Polycrystalline silicon for the manufacture of semiconductors

Semiconductor manufacturers count on ultra-high-purity Hemlock Semiconductor Group polycrystalline silicon for its cleanliness and consistent quality. Manufacturing processes, such as ingot pulling, benefit from minimized dip-in time and maximized structural yield, enabling production of superior semiconductor substrates for high-tech integrated circuits.

The semiconductor manufacturing process that starts with Hemlock Semiconductor continues with our customers’ operations. From our ultra-high-purity polysilicon, our customers manufacture the ingots, wafers, fabricated wafers, and integrated circuit chips that enable computers and consumer electronics.
