HSC polysilicon and
A Collaboration for Innovation.

The invention of the integrated circuit in the late 1950s marked the beginning of the Information Age. Founded a few short years later in 1961, Hemlock Semiconductor is the longest operating manufacturer of polycrystalline silicon in the world.

HSC is one of six manufacturers in the world that makes polysilicon used to create semiconductor wafers. Polysilicon from HSC is the building block for all electronic devices, including cell phones, computers, tablets, televisions and more.

Our hyper-pure polysilicon becomes fabricated wafers and integrated circuit chips used by leading semiconductor manufacturers. As the nation’s leading supplier of polysilicon, HSC enables innovation and fuels economic, technological and societal progress.

Future demand for digitization and personal electronics means that HSC will continue to play a key role in the industry for years to come.
