Dear all, I am trying to etch si in TMAH solution.I have very small chips(not wafer) to be etched.As we need to have mild stirring for the etchant solution,i was wondering how to place my chips in the etchant solution. Is there anyway that i can etch small chips in TMAH solution.I want to know if there is any vendor who can supply me epoxy so that i can attach my chips to any glass substrate and cure them which also protects the backside of the chips.I need epoxy that should not change PH of the solution as the etch process is highly sensitive to the change in PH values. Your suggestions would be highly grateful. Thanks Kris __________________________________ Do you Yahoo!? SBC Yahoo! DSL - Now only $29.95 per month! http://sbc.yahoo.com
