  • Patent number: 9786489
    Abstract: A method of cleaning post-etch residues on a copper line includes providing a copper line which is divided into a first region and a second region. A dielectric layer is formed on the copper line. After that, the dielectric layer is etched to form openings in the dielectric layer. A number of openings within the first region is more than a number of openings in the second region. During the etching process, a potential difference is formed between the first region and the second region of the copper line. Finally, the dielectric layer and the copper line are cleaned by a solution with a PH value. The PH value has a special relation with the potential difference.

  • Patent number: 9431256
    Abstract: A method for manufacturing a semiconductor device includes the following steps. At first, two gate stack layers are formed on a semiconductor substrate, wherein each of the gate stack layers includes a top surface and two side surfaces. A conductive material layer is deposited to conformally cover the top surface and the two side surfaces of each of the gate stack layers. Then, a cap layer is deposited to conformally cover the conductive material layer. Finally, the cap layer and the conductive material layer above the top surface of each of the gate stack layers are removed to leave the cap layer adjacent to the two side surfaces of each of the gate stack layers and covering a portion of the conductive material layer.

    Abstract: The present disclosure provides a power supply system. The power supply system includes a plurality of power supply devices connected in parallel. Output terminals of the plurality of power supply devices are coupled to a common supply line. Each of the plurality of power supply devices includes a DC-to-DC converter, a transformer, a switching control device, a rectifying device, and a judging device. The judging device receives a feedback voltage, an error signal and a second AC voltage to determine whether the power supply device is normal, wherein the feedback voltage is a voltage division of an output voltage on the common supply line, the error signal is an output of the switching control device, and the second AC voltage is retrieved from a second winding set of the transformer.

  • Patent number: 9030794
    Abstract: An electronic fuse apparatus is connected between a power side and a system side. The electronic fuse apparatus mainly includes an electronic fuse, a short-circuit protection switch, a current-sensing module, and a digital control module. The current-sensing module detects an operating current which flows from the power side to the system side. The digital control module generates a control signal to control the electronic fuse. When the current-sensing module detects that the operating current is over-current, the digital control module generates the high-level control signal to turn off the electronic fuse, thus providing an over-current protection. When a short-circuit fault occurs at the system side, the short-circuit protection switch is turned on to turn off the electronic fuse, thus providing a short-circuit protection.

  • Publication number: 20080018473
    Abstract: Techniques are described for protecting components of an RFID tag from electrostatic discharge. For example, an RFID tag includes a conductive cage that shields the components of the RFID tag from electrostatic discharge. The conductive cage includes a first conductive shield on a first side of a substrate of the RFID tag and a second conductive shield on a second side of the substrate. The first conductive shield is positioned on the first side of the substrate to cover an integrated circuit (IC). The second conductive shield is positioned on the second side of the substrate, and is substantially opposite from the first conductive shield. The first and second conductive shields are interconnected by one or more conductors. In this manner, the interconnected conductive shields form a conductive cage that protects the IC from electrostatic discharge.
