Dear All: Im working on silicon-glass bonding with polymer. Now I want to inspect the interface between silicon and glass. Though the glass is transparent for optical microscope inspection, the uncovered interface is better for me. Thus I need to etch the glass without hurt the polymer interface. Are there some good methods for this purpose? Hope for your help. Best Regards! Bugnie KAIST, ROK bugnie@163.com 2009-09-02
