Hi, everyone:
I have one question. I want to remove the bulk Si from SOI with my
sample(1.5cm*1.5cm),I used the KOH to etch the Si, but KOH is easy to
attact the sample after 2-3 hrs using black Wax covered sample. I would
like to use the deep RIE to
remove the bulk Si, would you tell me which RIE equipment can etch Si from
small
piece samples?
Thank you very much.
