Abstract
An array of radiation sensors or detectors is integrated within a three-dimensional semiconductor IC. The sensor array is located relatively close to the device layer of a circuit (e.g., a microprocessor) to be protected from the adverse effects of the ionizing radiation particles. As such, the location where the radiation particles intersect the device layer can be calculated with coarse precision (e.g., to within 10 s of microns).
