Abstract
More simple and cost-effective shrinkage techniques for contact hole (C/H) are required instead of conventional technologies such as thermal flow, RELACS, SAFIER and CONPEAT with the aggressive reduction in size of devices. We have developed a new method, Coating Assisted Shrinkage of Space (CASS) process. This process simply coats polymer over the patterned wafer. It doesn't need a bake and rinse step for shrinkage. Sub-100 nm C/H patterns were successfully defined after coating CASS material with good profile.
