Teamwork Efficiency Order Confidence Fine Silicon Co.,Ltd. Polysilicon Production The Fine Silicon Advantage Sanjeev Lahoti Virasa Technologies, Inc. Polysilicon production There are three major production processes in use in the industry today Tricholosilane (TCS) – Siemens type reactors Monosilane – Siemens type reactors Monosilane – FBR There are two different ways to manufacture monosilane TCS redistribution to monosilane Silicon tetrafluoride to monosilane Process Selection Criteria High Quality Polysilicon Process should be semiconductor quality capable Low Environmental Impact No hazardous waste generation Low electricity usage Competitive Cost World class production cost Typical TCS – Siemens TCS – Siemens Most available technology in the market High power usage 130- 200 kWh/kg Closed loop process is difficult to operate Pollution issues especially if closed loop process is not operating at full utilization TCS purification is difficult resulting in poor quality polysilicon High water and other resource usage Fine Silicon Process Process Advantages Low energy usage 60 kWh/kg polysilicon No complicated recycle loop or environmental issues Only process that starts with commonly available quartz sand rather than metallurgical silicon Specialized reactor design Capable of producing semiconductor grade polysilicon Proprietary low-cost technology differentiated from other new polysilicon producers Other Fine Silicon Advantages The Fine Silicon technical team has over 100 engineers and has been in place for over 12 years Intense focus on process and safety training Focused on producing high quality polysilicon to enable the production of higher efficiency wafers and cells Technology Partner Virasa Technologies, is the technology partner for Fine Silicon Provides complete process support for the design, construction and start-up of polysilicon plants. All the principals have direct hands-on polysilicon manufacturing and design experience Specialize in m
