom, alkyl group having 1 to 20 carbon atoms or the like. X is an alkylene group having 2 to 8 carbon atoms or the like. Each of m and n is independently an integer of 1 to 10.) (wherein each of R5, R6, R7 and R8 is independently a hydrogen atom, alkyl group having 1 to 20 carbon atoms or the like.)

    摘要: Anti-reflective compositions and methods of using these compositions to form circuits are provided. The compositions comprise a polymer dissolved or dispersed in a solvent system. Preferred polymers include polycarbonates, polysulfonyl esters, polycarbonate sulfones, and mixtures thereof. The compositions can be applied to a silicon wafer or other substrate to form a cured or hardened layer which is initially insoluble in typical photoresist developing solutions. Upon exposure to light, the cured or hardened layers become soluble in photoresist developing solutions so that the layer can be selectively removed along with the developed photoresist layer, thus eliminating the need for a separate removal step.
