R2-6 Scenario 6 — Dispatch List Based Scheduler/Dispatcher, Stocker is managed by Scheduling Component
R2-6.1 Dispatch list based. EQ1->Stocker->EQ2. After lot 1 processing on EQ1 is finished, Scheduler assigns lot
1 to EQ2. FO checks the EQ2 port status and finds the available port. Scheduler makes the logistic decision to
transfer lot 1 “from EQ1 to Stocker 2” instead of “from EQ1 to EQ2”. Scheduler assigns lots to Stocker when the
next equipment is not available. In this scenario 6, the separate transfers “from EQ1 to Stocker 2” and “from
Stocker 2 to EQ2” are described.

RELATED INFORMATION 3
ASSUMED CASE OF SCHEDULER/DISPATCHER
NOTE: This related information is not an official part of SEMI E105. This related information was approved for publication by
full letter ballot procedures on February 1, 2001.
The assumed two cases of scheduler/dispatcher were used to have an analysis and to make scenarios when the
interfaces defined in SEMI E105 ware developed. This related information describes the assumed two case of
scheduler/dispatcher to make easier for the standard user to understand SEMI E105. SEMI E105 does not limit the
case of Scheduler/Dispatcher to these two assumed scheduler/dispatcher.
R3-1 Dispatch List Based Scheduler/Dispatcher
R3-1.1 Basic Functions
Dispatch List Based Scheduler/Dispatcher has a waiting lots list in each operation and has a capability to prioritize
the existing lots.

Dispatch List Based S/D keeps the waiting Lot
List on each operation. The waiting Lot List is
the calculated result based on the rule provided by
the supplier
Decision made by Dispatch List Based S/D. Dispatch
List Based S/D sends one Lot (Batch) to FO as a
decision.
