State of the art technology for pure silicon.

The leading polysilicon chunk etching system for the highest quality silicon

Use DECKER systems to eliminate bothersome particles and metallic contamination from crystalline silicon chunks in order to allow for optimal subsequent use of the chunks.

The polysilicon etching unit provides you with best silicon quality in a more efficient manner because it combines state-of-the-art wet chemical technology with maximum throughput.

One additional significant advantage of this unit is its low consumption of resources. Save a considerable amount of electricity, water and chemicals – and reduce your operating costs!

System characteristics:

  • Transportation of goods in special rotating drums
  • Innovative drying concept
  • Uncontrolled reactions after the etching process are avoided by “fast product transfer”
  • Process and design are modularly adaptable
  • Processing of silicon for photovoltaics and microelectronics
  • Ergonomic loading and unloading


  • Minimum operating costs
  • Superlative high-quality silicon
  • Innovative drying concept
  • Specially developed barrels
