RIE or ICP? ------Original Message------ From: Paul SunalTo: General MEMS discussion ReplyTo: Paul Sunal Re: [mems-talk] etch rate of Ag in XeF2 Jan 7, 2011 20:06 Tricia, It does! But in a complex manner. I don't have the etch rate, but I know from experience that the Ag undergoes some sort of chemical reaction and then etches away. It is slower than the etch rate of silicon, but still fairly fast. Regards, Paul
