发明名称 Edge bead remover for thick film photoresists
摘要 An edge bead remover for a photoresist composition disposed as a film on a surface, consisting essentially of a solvent mixture comprising from about 50 to about 80 parts by weight, based on the weight of the solvent mixture, of at least one di(C1-C3)alkyl carbonate and from about 20 to about 50 parts by weight, based on the weight of the solvent mixture, of cyclopentanone. A method is also provided for treating a photoresist composition film disposed on a surface which method comprises contacting the photoresist composition with a solvent mixture, in an amount sufficient to produce a substantially uniform film thickness of the photoresist composition across the surface, wherein the solvent mixture comprises from about 50 to about 80 parts by weight, based on the weight of the solvent mixture, of at least one di(C1-C3)alkyl carbonate and from about 20 to about 50 parts by weight, based on the weight of the solvent mixture, of cyclopentanone.
