As part of its strategy to supply a complete materials offering to the PV industry, Dow Corning has brought online a new 4,000MT per annum monosilane gas facility, adjacent to Hemlock Semiconductor’s polysilicon manufacturing plant in Hemlock, Michigan.
“Technology and innovation can only grow as fast as manufacturers are supplied raw materials,” said Eric Peeters, vice president, Dow Corning Solar Solutions. “The solar energy market depends on a reliable supply of high-purity monosilane gas as one of those key raw materials. There are only a few major manufacturers of monosilane, and most of them use much of their supply for their own downstream processing. So up until now, monosilane hasn’t always been available when customers needed it.”
The company claimed that the purity levels of the monosilane produced at the plant have consistently matched that of the leading supplier [REC], and are above industry specifications.
