SEMI Photovoltaic (PV) Gas and Liquid Purity Taskforce Update
The Photovoltaic (PV) Gas and Liquid Chemicals Purity Taskforces of SEMI recently balloted a total of seven documents for industry input and received an excellent set of comments, allowing the Taskforce to collect these and rework them into better descriptive characteristics aimed at providing the PV industry with useful chemical guides and specifications. The chemicals concerned are Hydrofluoric Acid, Phosphoric Acid, Phosphorus Oxychloride, Oxygen, Argon, Nitrogen and Hydrogen. If you have a desire to input to this process, now is your chance while the taskforce is deliberating improvements. The task force is currently working on Silane, , Anhydrous Ammonia and Helium. Please contact Kevin Nguyen at knguyen@semi.org or Marty Burkhart at martyburkhart@hipuretech.com

Seeking Task Force Co-Leader
The PV Gas Purity Task Force is actively seeking a volunteer co-leader to help direct the efforts of a 20+ member group dedicated to defining the purity of gases used in PV manufacturing. Leaders should be able to dedicate approximately five hours per month to this volunteer assignment, which would include organizing and conducting monthly phone conferences, managing the group in reaching document consensus, bringing these documents forward to the PV industry for voting within the SEMI Standards Program, and strategic planning of future PV gas documents. Experience with gas usage for solar cell processing is necessary. Willingness to learn and abide by the SEMI Standards rules and regulations (if not already familiar with) is mandatory, but SEMI staff will help every step of the way. Prior service within a SEMI Standards (or similar) task force would be helpful, but not required, as the current Task Force leader will train the new co-leader. For more information please contact Kevin Nguyen at knguyen@semi.org

End-Users Needed
The Photovoltaic (PV) Gas and Liquid Chemicals Purity Taskforces of SEMI are actively seeking more end-users to join this important group and assist in bringing industry inputs to address the essential elements necessary for chemical materials standardization. Industry standardization has been shown to reduce overall costs of production. With liquid chemicals and gases accounting for a significant portion of PV manufacturing costs, this is a prime concern in striving to reach grid parity. To further implement this standardization, we need individuals within the PV companies who specify and use these materials. If you have a desire to give input, now is your chance while the taskforce is deliberating improvements. For more information please visit the link at http://www.pvgroup.org/NewsArchive/ctr_036232
