ABOUT US

REC Silicon - An Industry Leader

Whether supplied as a gas, gas derivatives, or used internally to manufacture ultra-pure polysilicon, our Signature Silane® is increasingly demanded for leading-edge power devices, big data, nano-electronics, communication devices, and renewable energy industries.

Signature Silane® is also what sets us apart.

ABOUT US

OUR PROCESS & TECHNOLOGY

SIGNATURE SILANE®

At the core of REC Silicon's technology is our molecule, SiH4, and the safe, sustainable best practices to produce it.

Siemens Processes

›Based on the decomposition of Signature Silane® (SiH4):
Heating until the ultra-pure elemental silicon and hydrogen are separated.
-Silicon seed rods are heated, and the elemental silicon is deposited.
-Hydrogen is removed and recycled.

Resulting high-purity product is ideal for Float Zone (FZ) and Czochralski (CZ) polysilicon applications.

Fluidized Bed Reactor (FBR) Processes

›FBR uses seed granules continuously fed into a chamber with heated silane.
› Circulation of gas causes the seed granules to flow like a liquid as silane breaks down and deposits silicon layers on the granules.
-Hydrogen is removed and recycled.
›Over time the granules grow larger, heavier, and finish out the bottom.
›Energy consumption is reduced 80-90% per comparative Siemens-silicon while producing more silicon per cubic meter of reactor space.

Smallest carbon footprint in the industry being fueled by hydroelectric power at the Moses Lake facility.

ELECTRONIC GRADE POLYSILICON

Our electronic grade ISO 9001-2015 certified polysilicon businesses provide a variety of form factors for uses in high-tech energy and electronics industries.

›Float Zone (FZ)

-FZ-based devices are used in motor control and power conversion processes for hybrid and electric vehicles, wind energy, and high voltage transmission, 5G communications, high-speed trains, IoT (internet of things), and big data.

› Czochralski (CZ)

-This form of electronic grade polysilicon is principally used in manufacturing of 12' semiconductor wafers used in memory processors, optics, and micro electromechanical systems (MEMS).

GRANULAR SOLAR GRADE POLYSILICON

The most efficient technology to make polysilicon

›Our granular polysilicon, NextSi®, when blended with solar grade chunk polysilicon:
-Enhances efficiency of the ingot manufacturing process by increasing the weight and yield of the ingot
-Reduces process cycle times
-Ready-to-use

NextSi® is ideal for multicrystalline and monocrystalline solar ingot and wafer production in the manufacturing of solar modules.
