About Hemlock Semiconductor

At Hemlock Semiconductor (HSC), we transform people’s lives by energizing and connecting our world through silicon technology. Since 1961, HSC has been a leading global provider of hyper-pure polysilicon, and is the only polysilicon manufacturer headquartered in the United States. HSC is a chemical processing facility that plays an essential role in the semiconductor and solar industries, with the vision of becoming the preferred supplier of silicon-enabled technologies to the low-carbon, digital world.

Our polysilicon is used to make computer chips – the “brains” behind the electronic devices we rely on to make our lives easier, safer and more enjoyable. HSC is just one of six major manufacturers in the world that makes polysilicon used to create semiconductor wafers. In fact, nearly all electronic devices in the world contain HSC polysilicon.

We’re also moving the world toward a greener future by supplying the rapidly growing solar power industry. The low embodied greenhouse gas emissions in our polysilicon materials facilitates the production of ultra low-carbon solar panels. These panels allow solar project developers and owners to lower the embodied carbon of their projects by up to 50 percent.

“I loved the open, family-like culture that is present at this company. HSC is a true example that if the employees enjoy their jobs, they are more efficient and skilled at what they do; the company did a great job of combining hard work with fun, which allows for small incentives throughout the work week. My projects revolved around maintenance of the plant equipment, thus requiring a great deal of critical thinking and problem-solving on a thermodynamic engineering level. Throughout the summer, I always had someone to help answer any questions or inquiries of mine, and I engaged in a lot of insightful discussions with employees of all different roles and skill levels across the plant. Overall, this was a fantastic internship experience and a perfect way for me to gain exposure to the many facets of manufacturing.”
