  • Semiconductor device and methods of forming the same
    Patent number: 11973027
    Abstract: A semiconductor device and a method of forming the same are provided. The semiconductor device includes a substrate, a gate structure, a dielectric structure and a contact structure. The substrate has source/drain (S/D) regions. The gate structure is on the substrate and between the S/D regions. The dielectric structure covers the gate structure. The contact structure penetrates through the dielectric structure to connect to the S/D region. A lower portion of a sidewall of the contact structure is spaced apart from the dielectric structure by an air gap therebetween, while an upper portion of the sidewall of the contact structure is in contact with the dielectric structure.

  • Power conservation in power sourcing equipment
    Patent number: 10693665
    Abstract: A method is provided to conserve power in a power sourcing equipment (PSE) that provides a PSE port voltage at PSE ports. The method includes, in response to detecting a powered device (PD) is connected to the PSE port, providing a power supply output voltage at a default value and turning on the PSE port. After turning on the PSE port, the method includes determining the PSE port voltage. When the PSE port voltage is greater than a threshold value, the method includes decreasing the power supply output voltage.
