发明名称 Chemical compositions for improving photolithographic performance.
摘要 <p>Chemical compositions are presented that provide an increased rate of processing in a photolithography process in which a bleachable layer on top of a resist is bleached to produce a contact mask and then the resist is exposed through this contact mask. These compositions have increased oxygen permeability and increased solubility for a bleachable dye. Also, a class of dyes is presented that increase the process speed.</p>
