Hello, I'm trying to find a way to etch aluminum oxide without attacking titanium. Several common Al2O3 etchant I tried all etch Ti quite fast as well, such as NaOH, H3PO4, NH4OH, etc. Can anyone suggest a way to achieve selective etching between these two? Any advice will be greatly appreciated! Thank you very much! -- Travis _______________________________________________ Hosted by the MEMS and Nanotechnology Exchange, the country's leading provider of MEMS and Nanotechnology design and fabrication services.
