+ | ===== Operating Guidelines ===== | ||
+ | - Add yourself to the Silane Vapor Deposition Rig Log | ||
+ | - Place your wafer inside the chamber. Check the O-ring seal. If dirty, wipe with a Kimwipe. | ||
+ | - Turn the vacuum on with the green switch. When the pressure reads about 15 inHg, turn the vacuum off and test the vacuum by waiting a minute or two and making sure the pressure reading stays steady. | ||
+ | - Turn the nitrogen on on the side of the fume hood. You only need to turn the knob once or twice. | ||
+ | - Purge the chamber of water and air. Open the nitrogen valve until the pressure reads about 5 inHg, then open the vacuum valve until the pressure reads 15 in Hg again, repeating five times. | ||
+ | - Open the two silane valves | ||
+ | - Flip the sign to “IN USE”. | ||
+ | - Close the fume hood and set a timer for 40 minutes. | ||
+ | - Update the logbook with your end time. | ||
+ | - When your timer goes off, close the silane valves (perpendicular). | ||
+ | - Open the nitrogen valve until the pressure reads 5 in Hg. Open the vacuum valve until 15 in Hg. Repeat 5 times to purge the chamber again. | ||
+ | - Remove your wafer. | ||
+ | - Flip the sign back to “AVAILABLE” and close the hood. | ||
