Hemlock Brings New Polysilicon Capacity Online

The Hemlock Semiconductor Group has started operations at its new 8,500-metric ton polycrystalline silicon (polysilicon) production facility in Hemlock, Michigan. This new capacity, which has been brought online several months ahead of schedule, represents the completion of the first phase of the US $1 billion expansion the Michigan site announced in May of 2007. The polysilicon will be used by both the solar photovoltaic and traditional semiconductor industries.

The second phase of this capacity expansion will begin to come online in 2010 and, together with the first phase, will increase the total annual capacity to approximately 36,000 metric tons.

In the last five years, Hemlock Semiconductor has announced investments totaling more than $4 billion. These investments will expand Hemlock Semiconductor’s capacity by nearly 10 times while creating more than 1,500 new jobs. These jobs are in addition to the 1,000-1,800 construction contractors on site every day.

Later this year, Hemlock Semiconductor Group will also begin construction of a new polysilicon manufacturing facility in Clarksville, Tennessee, which is scheduled to be operational in 2012. Excavation has already begun at the site.
