  • Publication number: 20240429239
    Abstract: Structures and methods for better optimizing the performance of all the circuitry of an SOI IC. Embodiments include SOI IC having dual-thickness active areas, such that digital and non-RF analog circuitry may be fabricated on a relatively thin active layer while RF circuitry may be fabricated on a relatively thick active layer. Fabrication of RF circuitry on the relatively thick active layer allows for improvements to the RON*COFF figure of merit for the FET devices, and for optimizations not feasible for RF circuitry fabricated on a relatively thin active layer. Two methods of forming shallow-trench isolation (STI) structures in both active layers are described. A first method forms STIs in the thin active layer first, then in the thick active layer. A second method forms STIs in the thin active layer first and partial STIs in the thick active layer, then completes the partial STIs in the thick active layer.

  • Publication number: 20240421225
    Abstract: High-voltage transistors that may be fabricated in a standard low-voltage process. Embodiments include integrated circuits that combine, in a unitary structure, an LDMOS FET device that includes one or more dummy polysilicon structures (DPS's) overlying a drift region and comparable in configuration to the FET gate, and interstitial implant resistance pockets (IRP) formed within the drift region between the gate and an adjacent DPS and between each pair of adjacent DPS's. The IRPs may be augmented with floating contacts to remove heat from the drift region and provide additional shielding of the drain contact from the nearest edge of the gate. The IRPs may be biased to modulate the conductivity of the drift region. The DPS's may be biased to modulate the conductivity of the drift region, and in such a way as to protect each DPS from excessive and potentially destructive voltages.

  • Patent number: 9416533
    Abstract: A device for damping a transmitted vibration by the moment of inertia of a fly wheel and the adjustable resistance force of a viscous magnetic fluid to allow the viscous magnetic fluid exerts its property even under no external power source. A sleeve with an attached ball nut is disposed in a first cylinder so as to reciprocate. The reciprocating motion of the sleeve is converted into a rotational motion by a ball screw to rotate a fly wheel in a second cylinder and a generator rotating shaft. Between the fly wheel and the inner surface of the second cylinder, a sealed space is formed in which a viscous magnetic fluid is sealed. A magnetic field generating unit which generates a magnetic field running across the sealed space with the fly wheel serving as a part of a magnetic circuit is disposed on the inner circumference of the second cylinder.
