摘要
The effect of process conditions on the performance of the chemically amplified radiation resist RAY-PF has been examined for both X-ray and E-beam application. It is found that mandatory atmospheric holding times for the catalytic reaction can be made redundant by the introduction of a post exposure bake at moderate temperature, yielding high exposure latitude, good linearity and a reduction of time-dependent effects. In particular, metal-ion free developers yield highly vertical resist sidewalls even for high overdoses. Enhanced dry-etch stability and linearity may be obtained by means of an optimized DUV hardening process.
