 ==== DO's and DONT's ====
+Only use bare substrate in the plasma cleaner, all exceptions should be discussed.
-==== Checking system status and before starting ====
+  * Si
+  * SiO2
+  * glass/quartz
 ==== MANUAL ====
+  * Load samples on the sample tray
-==== Finishing up and leaving the system ====
+  * Start the vacuum pump while holding the door, make sure black valve is pointing down
+  * Pump down to <100mTorr
+  * Set black valve to the needle valve
+    * if needle valve is open the pressure should go to previous setpoint (check the logbook)
-==== Common problems, tips and tricks ====
+    * or change the setpoint
+  * Wait for pressure to stabilize
+  * set RF (low, mid or high)
+  * When plasma ignites start your timer
+  * Turn off RF when timer finishes
+  * Close black valve (valve pointing down)
+  * Pump down to <100mTorr to make sure etch products are removed from the chamber
+  * Stop the vacuum pump
+  * Turn black valve to the right to vent
+    * vent slowly to avoid samples flying around in the chamber
+  * Close black valve (valve pointing down)
+  * close the door
+  * write in the logbook: name, date, sample, process conditions, any remarks
