Etching & Drying

ALZTEC’s highly sophisticated etching and drying system is designed to produce ultra-pure, shiny and excellent dust-repellent polysilicon chunks.

The use of PVDF, ECTFE, and Halar® coatings ensures outstanding chemical resistance and maximum purity. An ISO Class 4 cleanroom environment supports exceptional cleanliness standards and consistent product quality.

Driven by continuous research and development, ALZTEC’s process technology is designed to meet future purity requirements and is prepared for contamination levels in the sub-pptw range.
