REVENUE STABILITY; MODEST RATE INCREASES LIMIT RATE BASE PRESSURE
In this study we have discussed the deposition of gallium nitride layer over silica nanosprings in a vacuum chamber with a base pressure of nearly 100 mtorr at a temperature of 425 [degrees]C using trimethylgallium and ammonia gas as precursors.
"We recently jacked up the base pressure levels for this line in efforts to provide cleaning professionals with the most power and features in this machine class," explained Daimer.com press spokesman Matthew Baratta.
The application uses the pump to reduce water vapor partial pressure, allowing faster product throughput, reducing base pressure and pump-down time.
The typical base pressure measured by a gauge near the turbomolecular pump is 3 X [10.sup.-5] Pa.
