Silicon chemical products from Hemlock Semiconductor are critical in
specialized semiconductor manufacturing processes.
Semiconductor-grade chemicals meet the specialized needs of semiconductor
Extremely high-purity, semiconductor-grade dichlorosilane (H2SiCl2) and
trichlorosilane (HSiCl3) are produced in the polycrystalline silicon
manufacturing process. These materials are captured and separated, with a large
percentage recycled within
Hemlock Semiconductor Group manufacturing processes.
Additional quantities are sold to manufacturers for use in chemical vapor
deposition (CVD) of thin films in electronics applications.
