Abstract: Devices with increased susceptibility to ionizing radiation feature multiple parasitic transistors having leakage currents that increase with total ionizing dose (TID) due to negative threshold shifts from radiation-induced charge buildup in the field oxide. Leakage currents of parasitic edge transistors associated with active region sidewalls under a gate are enhanced using branching gate patterns that increase the number of these sidewalls. Other variations combine parasitic edge transistors with parasitic field transistors formed under the field oxide between active regions, or between n-wells and active regions. Arrays of such devices connected in parallel further multiply leakage currents, while novel compact designs increase the density and hence the sensitivity to TID for a given circuit area. These NMOS-based radiation-intolerant devices can be integrated with more radiation-tolerant CMOS integrated circuits using commercial processes, to produce circuits having a level of radiation intolerance required for export, or to be used as dosimeters.

Abstract: A dosimetry system for monitoring radiation exposure for a device under inspection comprises a support structure, a plurality of detectors, a signal processing unit, and a computing device. The support structure includes an upper surface on which the device under inspection is positioned. The detectors are positioned in proximity to the device under inspection. Each detector is configured to detect radiation and generate a radiation electronic signal whose level varies according to an amount of radiation to which the detector is exposed. The signal processing unit is configured to receive the radiation electronic signal from each detector and output data derived from the radiation electronic signals. The computing device is configured to receive the data from the signal processing unit and determine an accumulated radiation level for each detector.

CPC classification number: G01T1/026
Abstract: Absorbed ionizing particles differentially effect first and second acquiring circuit stages configured to respectively generate first and second acquisition signals. Each acquisition signal has a characteristic that is variable as a function of an amount of absorbed ionizing particles. A measuring circuit generates, on the basis of the first and second acquisition signals, a relative parameter indicative of a relationship between the variable characteristics. A computation of a total ionizing dose is made using a 1st- or 2nd-degree polynomial relationship in the relative parameter.

Abstract: Three semiconductor detectors are installed at positions where incidence of radiation on a scintillation detector is not blocked, at equal intervals centered on a central axis of the scintillation detector and at equal angles with respect to a plane which is at a right angle to the central axis. An energy compensation factor is determined on the basis of an average pulse height value obtained from a second pulse height spectrum obtained by analog voltage pulses which are output from these semiconductor detectors, and energy characteristics of a high-range dose rate obtained by a direct-current voltage which is output from the scintillation detector are compensated for.
