Using the Carrier Station Controller 4-7
Wafer Time Limit Feature
To ensure optimum performance, as well as to help prevent possible structural or mechanical wafer
failures, Integral Wafers that are intended for use in certain processes or applications are equipped
with a built-in time limit feature. When the maximum recommended operating time has been
reached, the wafer will automatically cease to operate. Refer to your wafer’s specifications for
environmental operational limits and allotted usage hours.
The Measurement tab portion of the Controller program displays the remaining usage time
available to your wafer as shown in Figure 4-9.
Figure 4-9. Usage Time Remaining
When a wafer is approaching its final deployment, an alert box will appear indicating that the
maximum recommended operating time has almost elapsed. As long as there is available usage
time left, the Controller program will allow you to start a survey and deploy the wafer for a normal
measurement activity.
