Neutron Transmutation Doped (NTD) monocrystalline silicon is grown by irradiating undoped Float Zone silicon with neutrons.
The NTD technique is used when the application requires doping levels of high precision and uniformity.
The main market for silicon of this extremely clean and uniform quality is power semiconductor devices. Topsil has been manufacturing NTD products for over 30 years and offers the largest selection of NTD products on the market.
