Can anyone please tell me what resist I should be using as a mask for etching Silver? Also what is the solution suitable for etching Silver. I have come across two types of solutions for etching Silver, one is an acid mixture called Dilute Metal Etch - HNO3+H3PO4+CH3COOH and another called Base Etch - NH4OH+H2O2+CH3OH. But these solutions also developed the resist I used (PMMA). Please let me know. Thanks Sreemanth
