Hemlock Semiconductor Corporation

Hemlock Semiconductor Corporation is the largest producer of polysilicon in the United States. It is a subsidiary of Dow Corning founded in 1961, and named after Hemlock, Michigan, the location of its factory. Its current facilities produce some 36,000 tons of polysilicon, ranking it among the top five producers worldwide.[1]

Tennessee facility

The company expanded with the Japanese joint venture partners Shin-Etsu Chemical and Mitsubishi Materials, for a new $1.2 billion plant opening near Clarksville, Tennessee. Though it officially opened in 2012, chemicals were never inventoried and no product was made. The plant was under negotiations in 2011 for a further $3 billion expansion, to keep pace with manufacturing competition from China.[2]

In December 2014, Hemlock Semiconductor Corporation announced the permanent closure of the $1.2 billion Tennessee plant, due to adverse conditions from industry oversupply and ongoing challenges from global trade disputes. Many of the approximately fifty employees in Tennessee were offered employment positions in Michigan at the Hemlock Semiconductor or Dow Corning facilities, and the rest received severance packages.[3]

In December 2015, Google announced that they will buy the facility, and invest more than $600 million to turn it into their 15th datacenter.[4]
