Hi, does anybody has expierence about process parametes (O2/CHF3) to etch with RIE in SiO2 to get a 45 degree profile. The process should tend to isotrop etching. Other question is to find a Resist which is wear-resistant in RIE to etch in SiO2 405m deep ? I hope that somebody have a idee ? > ************************************************ > Martin Priester > Alcatel SEL AG, Dept.
