    • A semiconductor memory device having an advanced data input/output path is provided to prevent the degradation of operation speed due to loads of peripheral circuits connected to a bit line, and to reduce chip size by reducing the number of column pass gates. In a semiconductor memory device having a data input/output path, a first and a second memory cell cluster(MCC1,MCC2) are divided in operation while sharing an equal bit line pair of the data input/output path. A third and a fourth memory cell cluster(MCC3,MCC4) are connected to a word line connected to the first and the second memory cell cluster, and are divided in operation while sharing a bit line pair different from the bit line pair. A column pass gate(84) switches one of the bit line pairs connected to the four memory cell clusters to a common sense amplifier in response to a column selection signal, in order to constitute the data input/output path.
    • 提供具有高级数据输入/输出路径的半导体存储器件以防止由于连接到位线的外围电路的负载而引起的操作速度的降低,并且通过减少列通过门的数量来减小芯片尺寸。 在具有数据输入/输出路径的半导体存储器件中,第一和第二存储器单元簇(MCC1,MCC2)在共享数据输入/输出路径的等位线对的同时被分开。 第三和第四存储器单元簇(MCC3,MCC4)连接到连接到第一和第二存储器单元簇的字线,并且在共享与位线对不同的位线对的同时被分开操作。 为了构成数据输入/输出路径,列通过门(84)响应于列选择信号将连接到四个存储器单元簇的位线对中的一个切换到公共读出放大器。

    • A method for manufacturing a semiconductor capacitor is provided to prevent the generation of short between adjacent lower electrodes by forming a spacer containing a metallic oxide at both upper sidewalls of each lower electrode. A mold layer with opening portions is formed on a semiconductor substrate(30). A lower electrode thin film is formed along an upper surface of the resultant structure. A sacrificial layer is formed thereon. A polishing process is performed on the resultant structure until the mold layer is exposed to the outside. An upper portion of the exposed mold layer is removed from the resultant structure to expose an upper sidewall of the lower electrode thin film. A thin film having a relatively high etch selectivity compared to the mold layer and sacrificial layer is formed. A spacer(72) is formed at both upper sidewalls of the lower electrode thin film by performing an etch back process on the resultant structure.
    • 提供一种制造半导体电容器的方法,以通过在每个下电极的两个上侧壁处形成包含金属氧化物的间隔来防止在相邻的下电极之间产生短路。 在半导体衬底(30)上形成具有开口部分的模制层。 沿所得结构的上表面形成下电极薄膜。 在其上形成牺牲层。 对所得到的结构进行抛光处理,直到模具层暴露于外部。 暴露的模制层的上部从所得结构中去除以暴露下部电极薄膜的上侧壁。 形成与模具层和牺牲层相比具有相对高的蚀刻选择性的薄膜。 通过对所得结构执行回蚀处理,在下电极薄膜的两个上侧壁处形成间隔物(72)。
