5 Ordering Information
5.1 Intended Use
— This standard is intended to specify reticle carriers over a reasonable lifetime of use, not just
those in new condition. For this reason, the purchaser should specify a time period and the number and type of uses
SEMI E112-0305 © SEMI 2001, 2005 3
to which the carriers will be put. It is under these conditions that the carriers must remain in compliance with the
requirements listed in §6.
5.2 Reticle Thickness — The purchaser needs to specify the reticle thickness to be accommodated in the MRSP150.
5.3 Optional Features — The purchaser needs to specify whether optional components (identified in §2) are
required.
5.4 Temperature Ranges — The purchaser needs to specify two sets of temperatures to which the MRSP150s might
be exposed. An operating temperature range is the set of environmental temperatures in which the MRSP150s will
remain in compliance with the requirements listed in §6. A temporary temperature range is the set of environmental
temperatures to which the pods can be exposed such that when the MRSP150s return to the operating temperature
range, the MRSP150s will be in compliance with the requirements listed in §6. Limits on exposure times to elevated
temperatures should be specified.
5.5 Electrostatic Dissipation — The end user may require a continuous path to ground from the reticle to the carrier
registration and handling features. The purchaser needs to specify whether electrostatic dissipation is required.
5.6 Contamination Requirements — The purchaser needs to specify their contamination requirements.
6 Requirements
6.1 Symmetry — Most of the dimensions of the MRSP150 are determined with respect to the three orthogonal
reference planes defined in this document: the facial reference plane, the horizontal reference plane and the bilateral
reference plane. All dimensions are symmetric about the bilateral reference plane.
6.2 Door — The pod door, and its frame on the bottom of the pod, must be compatible with a port which conforms
to SEMI E19.3.
6.3 Numbering — The reticles are numbered in increasing order from bottom to top (so the bottom reticle is reticle
number 1, to the top reticle which is reticle number 6).
6.4 Positioning — The nominal reticle seating planes are defined by z291 through z296 as shown in Figure 4 and
Table 2. The entire bottom surface of a reticle must lie within the z276 dimension of its nominal seating plane
shown in Figure 6 and Table 2.
6.5 Reticle Contact Surfaces — The reticle contact surfaces are the only 4 locations where the MRSP150 may
contact the pellicle side of the reticle. These surfaces are shown in Figures 8 and 9 with dimensions given in
Table 2. The contact surfaces are defined by x245, x246, y233, y234 and y235.
6.6 Reticle Capture — When the carrier is closed, a bisecting plane through the reticle, parallel to the bilateral
reference plane must be within x114 of the bilateral reference plane of the load port when the reticle is seated in the
carrier. A bisecting plane through the reticle, parallel to the facial reference plane must be within y228 of the facial
reference plane of the load port when the reticle is seated in the carrier.
6.7 Exclusion Volumes — The interior of the MRSP150 must never intrude into the pellicle exclusion volume, and
must not intrude into the end-effector exclusion volumes, lift clearance exclusion volumes or safety rail exclusion
volumes when the carrier is open.
6.7.1 End-Effector Exclusion Volumes — Volumes in an opened pod which must be free for the end-effector to
enter and handle the reticle as defined by x238, x239, x240, y227, y232, y238, z297, z299, z302 (first reticle) and
z300 (second through sixth reticle). No obstructions should exist in the end-effector exclusion volumes which
extend in the y direction (normal to the facial reference plane.) Table 2 defines the dimensions for the end-effector
exclusion volumes shown in Figures 4, 6, 7 and 8.
6.7.2 Pellicle Exclusion Volume — Volume in the pod below the reticle which must remain free from intrusion to
accommodate the pellicle mounted on the reticle. No obstructions should exist in the pellicle exclusion volume as
defined by x119, z290 (first reticle) and the previous reticle lift clearance exclusion volume (second through sixth
reticle) which extends in the y direction (normal to the facial reference plane). The pellicle exclusion volume is
defined in Table 2 and shown in Figure 4.
6.7.3 Reticle Lift Clearance Exclusion Volumes — Volumes in an opened pod which must be free to allow the end-
effector to lift and handle the reticles, as defined by x243, z298 and z311 (sixth reticle) as shown in Table 2 and
SEMI E112-0305 © SEMI 2001, 2005 4
Figures 4 and 6. No obstructions should exist in the reticle lift clearance exclusion volumes which extend in the y
direction (normal to the facial reference plane).
