APPENDIX 1
APPLICATION NOTES
NOTICE: The material in this appendix is an official part of SEMI E100 and was approved by full letter ballot
procedures on September 3 and December 15, 1999 by the North American Regional Standards Committee, but the
recommendations in this appendix are optional and are not required to conform to this standard.
A1-1 Edge contact only with the photomask is
preferred when handling, transporting, or storing.
A1-2 Skewness, warp, rock, and stiffness are implicitly
defined in the geometric tolerances.
A1-3 A 6 inch reticle with a 140 mm wide pellicle can
be accommodated in the RSP, but may require
automation which approaches from above the reticle.
A1-4 Features on the RSP which enable stacking may
be required by end users. It is preferred that these
features allowing stacking in only one orientation.
A1-5 Features on the RSP which provide visual
orientation of the RSP top and RSP door may be
required by end users.
A1-6 In order to permit end-effectors, which can
handle both 230 mm and 6 inch reticles, it is recom-
mended to include the 230 mm end-effector exclusion
volumes in RSPs configured for 6 inch reticles.

ADDITIONAL INFORMATION
NOTICE: The material in this appendix is an official part of SEMI E100 and was approved by full letter ballot
procedures on September 3, 1999 by the North American Regional Standards Committee.
A2-1 Features on the RSP which enable stacking may be standardized in the future pending learning from first
design approaches and standardization of reticle ID location.

GUIDE FOR EFEM FUNCTIONAL STRUCTURE MODEL
This guide was technically approved by the Global Physical Interfaces and Carriers Committee and is the
direct responsibility of the North American Physical Interfaces and Carriers Committee. Current edition
approved by the North American Regional Standards Committee on August 16, 2004. Initially available at
www.semi.org September 2004, to be published November. Originally published February 2000; previously
published October 2000.
1 Purpose
1.1 Productivity improvement is the task with the
highest priority in semiconductor factories of the 300
mm generation, and computer-integrated manufact-
uring or factory automation (CIM/FA) technologies
become more and more important to accomplish it. The
standardization of these technologies is also necessary
to provide the CIM/FA infrastructure in a short period
of time at a low cost. Since the standards will have to
cover a wide range of production equipment, communi-
cation hardware, and software tools, it is very important
that the standards have a high degree of compatibility.
In order to improve the compatibility, this guide
provides a functional structure model of an Equipment
Front End Module (EFEM) that handles carriers and
substrates at the interface between the factory material
handling system and the process equipment.
1.2 The major purposes of this guide are as follows:
1) provide a common understanding of functions of
EFEM (Equipment Front End Module) and associated
interfaces between functional elements (components
with particular function roles),
2) provide a common understanding of the hierarchical
structure of functions and their interfaces in an EFEM,
3) provide a common understanding of possible units
used for maintenance, adjustment, and control, and
4) provide a map between EFEM functional elements
and existing standards.
2 Scope
2.1 Model Structure and Functions
2.1.1 This document recognizes EFEM as a component
of semiconductor manufacturing equipment. It creates
an EFEM functional structure model to clearly describe
EFEM, its functional elements, and the functions of
each functional element. The functional structure model
includes the following:
1) definition of functional elements that constitute
EFEM,
2) definition of functions of functional elements, and
3) hierarchical description of functional elements.
2.1.2 For clarity, Fixed Buffer Type EFEM and
Internal Buffer Type EFEM (see Terminology) are
represented as independent functional structure models
in this document.
2.2 Preconditions for Modeling
2.2.1 The models are created under the following
conditions:
1) Modeling should be restricted to SEMI E15.1,
Option 1, Options 2 and 3, and Option 3 types. (See
SEMI E15.1, Figure 2 (Load Port Options)).
2) The model supports handling of open cassette (OC),
and Front Opening Unified Pod (FOUP) (see
Terminology).
3) The model is created for the maximum structure
including options.
4) Functional elements that have interfaces with EFEM
are also included in the model.
NOTE 1: Functional elements that don’t belong to EFEM, but
are important in defining interfaces among the functional
elements, are represented in this model to clarify their
functional positions and attributes in the entire equipment.
NOTICE: This standard does not purport to address
safety issues, if any, associated with its use. It is the
responsibility of the users of this standard to establish
appropriate safety and health practices and determine
the applicability of regulatory or other limitations prior
to use.
