  1. EMC for Semiconductor Manufacturing Facility, Equipment Electromagnetic Compatibility and E33 Directions Industrial Equipment EMC Regulation & SEMI E33 Mark Frankfurth, NCE, CLSO Engineering Manager Product Safety & Regulatory Compliance Cymer Inc. mfrankfurth@cymer.com Ph 858-385-6558

  2. Agenda • What is Electromagnetic Regulatory Compliance? • U.S. FCC and Similar Regulations • The New European EMC Directive • SEMI E33 Directions and Current Status • Steps Every Company Should Take to be EMC Compliant SEMICON West 2006 EMC STEP Course

  3. EMC & EM Compliance EMC = ElectroMagnetic Compatibility This is the ability of equipment to operate in its electromagnetic environment. EMC is a “performance-based” measure. EM “Compliance” is conformance to the rules of electromagnetic control regulation. This is based on Limits, Standards, Codes, Directives, and Laws. “Prescriptive” measures. These are not the same! SEMICON West 2006 EMC STEP Course

  4. Categories of EM Compliance There are a few levels of rigor in EM Compliance, these are represented by: • Verification/Self-Declaration • Industrial equipment • Certification & Authorization • Consumer electronics, radios, transmitters • Mission-critical • Medical, military, etc. SEMICON West 2006 EMC STEP Course

  5. Approaches to EM Regulation There are 2 main courses for EM regulation & compliance: • U.S. Federal Communications Commission • Code of Federal Regulations (47 CFR Part 15) • Emissions only (radiated & conducted) • European EMC Directive • Directive & EU Member Country Legislation • Emissions & Immunity (radiated & conducted) • Part of CE Mark customs enforcement SEMICON West 2006 EMC STEP Course

  6. Industrial Equipment EM Compliance The focus of this presentation is Industrial Equipment for the Semiconductor Manufacturing Industry. This means good news & bad news: • Industrial equipment EM regulation is a pretty flexible and lenient compliance environment. • Industrial equipment EM compliance is not well understood. SEMICON West 2006 EMC STEP Course

  7. EM Compliance & SEMI E33 • The goal of SEMI E33 revision is to provide EMC guidance to the suppliers and users of equipment while leveraging existing EM regulatory compliance approaches. • Compliance with the applicable legal EMC requirements for the target market will equate to conformance with SEMI E33 as currently written. SEMICON West 2006 EMC STEP Course

  8. FCC – U.S. & Canada • FCC = Federal Communications Commission • For industrial equipment, typically falling under the designation “Class A”, compliance is pretty simple: • Test to ensure emissions are under limits • Take data to develop a report • Label the product according to the FCC rules • File the data/report for later SEMICON West 2006 EMC STEP Course

  9. FCC Class A Tests & Limits • Class A testing is called “verification”. • Methods according to: • Title 47 CFR Part 15 • ANSI C63.4 standard SEMICON West 2006 EMC STEP Course

  10. The FCC Class A Label Text This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device shall not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. The product would be labeled with the following exact wording: And that is pretty much it for the FCC approach. SEMICON West 2006 EMC STEP Course

  11. Europe & International Markets The rest of the globe concerned about EMC subscribes to the European approach and standards: • EMC Directive & Member Country Laws • Current EMC Directive 89/336/EEC • New EMC Directive 2004/108 • CISPR, IEC, and EN Technical Standards We will concentrate on the “New” EMC Directive SEMICON West 2006 EMC STEP Course

  12. The New EMC Directive The newly published EMC Directive 2004/108 resulted from the SLIM and New Approach efforts to revise European Directives. Published in the Official Journal on 31 December 2004, this revision of the Directive came into force on 20 January 2005. Member states must implement it by 20 July 2007. SEMICON West 2006 EMC STEP Course

  13. 2004 2005 2006 2007 New EMC Directive Timeline The New EMC Directive was published, entered into force, and will take effect as follows: 2004/108 Legislation Published in OJ 31 Dec 2004 2004/108Entry into Force 20 Jan 2005 Member Country Implementation Deadline 20 Jan 2007 2004/108 is Mandatory 20 July 2009 2009 89/336/EEC No longer usable to place equipment on market 89/336/EEC is Repealed 2004/108 is Applied 20 July 2007 89/336/EEC In Effect Until 20 July 2007 SEMICON West 2006 EMC STEP Course

