    摘要: In an LDMOS-SCR ESD protection structure gate voltage of an ESD protection LDSCR is defined by connecting the gate to the source of a reference LDSCR. The reference LDSCR is implemented as a self-triggering device in which the snapback drain-source voltage (avalanche breakdown voltage) is controlled to be lower than that for the major LDSCR by adjusting the RESURF layer-composite overlap for the reference LDSCR to be different to that of the major LDSCR.

    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.

    摘要: A diode for alternating current (DIAC) electrostatic discharge (ESD) protection circuit is formed in a silicon germanium (SiGe) hetrojunction bipolar transistor (HBT) process that utilizes a very thin collector region. ESD protection for a pair of to-be-protected pads is provided by utilizing the base structures and the emitter structures of the SiGe transistors.
