Paper Abstract
We investigate an all dry etching process of the development-free vapor photolithography (DFVP) with 315 XeF excimer laser. After masked exposure, SiO2 on a silicon wafer and beneath a photoaccelerator polymer layer can be directly etched by etching vapor which is a mixture of HF, water and N2. Ultimately, patterns with 0.4 micron resolution were obtained. We have investigated the effect of the etching temperature and time, exposure energy and 5-ni-troacenaphthene concentration on the resolution and discussed the mechanism of DFVP.
