1 Background Statement for SEMI Draft Document 5388 Revision of SEMI PV with Title Change To: PRACTICE FOR ASSIGNING IDENTIFICATION NUMBERS TO PV Si BRICK, WAFER AND SOLAR CELL MANUFACTURERS Notice: This background statement is not part of the balloted item. It is provided solely to assist the recipient in reaching an informed decision based on the rationale of the activity that preceded the creation of this Document. Notice: Recipients of this Document are invited to submit, with their comments, notification of any relevant patented technology or copyrighted items of which they are aware and to provide supporting documentation. In this context, patented technology is defined as technology for which a patent has issued or has been applied for. In the latter case, only publicly available information on the contents of the patent application is to be provided. The length of the three-digit code number identifying the manufacturer of the brick/wafer in the brick slice code in PV32 has to be limited to 7250 µm due to technical reasons (field of view of readers) in order to allow to mark 1 Million bricks per year. This means that not all possible three-digit numbers can be used for identifying high volume manufacturers of bricks/wafers. This revision to PV34 will implement the length limit and list the numbers that have to be reserved and may be used for future, special purposes and makes PV34 compatible with AUX25. The corresponding SNARF was approved by the PV Automation Committee in its meeting in Berlin on March 27, The draft document was approved for yellow letter ballot in cycle 5 for 2012 by the PV Automation Committee in its meeting in Berlin on March 27, 2012 to be adjudicated in Dresden in October Review and Adjudication Information Task Force Review Committee Adjudication Group: PV Wafer Traceability TF PV Automation Committee Date: Monday, October 8, 2012 Monday, October 8, 2012 Time & Timezone: 13:00 to 15:00 CET 15:00 to 17:00 CET Location: Messe Dresden Messe Dresden City, State/Country: Dresden, Germany Dresden, Germany Leader(s): Peter Wagner István Győry (Innovation Engineering & Services GmbH) Eberhard Teichmann (Peer Group) Martin Zennig (Jonas & Redmann) Tino Korner (Q-Cells) Standards Staff: Yann Guillou yguillou@semi.org Yann Guillou yguillou@semi.org This meeting s details are subject to change, and additional review sessions may be scheduled if necessary.

2 SEMI Draft Document 5388 Revision to SEMI PV with Title Change To: PRACTICE FOR ASSIGNING IDENTIFICATION NUMBERS TO PV Si BRICK, WAFER AND SOLAR CELL MANUFACTURERS 1 Purpose 1.1 Process and quality control for PV Si wafer and solar cell manufacturing requires marking the wafers or solar cells with code that uniquely identifies their origin and date of manufacturing. 1.2 Future legal requirements also may request such a code. 1.3 A unique identification of manufacturer and its location has to be part of this code. 1.4 This practice intends to establish a system of identification numbers for the PV industry, similarly to the one that is well established in the semiconductor industry (SEMI AUX001). 2 Scope 2.1 This practice covers the assignment of identification numbers for crystalline PV Si brick and wafers as well as Si solar cell manufacturers and their locations. 2.2 It does not cover module manufacturers, thin film solar cell manufacturers and PV concentrator manufacturers. NOTICE: SEMI Standards and Safety Guidelines do not purport to address all safety issues associated with their use. It is the responsibility of the users of the Documents to establish appropriate safety and health practices, and determine the applicability of regulatory or other limitations prior to use. 3 Referenced Standards and Document 3.1 SEMI Auxiliary Documents AUX001 List of Wafer Supplier Identification Codes AUX025 List of Identification Codes of Suppliers of Si Bricks, Si Wafers and Photovoltaic c-si Solar Cells for Use in the PV Industry NOTICE: Unless otherwise indicated, all documents cited shall be the latest published versions. 4 Summary of Practice 4.1 An application for an identification number is submitted by a company or research institute to SEMI Standards. 4.2 SEMI Standards assigns a unique identification number to the applying company or institute. 4.3 SEMI Standards publishes the lists for wafer manufacturers and solar cell manufacturers as an auxiliary document (AUX025) and updates it accordingly. 5 Procedure 5.1 Applicant: Fill application form (Table 1). NOTE 1: This form will be kept in SEMI Standards records but will not be published. 5.2 Applicant: Submit application to SEMI Standards with an accompanying letter (see Related Information 1) For brick/wafer manufacturers and solar cell manufacturers: SEMI Standards: Issue an identification number from the number space 001 to 999 for silicon brick and wafer manufacturers and from the number space to 9999 for solar cell manufacturers according to the arrival date of the application at SEMI Standards and their alphabetical order according to the company name SEMI Standards: Start these lists with 001 and 10010, respectively SEMI Standards: Issue the next available higher number for new entries.
