摘要

The subject of the presentation will be Alcatel's latest developments in deep silicon and oxidernetching for MEMS fabrication using an ICP system.rnThe obtained results of the study to eliminate the ARDE effect (Aspect Ratio DependentrnEtching), also called RIE lag, will be discussed.rnResults will be presented showing less than 1% etch depth variation between 10m and 200rnfn width silicon structures while maintaining excellent uniformity.rnAlcatel's new deep oxide etching ICP tool AMS 200 DE (Dielectric Etcher) has beenrnspecifically designed for deep oxide etching in MEMS & MOEMS application, so to meet therntypical etch requirements of SiO2, quartz and other glass-like materials.rnOutstanding etch results will be presented, including very high selectivity up to 30:1 tornPhotoresist Mask, with high SiO2 Etch Rate up to 0.5 m /min with excellent uniformity (
