Hemlock Goes Home for More Polysilicon
Polysilicon manufacturer Hemlock Semiconductor will spend $1 billion over the next four years to expand its main plant in Hemlock, Mich. Set for completion by 2012, the move will add 17,000 metric tons of annual capacity for polysilicon suitable for both the semiconductor and solar markets. Hemlock is just completing a $500 million upgrade of its facilities that is adding 9,000 metric tons of capacity. The company said last year that it was seeking a new location to expand further, but it settled on the Hemlock site because the work could be completed there sooner and at a lower cost. Hemlock notes that it's under pressure to ramp up capacity because "the solar energy market is growing at a tremendous pace." Dow Corning, owner of two-thirds of Hemlock, will expand its own facilities in Midland, Mich., to supply raw material to Hemlock.
