The Dow Corning Corp. has unveiled plans for its newest solar energy-related manufacturing plant in Saginaw County, and has announced the start of construction on a new monosilane gas factory to make a type of gas used in thin-film solar energy cells and in liquid crystal displays. The monosilane plant will be located in Saginaw“s Thomas Township, adjacent to the Hemlock Semiconductor Group complex. Dow Corning has not reported the price of the plant nor the number of people who will be employed there. Thanks to the new factory, Dow Corning will be able to supply the building blocks for the two most common types of solar panels – those using thin-film technology with monosilane and those using wafers with polycrystalline silicon made by Hemlock Semiconductor, of which Dow Corning is majority owner. As construction of the monosilane plant starts, work is ongoing at Hemlock Semiconductor where up to USD 1 billion will be spent on a third expansion in order to supply more polycrystalline silicon to the solar industry. Hemlock is also constructing a similar factory in Clarksville, Tennessee, an initial cost of USD 1.2 billion.
