  • Publication number: 20090133622
    Abstract: A plasma assisted apparatus for organic film deposition, comprising: a plasma chamber, capable of thermally cracking a precursor in the plasma chamber; and a deposition chamber, being channeled with the plasma chamber for receiving the thermally cracked precursor. In an exemplary embodiment, the deposition chamber further comprises a substrate device, being provided for the thermally cracked precursor to deposit thereon to form an organic film. As the plasma chamber is separated from the deposition chamber in the aforesaid apparatus, a low-temperature film deposition process can be used for forming organic films while preventing the substrate device from being bombarded directly by plasma. In addition, as there is a flow guiding device arranged at the outlet of the plasma chamber, the thermally cracked precursor is guided or disturbed and thus is prevented from overly concentrating at the outlet or the center of the substrate device.

  • Publication number: 20060200689
    Abstract: A signal transmitting circuit includes a driving circuit, and a plurality of receiving circuits receiving signals transmitted from the driving circuit. Each of the receiving circuits is coupled to the driving circuit consecutively via a transmission line. A voltage regulator is coupled to the driving circuit and the receiving circuits and provides power to the driving circuit and the receiving circuits. A number of capacitors are coupled between the voltage regulator and the ground for filtering the noise of the power output from the voltage regulator. The capacitors between the voltage regulator and the north bridge chipset filtering the noise of the power output from the voltage regulator maintain signal integrity as the terminal resistor does. It is of advantage that the signal transmitting circuit is simple to manufacture and very suitable for mass production.
