Topsil has evolved around the development and manufacture of silicon. We co-pioneered the neutron doping technique (NTD process) in the 1970s, and for more than half a century, we have continued to advance and refine the properties of ultra pure silicon.

Understanding is the basis for development 

Topsil's R&D activities are based on close relations with research institutes and universities worldwide. Such partnerships enable us to draw on fundamental studies that are later transformed into in-house development and wafer prototyping, prior to volume production.
