Hemlock Semiconductor Names Mark Bassett, Ph. D., Chairman and CEO

Mark Bassett, Ph. D. has been named chairman and CEO of Hemlock Semiconductor, effective June 1. Bassett, who currently serves as global vice president of The Dow Chemical Company's Polyurethanes business, replaces Denise Beachy, who has been named commercial director for Europe, Middle East, Africa and India for Dow's Elastomers, and Electrical and Telecommunications business.

As Hemlock Semiconductor's chairman and CEO, Bassett will be responsible for driving business and technology initiatives that grow the company while building upon its 55 years of pioneering leadership in polysilicon technology.

"Mark's strong business acumen combined with his deep chemical engineering expertise make him a great fit to lead Hemlock Semiconductor into a new era," said Howard Ungerleider, vice chairman and chief financial officer of Dow, and chairman of Dow Corning. "Mark and his team are dedicated to further developing Hemlock Semiconductor's legacy as one of the world's premier providers of high-purity polysilicon to the electronics and solar industries."

"The opportunity to lead one of the pioneers of the polysilicon industry is an exciting one," said Bassett. "Hemlock Semiconductor's products are key enablers of many of the electronic and solar technologies so important to our world today. I'm looking forward to working with the talented team at Hemlock Semiconductor to enhance our capability of providing high-quality polysilicon to our customers as the need for our products continues to expand."

Bassett was appointed to his previous role as global vice president of Dow's Polyurethanes business in 2012, and was responsible for global business strategy and financial performance for a business which produces polyurethane products such as foams for furniture, automobile, industrial and energy efficiency applications. Prior to this role, he served as global business director for Dow Oxygenated Solvents which manufactured industrial coatings and cleaners, inks, and other chemical intermediates.

Bassett's diverse career started at Union Carbide Corporation in 1989 in the company's Reaction Engineering Skill Center. He then transferred to the Company's Research and Development group, supporting the acetone derivatives business, and later added support for the glycol ethers business. In 1999, he assumed the role of finance director in the same business. He then served as marketing manager for acetic and propionic esters, through a series of promotions and roles of increasing scope and responsibility, assumed the role of commercial leader for Coatings. Later, he was named a global business director in Dow's Acrylic Monomers business in 2007.

On June 1, Dow and Corning Inc. announced the successful completion of the transaction to restructure the ownership of Dow Corning, which formerly was majority owner of Hemlock Semiconductor. Dow and Corning will maintain their equal proportional equity interests in Hemlock Semiconductor, and Shin-Etsu Handotai will maintain its minority share.
