3 ALLOCATED Production Equipment: The last lot
allocation to the reticle by a preprocessing or
processing lot is removed because this lot
has been moved to another state OR the
equipment has been restarted.
Inspection Equipment: The inspection for
which the reticle was allocated has been
finished or has been cancelled.
Bare Reticle Stocker: The reticle has been
deselected for kitting.

15 Verification
15.1 Verification is the operation of comparing an actual value with an expected value. Verification may be
performed by either the host or the equipment, depending upon whether the host is using the Bind,
ReticleTransferJob, or PodNotification service or not.
15.1.1 If the host provides the expected value before the actual value is obtained by the production equipment, then
the production equipment shall perform the verification.
15.1.2 If the host does not provide the expected value before the actual value is read, then the production equipment
shall provide to the host, the information necessary for host based verification.
15.1.3 There are three values that are defined by Reticle and Pod Management that require verification: PodID, Pod
Slot Map, and ReticleID.
15.2 PodID Verification
15.2.1 Table 15 defines the methods for verifying the PodID.

Bind or
ReticleTransferJob
Service: The host
executes the Bind or
ReticleTransferJob
service to associate a
reticle pod load port
and a PodID.
Bind or ReticleTransferJob Service: The
production equipment reads the PodID from
the reticle pod, compares it to the podID
supplied with the Bind or ReticleTransferJob
service.
Verification Passed: Transition 6 of the
Reticle Pod State Model occurs. The
production equipment proceeds with
processing.
Verification Passed: None.

Verification Failed: The equipment initiates
Transition 12 of the reticle pod state model
then Transition 29 and the reticle pod object
created via the bind or ReticleTransferJob
service is destroyed. The equipment also
initiates Transition 3 of the reticle pod state
model and a reticle pod object with the PodID
equal to the one determined by the PodID
read is instantiated. The reticle pod shall not
be opened by the equipment until and unless
the ProceedWithPod service is received from
the host.
Verification Failed: The host uses
either the CancelPod service to force
the reticle pod to be readied for
unload, or indicates to the production
equipment that it may proceed with
the unexpected reticle pod, by
sending the ProceedWithPod service.
In both cases the PodID specified in
the service is equal to the one
determined by the PodID read.
PodNotification
Service: The host
executes the
PodNotification
service to inform the
equipment of the
future arrival of a pod
to an unspecified
reticle pod load port.
PodNotification Service: The production
equipment reads the PodID from the reticle
pod, compares it to the PodID supplied with a
PodNotification service.
Verification Passed: Transition 6 of the
Reticle Pod State Model occurs. The
production equipment proceeds with
processing.
Verification Passed: None.
Verification Failed: Not Applicable; because
there is no association between a reticle pod
load port and a reticle pod, equipment based
verification failure is not possible. If a reticle
pod that has not been instantiated arrives at a
load port, the equipment shall consider this as
host based verification.
Verification Failed: Not Applicable,
because there is no association
between a reticle pod load port and a
reticle pod, equipment based
verification failed is not possible. If
a reticle pod that has not been
instantiated arrives at a reticle pod
load port, the equipment shall
consider this as host based
verification.” The host will respond
with either a ProceedWithPod or a
CancelPod Service. (See Host Based
verification method).
Host Based None required, the
host may issue a
ReserveAtPort service.
The production equipment reads the PodID
and reports it to the host in an event report.
Following PodID read the equipment initiates
Transition 3 of the Reticle Pod State Model
and a reticle pod object with the PodID equal
to the one determined by the PodID read is
instantiated. The reticle pod shall not be
opened the equipment until and unless the
ProceedWithPod service is received from the
host.
Verification Passed: The host sends
a ProceedWithPod service indicating
the verification passed.
Verification Failed: The host uses
the CancelPod or CancelPodAtPort
service to force the equipment to
prepare the pod for unload
.

15.3 Slot Map Verification
15.3.1 Table 16 defines the methods for verification of the Reticle Pod Slot Map. Some user’s factory operations
may not require strict management of the slot map. In this case the user may use the host based verification method.

The host provides a
Slot Map with the
Bind,
PodNotification,
ReticleTransferJob,
or the
ProceedWithPod
service.
The production equipment
checks the
reticle pod slot
map and compares it to the
slot map supplied by the
host. Either Transition 14, or
15 of the Pod State Model
occurs.
Verification Passed: None, the production equipment
proceeds with the pod.
Verification Failed: If the host decides to cancel
processing, the host issues the CancelPod service. If the
host decides to continue processing, the host issues the
ProceedWithPod service.
Host Based None. The production equipment
checks the reticle
pod slot
map and reports it to the host
in an event report. The host
has the responsibility for
verifying the slot map.
Verification Passed: The host sends a ProceedWithPod
indicating the verification passed.
Verification Failed: If the host decides to cancel
processing, the host issues the CancelPod service. If the
host decides to continue processing, the host issues the
ProceedWithPod service.
