摘要： A circuit and methods for mitigating radiation-induced Single Event Effects (SEE) in Silicon-on-Insulator (SOI) Complementary Metal-Oxide-Semiconductor (CMOS) integrated circuits are presented. A primary logic output is generated from a primary logic gate in response to an input. A redundant logic output is generated from a redundant logic gate that duplicates the primary logic output in response to the input if an SEE is not present. An interleaved C-gate output is generated from an interleaved C-gate that emulates an inverter output when the primary logic output and the redundant logic output match, and does not changes its output when the primary logic output and the redundant logic output do not match during the SEE.

摘要： Disclosed is a semiconductor structure that incorporates a capacitor for reducing the soft error rate of a device within the structure. The multi-layer semiconductor structure includes an insulator-filled deep trench isolation structure that is formed through an active silicon layer, a first insulator layer, and a first bulk layer and extends to a second insulator layer. The resulting isolated portion of the first bulk layer defines the first capacitor plate. A portion of the second insulator layer that is adjacent the first capacitor plate functions as the capacitor dielectric. Either the silicon substrate or a portion of a second bulk layer that is isolated by a third insulator layer and another deep trench isolation structure can function as the second capacitor plate. A first capacitor contact couples, either directly or via a wire array, the first capacitor plate to a circuit node of the device in order to increase the critical charge, Qcrit, of the circuit node.

摘要： Semiconductor structures and methods for suppressing latch-up in bulk CMOS devices. The structure comprises a damage layer formed in a substrate, a first doped well formed in the substrate, and a second doped well formed in the substrate proximate to the first doped well. The damage layer extends within the substrate to intersect the first and second doped wells. The damage layer may be formed by ion implantation followed by growth of an epitaxial layer to segregate the active device regions from the damage layer.

摘要： Issues that are addressed in accordance with at least one presently preferred embodiment of the present invention, are: improvements upon the time it takes to physically swap degraders (done previously by hand); the safety involved in doing so, since the degraders become highly radioactive; possible improved energy resolution and beam stability if the accelerator can be left running continuously; and in-situ monitoring of beam current, beam position and stability. Particularly contemplated are methods and arrangements for changing degraders automatically, not manually, and in a safe manner.

摘要： Semiconductor methods and device structures for suppressing latch-up in bulk CMOS devices. The method comprises forming a trench in the semiconductor material of the substrate with first sidewalls disposed between a pair of doped wells, also defined in the semiconductor material of the substrate. The method further comprises forming an etch mask in the trench to partially mask the base of the trench, followed by removing the semiconductor material of the substrate exposed across the partially masked base to define narrowed second sidewalls that deepen the trench. The deepened trench is filled with a dielectric material to define a trench isolation region for devices built in the doped wells. The dielectric material filling the deepened extension of the trench enhances latch-up suppression.
