BTU will highlight its next generation thermal processing capabilities with its distributor Rieckermann (Japan) Ltd. in booth P-D131 at PV Japan 2010 from June 30-July 2, 2010.

June 25, 2010 � BTU International (Nasdaq: BTUI), a leading supplier of advanced thermal processing equipment for the alternative energy and electronics manufacturing markets, will highlight its next generation thermal processing capabilities with its distributor Rieckermann (Japan) Ltd. in booth P-D131 at PV Japan 2010. The event is scheduled to take place June 30-July 2 in Pacifico Yokohama, Japan.

BTU will feature an array of in-line process systems that can dramatically lower cost without sacrificing cell efficiencies:
� For Silicon Photovoltaics, BTU's new TRITAN� drying and firing furnace provides faster process speeds in combination with innovative heating and gas delivery technology. The TRITAN� features TriSpeed� technology that enables aggressive temperature spikes without compromising the drying, burnout and cooling process steps.
� For phosphorus diffusion, BTU's MERIDIAN� in-line diffusion system, winner of the "Industry Choice Cell Award," combines BTU's second-generation phosphorus coating technology with quartz lined diffusion furnaces. The direct spray phosphorus coater now includes backside and topside coating and drying capabilities. An independent analysis recently showed that the cost per good wafer using in-line diffusion can be as much as $0.12 lower than a batch-processed wafer.
� For Thin Film Photovoltaics, BTU leverages its technologies and decades of experience to provide scalable, custom, in-line thermal process systems for rigid as well as flexible substrates.
