Component potentials and electric field strengths are examined before and after a structure ground discharge event. Field reversal after the discharge suggests that favourable conditions exist for charge dissipation from the internal dielectrics at this point in time. Electric field strength dependent, this can be either spontaneous or drift related. This work was realized using a tool of two components. The charging cycle is calculated using a modified ITS-ACCEPT code. The resulting charge distribution is used as input to a 3D Poisson equation solver.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.

They have been categorized according to their orbital location, amount of shielding and upset multiplicity. The mechanisms responsible have been identified from ground testing of identical memories using both energetic ions and pulsed laser light. With the aid of bit-maps (generated with the pulsed laser) multiple-bit upsets could, in most cases, be attributed to one of three mechanisms, i.e., charge diffusion away from an ion strike, an ion strike to control circuitry, and an ion track intersecting a number of memory cells. Heavy-ion strikes to peripheral circuits on the memory chip generated multiple-bit upsets involving as many as twenty-one cells. Proton-induced multiple-bit upset rates have been calculated for the spacecraft orbit, and the results show good agreement with measured rates.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.

Namely, X-rays, 8 MeV electrons, and three ion beams with different LETs values have been used on large area MOS capacitors with 4-nm thick oxides. Small oxide fields were applied during irradiation, reaching 3 MV/cm at most. For ionizing radiation with relatively low LET (<10 MeV cm/sup 2//mg), only Radiation Induced Leakage Current (RILC) was observed, due to the formation of neutral defects mediating electron tunneling via a single oxide trap. For high LET values, instead, the gate leakage current could be described by an empirical relation proper of Soft Breakdown (SB) phenomena detected after electrical stress. Moreover, the typical random telegraph signal noise feature of this Radiation induced Soft Breakdown (RSB) currents was observed during and after irradiation. RSB can be attributed to conduction through a multi-defect path across the oxide, produced by the residual damage of dense ion tracks. The oxide field applied during irradiation enhances the RSB intensity, but RSB can be achieved even for irradiation at zero field, being LET the main factor leading to RSB activation. The dose dependence of both RILC and QB have been investigated, showing a quasi linear kinetics with the cumulative dose. We have also studied the effect of modifying the angle of incidence of the ion beam on the intensity of the gate leakage current.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.
