Michael:

Our company is involved with various wet/dry chemical etching techniques,
specifically geared towards MEMS application. We have been conducting
extensive R&D work in the area of selective etching, generating silicon
membranes, maskless implantation technique, FIB based micromachining and FIB
based Ultra high density data-storage techniques. We would be more than
willing to do some work for your company on selective etching of PSG and
other materials. We also have the capability and expertise to build custom
low cost wet chemistry setup. I would really appreciate it if you could send
me more details as to what exactly you are looking for. Thank you and am
looking forward to hearing from you soon.

Regards
Jayant Neogi
