ii) STOP buttons: Select to stop either pumping down or venting the
associated chamber. Note that the STOP button must be selected before
venting to ensure the correct sequencing of the valves.
iii) VENT buttons: Select to vent the associated chamber.
b) Mimics of all valves showing open/closed status (coloured green when open, red
when closed).
c) Rotary/dry pump controls. Clicking on a rotary vane/dry pump mimic button will
switch the associated pump on or off (a running rotary pump is indicated by
animation).
d) Transfer arm, Wafer lift and Wafer clamp status panel. Displays indicators for ARM
HOME, ARM EXTENDED and ARM FAULT (illuminated when active). Also displays
WAFER LIFT and WAFER CLAMP status (up, down, moving or fault). See the
following table.
Message Meaning
UP The UP microswitch is detected as active.
DOWN The DOWN microswitch is detected as active.
MOVING Both microswitches are detected as inactive.
FAULT Both microswitches are detected as active.
e) The run status of the turbo pump is indicated by an associated message panel
containing an indicator. While the turbo pump is running up to speed, the message
‘accelerating’ is displayed and the indicator is flashing yellow. While the turbo pump
is at its operating speed, the message ‘at speed’ is displayed and the indicator is
green.
f) A SET BASE PRESSURE button. Select to set the Process Chamber Base Pressure.
g) Context related message panels for the process chamber, Automatic load lock and
wafer transfer progress.
h) ‘Ready for transfer’ indicators (WX) - displayed when the associated chamber or load
lock is evacuated and ready for wafer transfers.

Fig 5.13: Robot control page
The Robot Control page is used to manually transfer a wafer between chambers (when
operating in automatic mode, i.e. running a recipe, wafers are transferred automatically). The
location of the wafer is indicated by a green wafer indicator. The arrowed path shows the
currently available wafer destination.
The page provides the following features:

Displays the wafer location and possible wafer destination.
To transfer a wafer from the Automatic load lock to the process chamber to carry out a
manual process, use the following steps:
1) Click on the Automatic load lock wafer mimic. The blue arrowed path is displayed
showing the available destination.
