FRACTIONATED NOVOLAK RESIN FROM CRESOL-FORMALDEHYDE REACTION MIXTURE AND PHOTORESIST COMPOSITION THEREFROM |
摘要 |
The present invention provides a method for producing a film forming, fractionated novolak resin having consistent molecular weight and superior performance in photoresist composition, by isolating such novolak resin fractions without high temperature distillation. A method is also provided for producing photoresist composition from such a fractionated novolak resin and for producing semiconductor devices using such a photoresist composition.
