MEMC Electronic Materials - Business Segments

Business Segments

Since the acquisition of SunEdison MEMC has had three reporting segments.

• Semiconductor Wafers delivers wafers to the electronics industry. Products of MEMC include 300 mm wafers, production capacities allow for 2 million wafers per month. Apart from plants in Asia (Utsunomiya, Japan; Chonan (South Korea); (Taisil), Taiwan ; Kuala Lumpur und Ipoh (both Malaysia) MEMC operates a production facility in Novara (Italy). Production plants in the United States (St. Peters, (Missouri), Sherman (Texas)) are scheduled to be closed and capacities to be moved to Asia. MEMC produces polished and epitaxial wafers, High Resistivity Wafers and SOI Wafers. Main competition in this segment comes from SUMCO, ShinEtsu, Siltronic and Siltron. The market share of MEMC is roughly 12 per cent.

• Solar Materials: MEMC produces Polysilicon in purities usable in the solar and semiconductor industry in Pasadena, (Texas)) and Merano, (Italy). Production capacities equal 10,000 tons per annum, an expansion to 12,500 by the end of 2011 was announced. The material is mainly used for their own following production steps, sales to the spot market occurred between 2006 and 2009. Apart from opportunistic sales of silanes the segment sells mainly solar wafers. As their own productions capacities of 600 MW were not sufficient, MEMC also had tolling partners to produce these wafers.

• SunEdison offers customers access to solar power without financing the individual projects generating the power. SunEdison collects capital from investors and uses it to construct photovoltaic plants (installing MEMC Solar Wafers in some cases). The plants are operated by SunEdison after construction. Investors receive a cash flow from sold solar power, including subsidies from governmental organizations. The solar power is sold to commercial, government, and utility customers.
