  • Inductive/capacitive hybrid plasma source and system with such chamber
    Patent number: 9034143
    Abstract: A plasma processing chamber having capacitive and inductive coupling of RF power. An RF power source is connected to an inductive coil and to a top electrode via a variable capacitor to control the ratio of power applied to the coil and electrode. The bottom electrode, which is part of the chuck holding the substrates, is floating, but has parasitive capacitance coupling to ground. No RF bias is applied to the chuck and/or the substrate, but the substrate is chucked using DC power. In a system utilizing the chamber, the chuck is movable and is loaded with substrates outside the chamber, enter the chamber from one side for processing, exit the chamber from an opposite side after the processing, and is unloaded in an unloading chamber. The chuck is then transported back to the loading chamber. Substrates are delivered to and removed from the system using conveyor belts.

  • Transmission system using dying gasp
    Patent number: 9007228
    Abstract: An Ethernet-based transmission system using a dying gasp according to the present invention includes an SMPS for supplying power to an Ethernet-based lower level system, detecting a state of a power fault, and outputting a dying gasp alarm signal. A CPU receives the dying gasp alarm signal, and generates and transmits an alarm packet. A PHY chip receives the alarm packet, and uplinks the alarm packet so that the alarm packet is transferred to a higher level stage. An L3 switch receives the alarm packet and determines whether a power fault has occurred in the lower level system. Accordingly, the present invention applies a dying gasp to an Ethernet-based or EPON-based transmission system and is then capable of generating and transmitting an alarm packet so that when a power fault occurs, a device in a higher level network can rapidly determine the occurrence of the power fault.
