Solvent mixtures for antireflective coating compositions for photoresists
摘要：
The invention relates to an antireflective coating composition capable of being coated beneath a photoresist layer, where the antireflective coating composition comprises a polymeric crosslinker and a solvent mixture, where the solvent mixture comprises at least one primary organic solvent and at least one secondary organic solvent selected from any of structures 1, 2 and 3, where, R1, R3, and R4, are selected from H and C1-C6 alkyl, and R2, R5, R6, R7, R8, and R9 are selected from C1-C6 alkyl, and n=1-5. The invention also relates to an antireflective coating composition capable of being coated beneath a photoresist layer, where the antireflective coating composition comprises a polymeric crosslinker and a solvent mixture, where the solvent mixture comprises at least 2 organic solvents, and where the antireflective coating composition has a liquid particle count at 0.2 micron of less than 100/ml after accelerated aging.
