WebMar 10, 2006 · For gate patterning, a resist trim step is often utilized prior to etching a hardmask and polysilicon. During each etch step the resist line-end is quickly eroded due to the sloped profile. In this paper, we present a novel post-develop processing technique for improving the line-end profile of patterned photoresist. This improvement in the ...
