NTD silicon (neutron-irradiated silicon) excels in the uniformity of resistivity in the plane and is used as a power thyristor (silicon-controlled rectifier), widely utilized in semiconductor power devices across various industries from general industry to home appliances. Currently, FZ silicon is widely used not only in existing ICs such as memory and DSPs due to its low level of contaminants but also in the fields of MEMS and optoelectronic sensors. For more details, please contact us.

Gas-doped FZ silicon is FZ silicon that has been doped with impurities by pulling a single crystal in a dopant gas. Our company can provide high-quality, high-purity FZ silicon. Currently, due to its low level of contaminants, FZ silicon is widely used not only in existing memory and DSP ICs but also in the fields of MEMS and optoelectronic sensors. Please contact us for more details. ★Prime Grade FZ ingot (available for immediate delivery) A manufacturer's Certificate of Compliance (CofC) will be provided upon delivery.
