Asteran Inc. Russian manufacturer hexachlorodisilane (HCDS) since
Worldwide distributor of bulk HCDS (minimum order is 100 kg).
Hexachlorodisilane (HCDS) is a chemical compound
widely used is semiconductor industry for production of semiconductors, fiber optics and solar energy products. Asteran is one of the
leading providers and worldwide distributor of hexachlorodisilane located in Moscow, Russia. We manufacture low and
high purity hexachlorodisilale (HCDS) for over 20 years.
Production of semiconductors and solar cells typically is developed through atomic layer deposition (ALD) or chemical vapor deposition (CVD) processes to produce thin layer films of silicon dioxide. Asteran Inc develops carbon-free silicon precursors for use in FCVD (Flowable Chemical Vapor Deposition) reactors. Increasingly small structural sizes (< 25 nanometers) for flash memory is driving demand among the manufacturers.

Formula: Cl3Si-SiCl3 (Si2Cl6)
primary production methods:
o Low purity method
(95-98%): The usual synthetic route to
HCDS involves the reaction of chlorine on silicon alloys, but can result in low levels of metallic
contamination from the silicon alloys such as titanium.
Application is as a precursor to substituted disilanes and can
be recovery in low quantities as one byproduct of a trichlorosilane (TCS) production
within the chemical and coating sector requiring lower-purity HCDS as a precursor for substituted disilanes for
o High purity method
semiconductor grade silane disproportionation process
High purity chemicals and repetative purification processes
used in the production of ultra-pure hexachlorodidilane for semiconductor integrated circuits and solar
Please note that minimum order of HCDS from Asteran is 100 kg.
