  • Publication number: 20190221639
    Abstract: A method for fabrication a nanosheet device includes providing forming a stacked layer on a substrate, having first material layers and second material layers in different materials, alternatingly stacked up. The stacked layer is patterned to a stacked fin. A dummy stack is formed on the stacked fin. An etching back process is performed with the dummy stack with spacers to etch the stacked fin and expose the substrate. Laterally etches the first material layers and the second material layers, to have indent portions. Inner spacers fill the indent portions. A first/second source/drain layer is formed on the substrate at both sides of the dummy stack. Etching process is performed to remove the dummy gate of the dummy stack and the selected one of the first material layers and the second material layers between the inner spacers. Metal layer fills between the spacers and the inner spacers.

  • Publication number: 20170202104
    Abstract: This invention is related to a carbon-coated copper foil for heat dissipation, which comprising a copper foil, a metal-dielectric layer, and a carbon film. The copper foil is formed with a first rough surface, and the metal-dielectric layer is coated on the first rough surface of the copper foil. The metal-dielectric layer is formed with a second rough surface along with the first rough surface, and the carbon film is embedded and coated on the second rough surface. Accordingly, the rough surfaces of the copper foil and the metal-dielectric layer make the carbon atoms attach firmly on the copper foil. Furthermore, the carbon film formed by bonded carbon atoms has high thermal conductivity, so it can dramatically improve the effect of the heat dissipation of the electronics and extend the use life of the electronics.

  • Patent number: 9088204
    Abstract: A control circuit of a switching regulator includes a control pin for coupling with an external resistor; a resistor detecting circuit for detecting a resistance of the external resistor; a current generating module for generating a corresponding control current according to a detection result of the resistor detecting circuit; an oscillating circuit for generating a clock signal; and a mode-switching circuit. When the mode-switching circuit configures the oscillating circuit to operate in a resistor-controlled mode, the oscillating circuit generates the clock signal according to the control current so that the clock signal has a frequency corresponding to the resistance of the external resistor. When the mode-switching circuit configures the oscillating circuit to operate in a signal-controlled mode, the oscillating circuit generates the clock signal according to an external synchronous signal coupled with the control pin so that the clock signal is synchronized with the external synchronous signal.

  • Publication number: 20100164462
    Abstract: A DC-DC converter includes a switch circuit, a feedback circuit, an error amplifier, a soft-start circuit, and a signal modulation circuit. The switch circuit receives an input voltage and charges/discharges an inductor based on a switch control signal, thereby providing an output voltage. The feedback circuit provides a corresponding feedback voltage based on the output voltage. The error amplifier generates a comparing voltage based on the feedback voltage and a reference voltage. The soft-start circuit provides a ramp clamping voltage, which is outputted as the comparing voltage when the comparing voltage is larger than the ramp clamping voltage. The signal modulation circuit generates the switch control signal based on the comparing signal and a periodic signal.
