Polycrystalline Silicon for Electronics and Solar Devices

Hemlock Semiconductor, a Dow Corning joint venture with two Japanese companies, the largest producer of polycrystalline silicon in the world, completed its third expansion in four years. The recent $1 billion expansion will increase their output by 90%.

Hemlock Semiconductor chose to expand in Hemlock, Michigan, because it provided the fastest time-to-market, lower capital costs, and the ability to leverage the company’s skilled employees.

• Developed an economic development package valued at $283.5 million.
• Negotiated a competitive energy rate. 
• MEDC granted $3 million to Thomas Township for public infrastructure improvements related to water delivery.
• Developed solar related legislation to support new investment.

“We received tremendous support from state and local officials, which was key to us locating this expansion here in Hemlock,” said Rick Doornbos, president and CEO of Hemlock Semiconductor, “Michigan Governor Jennifer M. Granholm and Michigan Economic Development Corporation (MEDC) CEO James C. Epolito were personally involved in supporting this expansion, and we appreciate the attention they gave us.”

As a result of Hemlock Semiconductor’s growth, Dow Corning Corporation’s Midland, Michigan, site expanded and upgraded to accommodate Hemlock’s increasing need for raw materials.
