Reducing the switching time of semiconductor devices by neutron irradiation

Description

The switching time of certain semiconductor devices is decreased while maintaining other electrical characteristics of the devices by irradiating them with a neutron radiation source of greater than 1.0 MeV. To a dosage between 1 X 1011 and 1 X 1015 neutrons per square centimeter. The irradiation is preferably to a dosage between 1 X 101 and 1 X 1014 neutrons per square centimeter and preferably has substantial energy greater than 14 mev. The devices are also annealed during and/or subsequent to the irradiation at a temperature higher than the highest specified temperature and preferably at least 500C. Higher than the highest specified temperature
