Hemlock Semiconductor Group – delivering the highest-quality polysilicon
for semiconductor and solar wafer manufacturing
Semiconductor and solar ingot/wafer manufacturers rely on Hemlock
Semiconductor Group as a consistent, reliable source of high-purity polycrystalline silicon and chlorosilanes.
Hemlock Semiconductor has been an industry leader for more than 50 years,
helping keep you at the forefront of your industry.
For semiconductor wafer manufacturers
Rigorous quality standards and analytical
methods result in the consistent surface and bulk purity and performance of
the products you buy. You can count on the high purity and repeatable
performance of Hemlock Semiconductor's products to minimize dip-in time, and
maximize structure yield in your operation.
For solar wafer manufacturers
Our solar grade polycrystalline silicon is manufactured with semiconductor quality
standards. Our broad product portfolio of cut rods, chunks, chips, and fines
allows maximum crucible loading (density) suitable for both multi- and
mono-crystalline wafer production.
You can count on us as a production-proven source to deliver high-purity
silicon on a consistent and reliable basis.
Unlike some polycrystalline silicon suppliers, we focus on the raw materials
you need, so you can focus on your products.
