Polycrystalline Silicon For Semiconductor MicroChips Super pure polycrystalline silicon (polysilicon) manufactured and sold by Hemlock
Semiconductor Corporation is an indispensable feed material for the semiconductor
industry. We sell our polysilicon in the form of chunks or rods and the material is
converted by our customers into single crystal ingots, which are sliced into wafers and
polished. These wafers are supplied to semiconductor device manufacturers who fabricate
various types of electronic devices such as microprocessors, DRAMS, ASICS, etc. HSC is the
world’s largest supplier of semiconductor polysilicon. Polycrystalline Silicon
for Photovoltaics Solar cells made from either polysilicon or single crystal silicon convert solar
energy directly into electricity. Unlike conventional power generating processes (thermal
and nuclear), electricity generated by solar cells is very environmentally friendly. HSC
is a leading supplier of this type of polysilicon. Silicon Chemicals For
Semiconductors For semiconductors and other uses very pure dichlorosilane (H2SiCl2),
trichlorosilane (HSiCl3), and silicon tetrachloride (SiCl4) are produced and sold.
The semiconductor customer often deposits thin layers of tailored single crystal silicon
on wafers to obtain desired electronic properties. These wafers are the basis
of the microchips that supply the electronics industry and make the information age
possible. |
