Abstract
The dry development of sub-0.25 μm silylated resist features patterned at 193 nm was optimized in an oxygen plasma using a high-ion-density plasma etcher. Low pressure and low wafer temperature eliminate lateral resist loss, resulting in vertical profiles, linewidth fidelity, and large process latitudes for 0.175 μm silylated resist features.
