MonacoHi,

I am a PhD student working on a new electroless etch stop technique.

Could you help me with the following problem:

What kind of metal process do I need to get a gold layer on silicon

which survives KOH or TMAH at high temperatures. We have tried

evaporated Au/Cr but that comes of after a few hours?

If you can help me please e-mail:

Thanks


Try out Ti/W as a first layer. It works for Pt electrodes in KOH....
