Does SEMI have standards for Photovoltaic (PV) applications?
Does SEMI have standards for use in the High Brightness LED industry?
How about SEMI Standards for the Three-dimensional Stacked Integrated Circuits (3DS-IC) industry?
Does SEMI have accreditation or certification for S2?
SEMI does not perform accreditation or provide certification for SEMI S2. We do not maintain listings of accredited third party evaluators. The third-party evaluators are consultants who perform safety evaluation for semiconductor manufacturing equipment. These consultants are “self-declared” evaluators who are considered professionals and experts in the fields of safety, loss control, engineering, industrial hygiene, fire prevention, product safety, etc.
For information on listings or services of third party evaluators, the Internet provides links to the companies who conduct S2 evaluation. Please type “SEMI S2 Certification” or you may visit our Web site and search under Membership Directory.
Does SEMI have standards for ergonomics?
SEMI S8 - Safety Guidelines for Ergonomics Engineering of Semiconductor Manufacturing Equipment
These guidelines provide ergonomics design principles and considerations for semiconductor manufacturing equipment. The purpose of these guidelines is to promote compatibility between the user and the equipment in the manufacturing environment.
Is there a SEMI Standards for CE Marking that describes CE compliance?
SEMI Standards do not cover CE Marking. The CE Marking was mandated under the European Union Directives.
European Union Directives
On January 1, 1995 a set of European Union (EU) Directives came into effect requiring the "CE" mark on a wide range of products entering European Union member states. The term "European Union" refers to the European Community, EC, or the Common Market. The change to European Union is a result of the Maastricht Treaty.
The intent of the EU directives is to eliminate non-tariff barriers to trade and to assure that products flowing throughout the EU comply with general safety and environmental norms. An EU Directive sets a norm. Member states are under legal obligation to implement the Directives.
SEMI has been following European Directives that impact SEMI Members and Business Affiliates. The primary European Directives requiring CE marking that we have been following are:
Three Major Directives:
- Machinery Directive
- Electromagnetic Compatibility Directive
- Low Voltage Directive
For more information on CE Marking, visit the SEMI Advocacy webpage for CE Marking.
Does SEMI maintain listings of approved NRTL to carry our third party assessment for S2?
NRTL stands for Nationally Recognized Testing Laboratory. NRTLs are third-party organizations recognized by OSHA as having the capability to provide product safety testing and certification services to the manufacturers of a wide range of products for use in the American workplace.
The testing and certifications are based on product safety standards developed by U.S.-based standards developing organizations.
SEMI does not maintain listings of approved NRTL laboratory.
For more information, please visit OSHA website.
Does SEMI have a list of companies that provide SEMI F47 conformance testing services?
SEMI does not maintain list of companies that provide testing services in conformance with SEMI F47. We recommend that you search the Internet and look for laboratories that do “SEMI F47 Testing or conformance”. These are self-declared consultants who perform the testing and are not in anyway connected with us or accredited by SEMI.
Which SEMI Standards define specification for polished single crystal silicon wafer or polycrystalline silicon?
SEMI M1 - Specifications for Polished Single Crystal Silicon Wafers
This specification provides the essential dimensional and certain other common characteristics of silicon wafers, including polished wafers as well as substrates for epitaxial and certain other kinds of silicon wafers.
These specifications cover ordering information and certain requirements for high-purity, single crystal polished silicon wafers used in semiconductor device and integrated circuit manufacturing or as substrates (or starting wafers) for other kinds of wafers, including epitaxial, annealed, and SOI wafers.

It defines six basic equipment states into which all equipment conditions and periods of time must fall.
Does SEMI have standards for cleanrooms?
Other than SEMI F21 - Classification Of Airborne Molecular Contaminant Levels In Clean Environments, SEMI does not possess any specifications for cleanrooms.
The two most often specifications cited in SEMI Standards for cleanroom cleanliness are:
ISO 14644 - Cleanrooms and Associated Controlled Environments Part 1: Classification of Air Cleanliness
Federal Standard 209E - Clean Room and Work Station Requirements, Controlled Environments
Federal Standard 209E - Clean Room and Work Station Requirements, Controlled Environments is also still cited in some standards. However, please note that the U.S. General Services Administration released a notice of cancellation for this document in November 2001. In that notice, ISO 14644 Part 1 (Classification of air cleanliness) and Part 2 (Specifications for testing and monitoring to prove continued compliance with ISO 14644-1) were specifically mentioned as superseding FED-STD-209E. The full notice of cancellation is available at http://www.iest.org/
For further information regarding cleanrooms and applicable standards, we recommend contacting one or more of the following:
ISO (International Standards Organization) at http://www.iso.ch
IEC (International Electrotechnical Commission) at http://www.iec.ch

Is there a SEMI Standards carrier for 200 mm wafers?
In 1994, SEMI E1.7, Specification for a 200 mm Plastic and Metal Wafer Carriers was published as a Proposed Standard. Due to the nature of a proposed standard, this standard was removed from publication in 1996, two years after its initial publication.
The standards work on an official 200 mm carrier stalled and eventually was discontinued, due to a lack of consensus on the few last details of the carrier, the number of product currently on the market at the time that would be "obsoleted" by the standard, and a shift in effort towards 300mm carriers.
In 2009, SEMI E1 (Specification for Open Plastic and Metal Wafer Carriers) was rewritten to include dimensions for all of the carriers standardized from 3 inch to 150 mm. These dimensions were previously published as SEMI E1.1 through SEMI E1.5. There has been no change in these dimensions.
SEMI E1 also includes, as Related Information (not as a Specification), dimensions from the SEMI E1.7 Proposed Standard. This information is added for historical interest. It is not an official part of SEMI E1.
Can SEMI provide an electronic version of the "SEMI-OCR" Character Set?
AUX015 SEMI Optical Character Reading (OCR) Character Outlines, free of charge, provides “single-density” mode, using a dot matrix of 5 dots horizontal and 9 dots vertical and “double-density” mode, using a dot matrix of 10 dots horizontal and 18 dots vertical.
This is the only character set provided by SEMI OCR. One may use this font style as wished. Unfortunately, many standards users have a perception that SEMI has a separate Optical Character Recognition font styles.

How are SEMI Process Chemicals Standards designated?
Chemical Standards (Specifications) are designated by “grade” and Guidelines by “tiers”
0.8 to 1.2 µm
0.2 to 0.8 µm
0.09 to 0.2 µm
< 0.09 µm
Purity levels in Specifications can be validated by commonly accepted analytical quality control methods. Guidelines reflect future chemical-purity needs for which a complete set of test methods is not generally available when the guideline is being developed.
There are also some Guidelines designated "VLSI grade." These Guidelines also describe a chemical purity level appropriate to produce semiconductor devices with geometries between 0.8 and 1.2 µm.
Where can I find the ASTM F1.06 documents that were transferred to SEMI?
