Hemlock Semiconductor Sales Worsen on Solar Oversupply

Sales at Hemlock Semiconductor Corp., the largest U.S. maker of material polysilicon used to make solar panels, continued to worsen in an oversupplied market, its largest joint-venture parent Dow Corning Corp. said today.

Hemlock is “challenged” and faces “the threat of potential duties on its products sold into China,” Midland, Michigan-based Dow Corning said in a statement today. It contributed to a 17 percent sales drop at Dow Corning in the first quarter to $1.26 billion.
