  • Patent number: 11923243
    Abstract: A method for manufacturing a semiconductor structure includes preparing a dielectric structure formed with trenches respectively defined by lateral surfaces of the dielectric structure, forming spacer layers on the lateral surfaces, filling an electrically conductive material into the trenches to form electrically conductive features, selectively depositing a blocking layer on the dielectric structure, selectively depositing a dielectric material on the electrically conductive features to form a capping layer, removing the blocking layer and the dielectric structure to form recesses, forming sacrificial features in the recesses, forming a sustaining layer to cover the sacrificial features; and removing the sacrificial features to obtain the semiconductor structure formed with air gaps confined by the sustaining layer and the spacer layers.

  • Publication number: 20240069618
    Abstract: The disclosure provides a power management method. The power management method is applicable to an electronic device. The electronic device is electrically coupled to an adapter, and includes a system and a battery. The adapter has a feed power. The battery has a discharge power. The power management method of the disclosure includes: reading a power value of the battery; determining a state of the system; and discharging power to the system, when the system is in a power-on state and the power value is greater than a charging stopping value, by using the battery, and controlling, according to the discharge power and the feed power, the adapter to selectively supply power to the system. The disclosure further provides an electronic device using the power management method.

  • Publication number: 20190074640
    Abstract: An adapter module including an adapter and a power cord is provided. The adapter includes a first interface, at least a second interface coupled with at least a load, an identifying circuit having a sensing switch configured at the first interface, a controller, and a detecting circuit. The first interface is provided for inserting by a connector of the power cord. The sensing switch changes its on/off state depending on whether the first connector provides a trigger. A first message is generated if the first connector provides the trigger. The controller is coupled to the identifying circuit and receives the first message. The detecting circuit is coupled between the first interface and the second interface for detecting a power parameter value, and provides a second message to the controller. The controller sends a warning message according to the first message and the second message.

  • Patent number: 9450453
    Abstract: An uninterruptible power supply (UPS) system with energy feedback to chargers and sinusoidal output charges a battery pack through a first charger under a mains mode. Under a battery mode, the UPS boosts DC voltage outputted from the battery pack to a higher voltage level through a DC-to-DC conversion module, converts the DC voltage to a sinusoidal AC voltage through a DC-to-AC conversion module, and supplies the sinusoidal AC voltage to a load. When the load has energy storage elements and discharged energy occurs in a power supply loop, a micro-controller unit can control the discharged power to charge the battery pack through a second charger, thereby solving the issue of the discharged power from the energy storage elements of the load and enhancing the operational efficiency of the UPS.
