About us

Welcome to the website of Silicon Products Group

The Silicon Products Group is a German medium-sized, privately owned and owner-managed group of companies specialized in silicon production and other related products from chlorosilanes. Furthermore, the group offers different engineering services for other complex production processes in the chemical industry.

The group engineered and operated a mid-scale silicon production plant in Germany since 2009 by using the established Siemens process. The plant was designed for production of solar grade silicon only. Meanwhile extended processes have been implemented to achieve high-quality polysilicon . That includes also feedstock for the Float Zone (FZ) process and semiconductor applications.

Our engineering and production experience as well as our research and development skills have led to an excellent knowledge of chemical and high temperature related equipment not only in the silicon and chlorosilane industry. Design experience, know-how and solid high international standards in quality and service enable us to offer tailor-made solutions and optimized production equipment to our customers by German engineering.

Silicon Products Technologies GmbH (SPT)

SPT was founded as part of the company Silicon Products Group. This company, sited in the same area, has the goal of offering to other chemical companies our many years experience and know-how on the process of chemical products production. The field of activity of SPT is mainly focused on:

  • Design and commissioning of chemical production plants.
  • Technology improvement and plant optimization.
  • Development of equipment and its testing e. g. CVD-reactors, converters, slim rod pulling units, welding devices.
  • Quality control and safety.
  • Operation and staff training.

Silicon Products Bitterfeld GmbH & Co.KG (SPB)

SPB operated a mid-scale silicon production plant close to the city of Leipzig (Germany).
SPB is active in the fields as follows:

  • Production of polysilicon for photovoltaic and semi-conductor purposes and related products (slim rods, chlorosilanes e.g. trichlorosilane, hexachlorodisilane).
  • Research and development on e.g. Siemens process, hydrogenation, slim rods with the focus on cost reduction and quality improvement.
  • Research and development on technology for standard thickness kerfless wafers using epitaxy process.

SPB is convinced that our production technology offers excellent technological standards so that an economically viable production of silicon and other related products are assured and highly competitive.
