The effects of moisture on radiation-induced charge buildup in the oxides of a 0.35 μSOI technology are explored. Data show no observable effects of moisture-related aging on radiation hardness. These results are in contrast to those of previous work performed on bulk MOS technologies fabricated in the 1980s. The cause of these differences do not appear to be due to differences in final chip passivation layers. Instead, other processing variables (e.g., thicker overlayers) may account for these differences. In any case, the SOI technology results indicate that not all advanced technologies exposed to moisture are necessarily susceptible to enhanced radiation-induced degradation. © 2010 IEEE.

The amounts of charge collection by single-photon absorption to that by two-photon absorption laser testing techniques have been directly compared using specially made SOI diodes. Details of this comparison are discussed.

Proton-induced singl -event effects hardness assurance guidelines are developed to address issues raised by recent test results in advanced IC technologies for use in space environments. Specifically, guidelines are developed that address the effects of proton energy and angle of incidence on single-event latchup and the effects of total dose on single-event upset. The guidelines address both single-event upset (SEU), single-event latchup (SEL), and combined SEU and total ionizing dose (TID) effects. © 2006 IEEE.

Large and unexpected radiation-induced voltage shifts have been observed for some MOS technologies exposed to moisture. The mechanisms for these large voltage shifts and their implications for long-term aging are discussed.

We irradiated floating gate (FG) memories with NOR and NAND architecture by using different TID sources, including 2 MeV, 98 MeV, and 105 MeV protons, X-rays, and γ-rays. Two classes of phenomena are responsible for charge loss from programmed FGs: the first is charge generation, recombination, and transport in the dielectrics, while the second is the emission of electrons above the oxide band. Charge loss from programmed FGs irradiated with protons of different energy closely tracks results from γ-rays, whereas the use of X-rays results in dose enhancement effects. © 2007 IEEE.