  14. More Background • The new Directive may be referred to as “2004/108”, “Edition 2”, or “2nd Edition”. • The 89/336/EEC Directive is in effect until 20 July 2007 when the old EMC Directive is repealed. • A transition period extends to 20 July 2009 before exclusive compliance to 2004/108 is required. SEMICON West 2006 EMC STEP Course

  15. More Background What is a “Directive”? • High-level goals for European Union. • Instructions for member countries to create consistent legislation. • Hint: We are required to follow the laws of the countries! • Can’t declare to the new directive yet because country legislation is not in place. (e.g. RoHS) SEMICON West 2006 EMC STEP Course

  16. Interpretations = Opinions There will be a couple of years of pontificating on the meaning of the changes. Every interpretation is just an opinion until… • Official European Commission guidance is issued or • Courts rule to set precedents Be careful who and what you believe ! (An updated interpretation “Guidance Document” is expected in late 2006 – will it be official?) SEMICON West 2006 EMC STEP Course

  17. EMC Directive Purpose • To ensure the function of the Internal European Market. • To ensure and adequate level of electromagnetic compatibility among products in the European Market. • Estimated to affect 800 Million products SEMICON West 2006 EMC STEP Course

  18. New Approach Directives • State Essential Requirements. • Are supported by harmonized standards. • The big presumption:Conformance to harmonized standards equates to meeting the essential requirements. • Conformity assessment approach is used when these boundaries are exceeded. SEMICON West 2006 EMC STEP Course

  19. Strategy As with all regulatory compliance rule changes, it is important to study the text of the rules and understand the potential impact for your products and business.Fortunately, the changes to the Directive are not large for most companies and appear to be beneficial overall. SEMICON West 2006 EMC STEP Course

  20. Outside of EMC Directive Scope • Telecom equipment under R&TTED • Aviation/Aeronautical Products • Amateur Radio Equipment – ITU • Specificity Clause (Article 4.1) • Where EMC specified in another Directive • Example = Medical Devices Directive SEMICON West 2006 EMC STEP Course

  21. Protection Requirements • Equipment shall be so designed and manufactured, having regard to the state of the art, as to ensure that: • The electromagnetic disturbance generated does not exceed the level above which radio and telecommunication equipment or other equipment cannot operate as intended. • It has a level of immunity to the electromagnetic disturbance to be expected in its intended use which allows it to operate without unacceptable degradation of its intended use. SEMICON West 2006 EMC STEP Course

  22. All in the Definitions • Equipment = apparatus or fixed installation • Apparatus = finished appliance or combination thereof made commercially available as a single functional unit, intended for the end-user… • Fixed Installation – particular combination of several types of apparatus and, where applicable, other devices, which are assembled, installed, and intended to be permanently used at a pre-defined location. SEMICON West 2006 EMC STEP Course

  23. All in the Definitions continued • Apparatus includes components or subassemblies intended for incorporation into apparatus by the end-users… • Apparatus also includesMobile Installations… • Key discrimination factor: Apparatus are made commercially available to end-users as a single functional unit. SEMICON West 2006 EMC STEP Course

  24. How Does This Apply? Large-scale, integrated equipment can potentially qualify as a “Fixed Installation” This could prove very beneficial to the shipment and installation of leading-edge technology demonstration systems where individual elements are not yet conforming to the Directive. Most equipment will be classified “Apparatus”. SEMICON West 2006 EMC STEP Course

  25. Brief List of Changes • Increased emphasis on Essential Requirements for Protection, and “good engineering practice” • Competent Bodies no longer exist in the Directive. Notified Bodies can be used. • Independent conformity assessment review of EMC compliance documentation is now purely voluntary. SEMICON West 2006 EMC STEP Course

  26. Brief List of Changes continued • Technical Construction File (TCF) has been renamed Technical Documentation that all must assemble and make available to provide evidence of conformity assessment. A 10 year document retention requirement is defined. • Non-conforming equipment may be displayed or demonstrated at exhibits, trade shows, etc. provided that: • Markings indicate equipment may not be placed on the market until conformity is achieved. • EM Disturbances from demonstrations are controlled. SEMICON West 2006 EMC STEP Course

