12.7.3 Converting wafer supports from 8" wafer stretchers to 12" wafer stretchers
In order to process the different wafer sizes (8" and 12") on the SIPLACE SWS wafer stretcher, you
need to convert the SIPLACE SWS wafer stretcher.
You can order the SIPLACE SWS wafer stretcher in the following configurations:
●
[00519717-xx] 12" wafer expander
and optional
[03079734-xx] 8" retrofit kit
or
●
[00519719-xx] 8" wafer expander
and optional
[00519720-xx] 12" retrofit kit
The conversion from an 8" to a 12" wafer support is described below (see also 12.7.3.4 "Difference
when converting the 12" to the 8"" [}319]).
12.7.3.1 Retrofit kit parts: 12" wafer expander
Fig.439:

► Finish all ongoing processes in the SWS module.
► Move the wafer table to the change position.
► From the view, select Manual Operation -> Wafer Handling Systems -> Go to Change Po-
sition.
► Open the clamp.
► From the view, select Manual Operation -> Wafer Handling Systems -> Open Wafer
Clamp.
ð The clamping ring will open and the expansion ring will move downwards.
► Open the expander.
► From the view, select Manual Operation -> Wafer Handling Systems -> Release Ex-
pander.
ð The downholder plate will move upwards.
► From the view, select Production -> Miscellaneous and click the red "off" button there.
ð Shut down the SWS GUI and Linux properly.
► Switch off the SWS at the main switch.
CAUTION
Avoid damage to the gripper
When working on the wafer support, the gripper could be damaged.
► Push the gripper towards the wafer lift and out of the working area for the wafer sup-
port.
