silane production - GT Advanced Technologies

POLYSILICON
SILANE PRODUCTION
Supplying Basic Engineering Packages for Ultra-Pure Silane Production
The production technology package offered by GT Advanced Technologies to produce
silane, results in ultra-pure gas that can be sold on the merchant market or used for the
production of electronics-grade polysilicon or consumed in thin-film applications.
GT personnel have direct design, construction, commissioning, startup, analytical
and operational experience at several silane plants, and the company has supplied
technology to numerous additional clients. Continuously at the forefront, GT
supplied the silane production equipment and technology to SMP Ltd. in Korea,
which is a joint venture between MEMC Singapore (a subsidiary of MEMC Electronic
Materials Inc.) and Samsung Fine Chemicals.
The high volume hydrochlorination and silane production/purification package is
capable of producing approximately 12,500 MTA of silane from a single hydrochlorination fluid bed reactor (FBR) and a single silane production/purification line.
Cost of ownership is lowered by several million dollars because of lower capital costs
when compared to facilities utilizing a dual FBR and dual silane production/
purification approach. The capital expenditure is reduced by minimizing equipment and
simplifying the construction management complexity.

Silane and Chlorosilane Analytical Processes
GT Advanced Technologies is
In the hydrochlorination and silane production/purification processes, it is of the
utmost importance to remove impurities before the silane is used for polysilicon
production or sold to the merchant market. However, in order to accomplish
this, impurities must first be quantified as well as identified precisely where they
concentrate in the process. The Silane and Chlorosilane Analytical technology
package (sold separately) from GT allows accurate measurement of trace impurities
in silane and chlorosilanes to meet stringent quality requirements for the silane
merchant market or electronics-grade polysilicon producers.
dedicated to delivering the
highest levels of satisfaction
in the implementation of our
processes and equipment.
We respond to the needs of
