    摘要: Disclosed are lateral double diffused metal oxide semiconductor (LDMOS) transistors having a uniform threshold voltage and methods for manufacturing the same. The methods include forming a polysilicon layer over the semiconductor substrate including a shallow trench isolation region, etching a portion of the polysilicon layer over an active region, implanting first conductive-type impurity ions using the polysilicon layer as a mask to form a first conductive-type body region, implanting second conductive-type impurity ions using the polysilicon layer as a mask to form a second conductive-type channel region in the first conductive-type body region, removing the polysilicon layer, forming gate electrodes in the polysilicon-free region, and forming a source region and a drain region in the first conductive-type body region using the gate electrode and the shallow trench isolation as ion-implantation masks.

    摘要: An apparatus and method for encoding/decoding a multi-channel signal may be provided. The apparatus of encoding a multi-channel signal may insert information about whether to encode a phase parameter indicating phase information of a plurality of channels, included in the multi-channel signal, in a bitstream of the multi-channel signal. The apparatus of decoding a multi-channel signal may determine whether to up-mix a mono signal using the phase parameter based on the information about whether to encode.

    摘要: A method and apparatus of effectively encoding and decoding a high-frequency signal of a multi-channel audio are provided. A multi-channel audio decoding apparatus may down-mix a multi-channel audio input signal, expand a number of channels of the down-mixed signal, select at least one of the expanded channel signal, extract a parameter indicating a characteristic relation between the selected signal and the multi-channel audio input signal, and encode the down-mixed signal and the extracted parameter.
