We use RF sputtering technique to deposit silicon oxide at a set heater
temperature of about 120C. To obtain the right crystal structure, the sputtered
oxide is annealed in oxygen atmosphere for 8 hours at a temperature of 600C. The
target that we are using now is from TMI, (Target Materials, INC), USA.

Hope this will help.

Plan Optik GmbH in Germany produces glass (e.g. Pyrex) wafers with holes.
The wafers can be from 100 microns (thickness) up to 5000 microns. The wafer
size can be from 1" to 12". The minimum hole diameter is approximately 500
microns (there is no maximum hole diameter). For that a newly developped,
numerically controlled, ultrasonic drilling process (so called USHD) is
used.

Hi all.

Anyone got an idea of how to make an Safe and Arm(S/A)
mechanism in weapon system based on MEMS. All input is appreciated.

Dear all,
does somebody know how to sputter silicon oxide films at low temperature for
a dielectric coating. Is there some literature available? Doe somebody know
a supplier of targets?
Any help is highly appreciated.

Best regards in advance
