    • A method for forming a device is disclosed. The method includes providing a substrate prepared with first and second contact regions and a dielectric layer over the contact region. First and second vias are formed in the dielectric layer. The first via is in communication with the first contact region and the second via is in communication with the second contact region. A buried void provides a communication path between the first and second vias. The vias and buried void are at least partially filled with a dielectric filler. The partially filled buried void blocks the communication path between the first and second vias created by the buried void. The dielectric filler in the vias is removed, leaving remaining dielectric filler in the buried void to block the communication path between the first and second vias and contact plugs are formed in the vias.
    • 公开了一种用于形成装置的方法。 该方法包括提供用第一和第二接触区域制备的衬底和在接触区域上的电介质层。 第一和第二通孔形成在电介质层中。 第一通孔与第一接触区域连通,第二通孔与第二接触区域连通。 埋置的空隙提供第一和第二通孔之间的连通路径。 通孔和掩埋的空隙至少部分地填充有介电填料。 部分填充的掩埋空隙阻挡由埋入空隙产生的第一和第二通孔之间的连通路径。 去除通孔中的介电填料,留下掩埋空隙中的剩余电介质填料阻止第一和第二通孔之间的连通路径,并且在通孔中形成接触塞。
