MATERIA PCE & OCC

With the MATERIA platforms, SINGULUS launches its new product for raw material preparation. The MATERIA is a batch system for chemical etching, cleaning, and drying of mono & multi silicon chunks and Ingot Off Cuts.The system is adapted to the high purity demand in silicon production. Simultaneously, lowest possible total cost of ownership has been a key driver in the development of this machine. The MATERIA is a fully automated system for high throughput industrial production. It relies strongly on the SILEX product line for cell fabrication which can look back on a worldwide installed base of over 100 machines.
