ThereforeCited by: The use of neutron-irradiated silicon for the production of high voltage, high power devices has become standard.

Since this statement has been reinforced to the degree that almost all high-voltage, large-area power thyristors are presently fabricated by using neutron transmutation doped silicon as the starting by: 1.

The Silicon program utilizes the 4TH and 6TH horizontal through ports for Neutron Transmutation Doping (NTD) of single crystal silicon at the MIT Research Reactor (MITR-II). These through ports are tangent to the D2O Reflector Tank. The 4TH port can accommodate the 4-inch crystals and the 6TH port can accommodate 4, 5 and 6-inch.

Neutron transmutation doping of silicon was commercially introduced in The advent of this technique was a great step ahead in the development of high power semiconductor devices as it allows tight resistivity tolerances and excellent homogeneity of the silicon base by: N-type phosphorous doped Silicon by neutron radiation was invented by Topsil in In this NTD (neutron transmutation doping) process, Silicon atoms are transformed into phosphorous atoms.

By adjusting the level of neutron radiation, material resistivity can be altered without introducing external dopants and therefore guaranteeing material. NeutronTransmutationDoping 3 Gallium Arsenide (GaAs) Transmutation [5] Since the (n,α), (n,p) and (n,2n) reactions, as well as the fast neutron reactions, can be neglected[6], the effect of transmutation doping of GaAs is to introduce germanium (Ge) and selenium (Se) impurities.

The process of creating doped materials for semiconductors by the method of in-situ neutron transmutation doping sees increasing use in the fabrication of semiconductor devices.
