The most commonly modified parameters are shown on the first film parameters screen.
Additional parameters can be accessed by pressing Film Conds (film conditioning) or
Deposit Controls.

Scroll to the end of the list (Z-Factor), then scroll back up to Material. Press Edit to
scroll through the list of available materials. Notice that the Density and Z-Factor are
updated automatically as a new material appears.
Select the desired material and press Enter. You could change the Density and Z-
Factor for the selected material now, but it is unlikely those values are wrong. To add a
material name that is not listed, you must use the SQC-122c setup software.
Once the material is selected, set up the source parameters. Scroll to Output and
select the SQC-122c rear panel output that is connected to the source evaporation
supply. If a source pocket indexer is being used, assign it also.
Now assign the Max Power and Slew Rate appropriate for this material and your power
supply. For now, set both to 100%. Set them to lower values later if you find that small
power changes cause excessively large changes in deposition rate.
The SQC-122c can use multiple sensors to measure a film’s deposition rate and
thickness. If multiple sensors are selected, an average of the sensors is used. Set
each sensor that will be used to measure this film to ON. Alternately, you might want to
use a dual shuttered sensor in case of crystal failures. See the Film Menu section of
Chapter 3 for instructions on setting up a primary/secondary dual sensor.
