Positive radiation sensitive resist terpolymers
摘要:
This invention relates to novel terpolymers of 3-methylcyclopentene, an omega alkynoic acid and sulfur dioxide. Positive radiation sensitive films prepared from the subject terpolymers adhere well to the substrate, demonstrate resistance to cracking and erosion during development and possess excellent edge definition.
