  • Patent number: 8016592
    Abstract: A thermal processing system is disclosed. The thermal processing system includes a transfer stage, one or more thermal processing chambers and an interface to a deposition equipment. The transfer stage is provided to receive workpieces for thermal processing. Further the transfer stage is provided as a mechanism to move workpieces from one chamber to another chamber. The thermal processing chamber includes a heat manipulation system to heat up or cool down the workpieces. The thermal processing chamber is designed to accommodate a platform that positions each of the workpieces vertically. As a result, all workpieces are moved together with the platform to be transferred, for example, from one chamber to another chamber. Depending on implementation, the platform may be implemented to include a fixture or a plurality of fixtures, where all of the workpieces may be removably held up by the fixture or each of the workpieces is removably held up by one of the fixtures.

  • Publication number: 20090169341
    Abstract: Techniques for transferring workpieces from one chamber to another chamber are disclosed. According to one aspect of the techniques, a treatment system includes a load lock chamber, a transfer chamber and one or more process chambers. The load lock chamber is provided to receive workpieces for treatment or process in one or more process chambers. The transfer chamber is provided as a mechanism to move workpieces from one chamber to another chamber. The process chamber includes a set of electrodes used to treat the workpieces with other materials. To facilitate the transfer of the workpieces, the process chamber is designed to position each of the workpieces vertically between a pair of electrodes, where each of the workpieces is removably held up by a fixture. Depending on implementation, the workpieces may be mounted on one fixture or multiple fixtures respectively. The fixture(s) is then mounted to a moving mechanism that facilitates the fixture(s) to move from one chamber to another chamber.

  • Publication number: 20080107209
    Abstract: A slicer circuit is disclosed. The slicer circuit has the feature that a counting-circuit is employed to count the number of continuous times of signals in a same level continuous outputted from the comparator thereof, and when the number of continuous times reaches a preset value, a control signal is output to make a resistance circuit consisting of dynamic devices open, so as to largely delay the up-shift or down-shift speed of an input DC reference level and enable the slicer circuit to continue to judge the input signal correctly according to the input DC reference level.

  • Publication number: 20060264196
    Abstract: A super-regenerative receiver with a damping resistor receives an input signal to produce an output signal. The super-regenerative receiver includes a sawtooth generator, a bias source, an oscillator circuit, and a quench control circuit. The oscillator circuit includes a resonant circuit, a damping resistor, an amplifier and a quench switch. The damping resistor damps the ringing signal when turning off the quench switch.
