MDC-360C DEPOSITION CONTROLLER
FRONT PANEL DISPLAYS AND CONTROLS 2-1
2. FRONT PANEL DISPLAYS AND CONTROLS
The front panel is divided into two sections, the operating section and the
programming section. The left half of the panel is devoted to the operating
displays and controls. The right half is used for programming, viewing stored
processes, and displaying the status of the selected process.
2.1 OPERATING DISPLAYS
All of the operating displays are updated ten times per second unless the
controller is in the Abort mode. When in the Abort mode, the values of the
operating displays are held constant so the operator will know the values at the
time of the Abort. The controller will also flash the operating displays while in
Abort to alert the operator.
Figure 2-1 Operating Display
2.1.1 RATE
A three digit display with a floating decimal point is used to display deposition
rate in angstroms per second at a resolution of 0.1 Å/sec from 0 to 99.9 Å/sec, and
a resolution of 1.0 Å/sec for rates from 100 to 999 Å/sec.
2.1.2 POWER
A three digit display with a fixed decimal point displays percent of maximum
power with a resolution of 0.1% from 0 to 99.9%. This corresponds to the control
voltage range of 0 to 9.99 volts.
2.1.3 THICKNESS
Four digits with an autoranging decimal point display measured thickness in KÅ
with a resolution of 1 Å from 0 to 9.999 KÅ, a resolution of 10 Å from 10.00 KÅ
to 99.99 KÅ and a resolution of 100 Å from 100.0 KÅ to 999.9 KÅ.
2.1.4 LAYER NUMBER
Three digits display the layer number of the current process.
2.1.5 CRYSTAL HEALTH %
A two-digit display is used to show the health percentage of the active
sensor/crystal. If multiple sensors/crystals are active then the crystal with the
lowest health will be displayed. A fresh crystal starts out with a health of 99%.