  27. Brief List of Changes continued • Emphasis on testing different equipment configurations that could normally occur, or a known inclusive “worst-case” configuration. • Permanent custom systems are addressed as “Fixed Installations” which we will address further in this presentation. • Definitions have been updated and added to clarify terminology and interpretations. SEMICON West 2006 EMC STEP Course

  28. What is NOT There • Changes to underlying Standards • Standards are technology-driven. • Definitions of “Place on the market” or “Put into service” as triggers for required conformance. • This still must come from supplemental interpretations e.g. “Blue Book”. Guidance document planned for 2006. • Onerous cable testing provisions discussed in the development of the revision. • Involvement in Safety of products or systems • e.g. “Functional Safety” considerations SEMICON West 2006 EMC STEP Course

  29. Do Not Require: EMC Assessment Declaration of Conformity CE Mark Affixed Do Require: Compliance with Essential Requirements for Protection Attention to EMC-related installation requirements Documentation of “good engineering practices” Responsible Person holding the Technical Documentation Fixed Installations SEMICON West 2006 EMC STEP Course

  30. EMC Directive vs. WEEE Definitions The exception identified in WEEE for Large-scale stationary industrial tools appears to have little in common with the Fixed Installation definition in the New EMC Directive. Although elements of the Fixed Installation wording could be used to support a WEEE exception argument, it does not appear to be a strong case. Use caution when borrowing definitions! SEMICON West 2006 EMC STEP Course

  31. Conclusions of 2004/108 Review • Benefits are provided by New EMC Directive: • Reduced evaluation requirements under TCF Route • Notified Body oversight is voluntary • Better coverage of Fixed Installations • Trade-show provisions • Improved definitions and descriptions • Drawbacks: • Potential multiple configuration assessment requirement • Narrow scope of Fixed Installation category SEMICON West 2006 EMC STEP Course

  32. Coming EMCD Guidance Document • Contains 60+ pages to explain 14 page Directive • 5 useful Flowcharts for Classification Process • Presently undergoing refinement by Working Group • Explanations of each section: • Role of Notified Bodies • EMC-Benign Equipment • Areas Where EMCD Not Applicable • Spare Parts/Repair Activities • Technical Documentation • Scope of EMCD • Essential Requirements • Rules for Apparatus • Rules for Fixed Installations • Enforcement SEMICON West 2006 EMC STEP Course

  33. Apparatus versus Fixed Installation Bad news: Almost all products will be categorized as “apparatus”. • Definitions and interpretations of Fixed Installations very narrow, and direction is not supportive of Semiconductor Manufacturing Equipment (SME). • Fixed Installations oriented toward geographically large systems (railway systems, power-plants, etc.) or • Equipment that is built-into a physical plant, e.g. elevators, overhead cranes, communications wiring. So SME is unlikely to enjoy Fixed Installation flexibility. SEMICON West 2006 EMC STEP Course

  34. Spare Parts & Service • Much like safety guidance, if equipment is returned to the original compliant condition then no new compliance requirements are triggered. • If the equipment is changed or upgraded in a way that could change the EMC characteristics, the equipment must conform to the requirements of the New EMC Directive. • Components & subassemblies EMCD provisions apply here as well. More explanation is expected in this area. SEMICON West 2006 EMC STEP Course

  35. Conformity Assessment Options A flowchart details the potential methods for assessing EMC conformance: • Conform to Harmonized Standards • Detailed Technical EMC Assessment • Mixed EMC Assessment Much more detail expected in this area when the Guidance Document is finalized. SEMICON West 2006 EMC STEP Course

  36. EMC Conformity Assessment Flow SEMICON West 2006 EMC STEP Course

  37. SEMI E33 Directions • The SEMI E33 revision seeks to update references and overlay semiconductor industry-specific information on top of existing EMC compliance systems. • For example, conformance with the processes and requirements of the EU EMC Directive is intended to satisfy the requirements of SEMI E33. • The goal of E33 revision is improved information & awareness of EMC without increased compliance requirements for equipment. SEMICON West 2006 EMC STEP Course

  38. Steps a Company Should Take To ensure EMC and EM compliance, the following steps are recommended: • Become familiar with the New EMC Directive via self-study or available courses. • Learn pre-compliance methods and test instrument usage to improve EMC before the test lab phase. • Take advantage of EMC expertise when needed to resolve problems or interpretation issues. • Address customer EMC concerns effectively.
