Hemlock Semiconductor is a leading provider of polycrystalline silicon and other silicon-based products used in the manufacturing of semiconductor devices, and solar cells and modules. Hemlock Semiconductor began its operations in 1961.
An ultra-pure version of polysilicon is the base material for silicon wafers
used in electronic devices. Nearly one in three electronic devices in the
world contain polysilicon from Hemlock Semiconductor. Polysilicon is the
cornerstone material used to produce solar cells that convert energy from
the sun into electrical current. Polysilicon production is the first step in the solar supply chain. A series of global solar manufacturing companies will convert the polysilicon into thin wafers, which are used for solar cells. Ultimately, the solar cells are built into solar panels and arrays that provide electrical power for residential, commercial, municipal and utility-scale applications.
