  • Patent number: 10187011
    Abstract: Dual gate FD-SOI transistors are used as MOSFET capacitors to replace passive well capacitors in analog microcircuits. Use of the dual gate FD-SOI devices helps to reduce unstable oscillations and improve circuit performance. A thick buried oxide layer within the substrate of an FD-SOI transistor forms a capacitive dielectric that can sustain high operating voltages in the range of 1.2 V-3.3 V, above the transistor threshold voltage. A secondary gate in the FD-SOI transistor is used to create a channel from the back side so that even when the bias voltage on the first gate is small, the effective capacitance remains higher. The capacitance of the buried oxide layer is further utilized as a decoupling capacitor between supply and ground. In one example, a dual gate PMOS FD-SOI transistor is coupled to an operational amplifier and a high voltage output driver to produce a precision-controlled voltage reference generator.

  • Patent number: 9673094
    Abstract: A semiconductor device having a via hole whose side surface is covered with nitride metal is disclosed. The via hole is formed within an insulating region that surrounds a conductive region, where both regions are made of nitride semiconductor materials. The via hole is filled with a back metal and in side surfaces thereof is covered with the nitride metal which is heat treated at a preset temperature for a preset period. Nitrogen atoms in the nitride metal diffuse into the nitride semiconductor materials in the insulating regions and compensate nitride vacancies therein. The interface between the nitride metal and the nitride semiconductor material is converted into an altered region that shows enough resistivity to suppress currents leaking from the via hole metal to the conductive region of the nitride semiconductor material.
