摘要：
The present invention relates to a novel polymer comprising at least one unit derived from an ethylenically unsaturated compound containing at least one cyano functionality and at least one nonaromatic cyclic unit. The novel polymer is particularly useful when used in a photoresist composition sensitive in the deep ultraviolet region.
