    摘要: The snapback characteristics of the parasitic NPN structure inside an NMOS device are used to write and store information in the device by periodically triggering the device from the high impedance state to the low impedance state using the self turn-on characteristics of the device under elevated voltage. To minimize power consumption, and thus overheating, in the “on” state, a pulsed mode operation is combined with dV/dt triggering powering the device at a constant Vdd pulse amplitude.

    摘要: In a multiple input ESD protection structure, the inputs are isolated from the substrate by highly doped regions of opposite polarity to the input regions. Dual polarity is achieved by providing a symmetrical structure with n+ and p+ regions forming each dual polarity input. The inputs are formed in a p-well which, in turn, is formed in a n-well. Each dual polarity input is isolated by a PBL under the p-well, and a NISO underneath the n-well. An isolation ring separates and surrounds the inputs. The isolation ring comprises a p+ ring or a p+ region, n+ region, and p+ region formed into adjacent rings.

    摘要: In a method and structure for current balancing the emitter current in a multi-finger n-emitter of a BJT or BSCR, back-end or polysilicon resistors are applied between the emitter fingers and the power rail, with the resistors chosen to be larger the closer the emitter fingers are to the collector.
