  • Publication number: 20130228550
    Abstract: There is provided dry etching apparatus including a stage on which a wafer is placed, an antenna electrode, a high frequency power supply, a shower plate, and an RF bias power supply. Further, a bias path controller is provided on the side of the antenna electrode. The bias path controller resonates in series with the static reactance formed by the shower plate with respect to the frequency of the RF bias. Then, the bias path controller changes and grounds the impedance by the variable inductive reactance. With this mechanism, highly uniform etching can be achieved even if a shower plate of quartz is used for corrosive gases.

    Abstract: [Object] To realize processing for switching a reproduction state from broadcast data to network data and resuming the reproduction of the original broadcast data. [Solving Means] A browser (241) acquires, via a network, an XML-AIT having a content equivalent to a broadcast AIT defining a life cycle of a broadcast application while a VoD content is reproduced after being switched from the broadcast application. The browser (241) manages the broadcast application based on the XML-AIT and resumes the reception of the broadcast application after the reproduction of the VoD content is ended. With this structure, processing of separating two transport streams at the same time becomes unnecessary, and one demultiplexer (23) only needs to be provided.
