R1-1.9 Scenario IX – Pre-align Fails on Subsequent Substrate. User Clears Condition Prior to the Host Issuing the
Next LOAD-SUBSTRATE Command — The prober fails to pre-align a substrate while the host is processing a
substrate on the main chuck. The user manually aligns the substrate and presses Start on the prober console to clear
the alarm. The next LOAD-SUBSTRATE command from the host proceeds as normal.

R1-1.10 Scenario X – Pre-align Fails on Subsequent Substrate. User Fails to Clear the Condition Prior to the Host
Issuing the Next LOAD-SUBSTRATE Command — The prober fails to pre-align a substrate while the host is
processing a substrate on the main chuck. The user manually aligns the substrate but fails to complete the manual
alignment prior to the host issuing the LOAD-SUBSTRATE command. The Process State model transitions to the
PROCESSING BLOCKED state until the user clears the alarm. When the alarm is cleared, the Process State model
transitions to the HANDLING MATERIAL state and processing resumes as normal.

R1-1.11 Scenario XI – Correlation Substrate Testing
R1-1.11.1 Overview — This scenario describes the use of a correlation substrate. The correlation substrate is
loaded on the chuck to verify the test results for the current setup. From the Process/Control Job perspective,
correlation substrate testing is a normal task available to the host. Therefore, there are no job related collection
events associated with correlation testing.
R1-1.11.1.1 The correlation substrate is not part of a Process Job. The correlation substrate must be run using the
same recipe as the currently loaded process job.
R1-1.11.2 Pre-Conditions
R1-1.11.2.1 Job Setup — See Section R1-1.1.2.1
R1-1.11.2.2 Job Start — See Section R1-1.1.2.2.