6.7.4 Safety Rail Exclusion Volumes — Volumes in an opened pod which must remain free from intrusion to
accommodate safety rails which may be used on end-effectors to protect the edge of the reticle during handling. No
obstructions should exist in the safety rail exclusion volumes which extend in the y direction (normal to the facial
reference plane) as defined by x241 and z301 in Table 2 and shown in Figure 4.
6.7.5 Rear Retainer Volume — Volume in an opened pod in which any reticle rear retainer must exist. The volume
is defined by x242 and y226 as shown in Figure 7 and Table 2.
NOTE 1: This volume is never to be accessed by an end-effector.
6.7.6 Reticle Backstops — The interior of the MRSP150 shall have reticle backstops which may be used by end-
effectors to position the reticle when being removed from the MRSP150.
NOTE 2: These are the minimum required backstops, the backstops may be larger than this minimum specification, occupying
any part of the rear retainer volume. The dimensions are defined by x249, x250, y239 and z314 as shown in Table 2 and in
Figure 7.
6.7.7 RFID Placement Zone — Zone in the pod where the RFID transponder is placed, which may be used for RF
communications during reticle handling. The entire RFID transponder must be positioned within the zone defined by
x251, x252, y239, y240, z308, z315, z316 in Table 2 and shown in Figures 1, 3, 11. Pod suppliers may also place
other features in this placement zone (such as the pod wall, RFID transponder support brackets, etc).
6.8 External Dimensions — Figures 1, 2, 3, 5 and 10 show, respectively, the external top view, a detail, the rear
view, the robotic handling flange and the conveyor rails of the MRSP150. Table 2 defines the external dimensions
of the MRSP150.
6.9 Internal Dimensions — Figures 4, 6 and 7 show internal dimensions of the MRSP150. Table 2 defines the
internal dimensions of the MRSP150.
6.10 Robotic Handling Flange — On the top of the pod is an optional robotic handling flange for automated
manipulation of the MRSP150. Figures 1, 3 and 5 show dimensions for the robotic handling flange. Table 2 defines
the dimensions for the robotic handling flange.
6.11 Recess — Surface on the top of the pod defined by dimensions x100, y106 and z281. Figures 1 and 3 show
dimension for the recess. The recess provides clearance for use of robotic handling flange.
NOTE 3: The raised surface around the recess is not required.
6.12 Side Handling Flanges — On the sides of the pod parallel to the bilateral reference plane are optional handling
flanges for automated manipulation of the MRSP150. Figures 1, 2 and 3 show dimensions for the side handling
flanges. Table 2 defines the dimensions for the side handling flanges. No obstructions may exist in the side handling
exclusion volumes which extend in the y direction (normal to the facial reference plane) as defined by x236 and
z286.
6.13 Conveyor Rails — Surfaces on the bottom of the MRSP150 used to transport the MRSP on conveyors. The
rails consist of smooth portions of the bottom periphery, parallel with each other, on two opposite sides, and
extending at least y236 from the facial reference plane (optionally the full length) on those sides. Surfaces on these
portions of the bottom periphery should be uninterrupted (ie. no notches in the surface along the bottom or the side).
No other feature of the carrier may extend below the plane defined by the surfaces of the conveyor rails. The
conveyor rail surfaces are bounded by x247, x248 and y236 as shown in Figure 10. Table 2 defines the dimensions
for the conveyor rails.
6.14 Inner and Outer Radii — All required concave features may have a radius of up to r65 to allow cleaning and
to prevent contaminant build-up. All required convex features may also have a radius of up to r66 to prevent small
contact patches with large stresses that might cause wear and particles.
NOTE 4: These limits on the radius of all required features are specified as a maximum (not a minimum) to ensure that the
required features are not rounded off too much. The lower bound on the radius is up to the carrier supplier.
NOTE 5: This radius applies to every required feature unless another radius is called out specifically. Here a required feature is
an area on the surface of the carrier specified by a dimension (or intersections of dimensions) that has a tolerance and not just a
maximum or minimum (such as the edges of the robotic handling flange).
