    • A semiconductor device having an EDMOS transistor and a method for forming the same are provided. The semiconductor device includes source and drain regions formed separately in a semiconductor substrate, a first gate insulating layer filling a trench formed in the substrate between the source and drain regions, the first gate insulating layer being adjacent to the drain region and separated from the source region, a second gate insulating layer formed over the substrate between the first gate insulating layer and the source region, the second gate insulating layer being thinner than the first gate insulating layer, a gate electrode formed over the first and second gate insulating layers, and a doped drift region formed in the substrate under the first gate insulating layer, the doped drift region being in contact with the drain region. This reduces the planar area of the EDMOS transistor, thereby achieving highly integrated semiconductor devices.

    • Provided is a method for fabricating a semiconductor device. The method includes implanting ions into an n-channel metal oxide semiconductor (NMOS) region of a semiconductor substrate so as to form a channel. The implanting can be performed by implanting boron ions at an ion implanting energy of 20 keV to 100 keV using a photoresist layer formed on the semiconductor substrate as an ion implanting mask for inhibiting ions from entering the semiconductor substrate below the photoresist layer. The photoresist layer can be a mid-ultra-violet photoresist having a reduced thickness.

    • A receiver which receives both HDTV and NTSC signals, and a method for selecting received signals, are provided. According to this receiver and method, a broadcasting mode and a channel mode are set by the user. When the broadcasting mode is set to be an NTSC mode, only an NTSC signal is selected to be displayed. When the broadcasting mode is set to be an HDTV mode, only a high-definition (ATV) signal is selected to be displayed. When the judged broadcasting mode is an automatic mode, a judgement is made by the receiver whether an NTSC signal exists in a received signal. If no NTSC signal is present in the received signal, the ATV signal is selected for display. If the NTSC signal exists in the currently-received signal, selection between NTSC and ATV signals is made based on the channel mode set by the user. If the channel mode is set to NTSC, then the NTSC signal is selected for display. If the channel mode is set to HDTV, then the ATV signal is selected for display. Therefore, the HDTV and NTSC signals can both be received, and when both NTSC and HDTV signals exist in a channel, one of them can be selectively received.
    • 同时提供接收HDTV和NTSC信号的接收机以及接收信号的选择方法。 根据该接收方法,用户设定广播模式和频道模式。 当广播模式被设置为NTSC模式时,仅选择显示NTSC信号。 当广播模式被设置为HDTV模式时,仅选择显示高分辨率(ATV)信号。 当所判断的广播模式是自动模式时,由接收机判断接收到的信号中是否存在NTSC信号。 如果接收信号中没有NTSC信号,则选择ATV信号进行显示。 如果NTSC信号存在于当前接收到的信号中,则基于由用户设置的信道模式进行NTSC和ATV信号之间的选择。 如果通道模式设置为NTSC,则选择NTSC信号进行显示。 如果频道模式设置为HDTV,则选择ATV信号进行显示。 因此,可以接收HDTV和NTSC信号,并且当NTSC和HDTV信号都存在于信道中时,可以选择性地接收其中的一个。

    • A trellis-coded modulation (TCM) decoder of a high-definition television (HDTV) receiver is disclosed for use in US-type terrestrial broadcasting, as is a corresponding decoding method. The TCM decoder optionally uses a NTSC-reject comb filter to remove the interference from a co-channel NTSC-type signal. When the input HDTV signal has been passed through the NTSC rejection filter, an 8-state decoding mode is appropriate and a segment sync suspension unit is used to directly connect the data before and after a twelve symbol segment sync. When the input HDTV signal has not been passed through the NTSC rejection filter, an 4-state decoding mode is appropriate and the input HDTV signal is passed unchanged (i.e., without use of the segment sync suspension unit). A field delay directly connects the data of the data segment just before the field sync segment to the data of the data segment just after the field sync segment. A Viterbi decoder decodes the output of the field delay in both an 8-state case and a 4-state case. Therefore, decoding is performed in consideration of the effects of uncoded segment sync and field sync signals, thereby achieving stable decoding.
    • 公开了用于美式地面广播的高分辨率电视(HDTV)接收机的网格编码调制(TCM)解码器,以及相应的解码方法。 TCM解码器可选地使用NTSC抑制梳状滤波器来消除来自同频道NTSC型信号的干扰。 当输入的HDTV信号通过NTSC抑制滤波器时,8状态解码模式是合适的,并且使用分段同步停止单元直接连接十二符号段同步之前和之后的数据。 当输入的HDTV信号尚未通过NTSC抑制滤波器时,4状态解码模式是合适的,输入的HDTV信号不变(即不使用片段同步悬架单元)。 场延迟直接将场同步段之前的数据段的数据直接连接到场同步段之后的数据段的数据。 维特比解码器在8状态情况和4状态情况下解码场延迟的输出。 因此,考虑到未编码段同步和场同步信号的影响进行解码,从而实现稳定的解码。
