    • A method for fabricating a semiconductor memory device includes the consecutive steps of consecutively depositing metallic, nitride and oxide films on an underlying insulating film, patterning the nitride and oxide films to allow the oxide film to have a patterned area smaller than the patterned area of the nitride film, patterning the metallic film by using the nitride and oxide films as a mask, forming a side-wall film having a tapered mesa structure on the oxide, nitride and metallic films, embedding the side-wall oxide film by an interlayer dielectric film, and forming a contact hole in the interlayer dielectric film and the underlying oxide film while using the side-wall oxide film as an etch stopper.
    • 一种用于制造半导体存储器件的方法包括在下面的绝缘膜上连续沉积金属,氮化物和氧化物膜的连续步骤,对氮化物和氧化物膜进行图形化,以使氧化物膜具有比图案化区域小 氮化物膜,通过使用氮化物和氧化物膜作为掩模对金属膜进行构图,在氧化物,氮化物和金属膜上形成具有锥形台面结构的侧壁膜,通过层间绝缘膜包埋侧壁氧化膜 并且在使用侧壁氧化物膜作为蚀刻停止层的同时在层间电介质膜和下面的氧化物膜中形成接触孔。

    • A road information generating apparatus has a stored digitized map database having data identifying roads on a route. The roads of the map database are stored as road segments each having endpoints. The apparatus cancels data defining selected road segments that fall outside of a predetermined window about a predetermined circle approximating a predetermined road curve. The apparatus determines circles each approximating a portion of unselected road segments. The apparatus compares a radius of each of the circles with a predetermined radius value. The apparatus produces road information on acute curve in response to result of comparing the radius of each curve with the predetermined radius value.
    • 道路信息生成装置具有存储的数字化地图数据库,其具有识别路线上的道路的数据。 地图数据库的道路被存储为各自具有端点的路段。 该装置取消定义围绕预定的绕近预定道路曲线的预定圆落在预定窗口之外的所选道路段的数据。 该装置确定每个近似未选路段的一部分的圆。 该装置将每个圆的半径与预定的半径值进行比较。 响应于将每个曲线的半径与预定的半径值进行比较的结果,该装置产生急性曲线上的道路信息。
