    • Embodiments relate to a method of forming a polysilicon pattern, which may be able to form a minute pattern. In embodiments, the method may in clued forming a first polysilicon pattern by selectively etching a polysilicon layer using a photoresist pattern at a fixed interval, forming an oxide layer having a concavo-convex pattern in the first polysilicon pattern, so as to form a second polysilicon pattern covered with the oxide layer, grinding the oxide layer in such an extent that exposes the upper surface of the second polysilicon pattern, etching the second polysilicon pattern exposed in state of using the oxide layer as a mask, forming an oxide-layer pattern used for a mask of a final polysilicon pattern being completed, by etching the oxide layer to a predetermined depth, and forming the final polysilicon pattern by selectively etching the polysilicon layer in state the oxide-layer pattern is used as a mask.
    • 实施例涉及形成多晶硅图案的方法,其可能能够形成微小图案。 在实施例中,该方法可以通过以固定的间隔选择性地使用光致抗蚀剂图案蚀刻多晶硅层来形成第一多晶硅图案,形成在第一多晶硅图案中具有凹凸图案的氧化物层,以形成第二多晶硅图案 用氧化物层覆盖的多晶硅图案,在暴露第二多晶硅图案的上表面的程度上研磨氧化物层,蚀刻在使用氧化物层作为掩模的状态下暴露的第二多晶硅图案,形成氧化物层图案 用于通过将氧化物层蚀刻到预定深度来完成最终多晶硅图案的掩模,并且通过在氧化物层图案用作掩模的状态下选择性地蚀刻多晶硅层来形成最终的多晶硅图案。

    • A cellular telephone with a voice dialing function effectively manages a voice recognition memory. The cellular telephone is capable of being connected to a hands-free kit, and has a voice recognition device for extracting feature data from an input voice signal so as to recognize the voice signal and a memory for storing the extended feature data. The memory is divided into a first storage area for storing the feature data input from the cellular telephone, a second storage area for storing the feature data input from the hands-free kit, and a third storage area for storing voice playback data. The third storage area includes a storage region for storing the voice playback data and another storage region for storing a telephone number associated with the voice playback data.
    • 具有语音拨号功能的蜂窝电话有效地管理语音识别存储器。 蜂窝电话能够连接到免提套件,并具有用于从输入语音信号中提取特征数据以识别语音信号的语音识别装置和用于存储扩展特征数据的存储器。 存储器被分成用于存储从蜂窝电话输入的特征数据的第一存储区域,用于存储从免提工具箱输入的特征数据的第二存储区域和用于存储语音播放数据的第三存储区域。 第三存储区域包括用于存储语音播放数据的存储区域和用于存储与语音播放数据相关联的电话号码的另一个存储区域。
