    摘要: In an ESD device for fast switching applications based on a BSCR or NLDMOS-SCR, an anode junction control electrode is provided by not connecting the anode electrode to the collector of the BSCR or to the drain of the NLDMOS-SCR, and a cathode junction control electrode is provided by forming an additional n+ region in the BSCR or an additional p+ region in the p-well of the NLDMOS-SCR. The triggering voltage of the ESD device is adjusted after a time delay by controlling one or both of the control electrodes using an RC-timer-driver circuit.

    摘要: In a SiGe BJT process, a diode is formed by defining a p-n junction between the BJT collector and BJT internal base, blocking the external gate regions of the BJT and doping the emitter poly of the BJT with the same dopant type as the internal base thereby using the emitter contact to define the contact to the internal base. Electrical contact to the collector is established through a sub-collector or by means of a second emitter poly and internal base both doped with the same dopant type as the collector.

    摘要: A MEMS magnetic flux switch is fabricated as a ferromagnetic core. The core includes a center cantilever that is fabricated as a free beam that can oscillate at a resonant frequency that is determined by its mechanical and material properties. The center cantilever is moved by impulses applied by an associated motion oscillator, which can be magnetic or electric actuators.
