The proton soft error rates calculation technique of commercial memory circuits based on heavy ions data is offered. Soft error rates by means of Monte Carlo simulation of secondary particles LET-spectra in the circuit’s sensitive slab are calculated. The calculation procedure by the direct comparison with on-board data is verified.

Keywords: single event effects, soft error rate, cross-section, protons, secondary particles, Monte-Carlo technique.

A calculation-experimental method of prediction the level of free-failure functioning of bipolar integrated circuits in the conditions of pulse gamma-neutron radiation influence is considered. The level of free-failure functioning is estimated by the critical parameter UOL – low-level output voltage, which degradation defines radiation resistance of bipolar digital integrated circuits as a whole. For estimation of production reserve on UOL and estimation of its degradations speed under the action of gamma-neutron pulse the forecasting parameter IOLMAX – maximum low-level output current is measured as low-level output voltage 1,0-2,0 В before and in process of radiation influences. Value of IOLMAX defines the load of output transistors and the estimation of its change allows to forecast the value of free-failure functioning level in conditions of pulse gamma-neutron radiation influence.

Keywords: pulse gamma-neutron radiation, level of free-failure functioning, bipolar integrated circuits, radiation resistance, prediction.

Radiation effects in powerful MOS devices caused by bremsstrahlung pulse of the accelerator and action of separate neutrons with energy of 14 MeV are researched. On the basis of temperature and dose dependence, it is shown that the single event effect is caused by field multiplication of the charge carriers generated in interaction of a thermonuclear neutron with substance.

Keywords: MOS devices, thermonuclear neutrons, single events, catastrophic failures.
