Redundant micro-loop structure for use in an integrated circuit physical design process and method of forming the same
摘要：
An integrated circuit including a first wire of a first level of wiring tracks, a second wire of a second level of wiring tracks, a third wire of a third level of wiring tracks, and a fourth wire located a first distance from the second wire in the second level of wiring tracks. A first via connects the first and second wires at a first location of the second wire. A second via connects the second and third wires at the first location, the second via is substantially axially aligned with the first via. A third via connecting the third and fourth wires at a second location of the fourth wire. A fourth via connecting the first and fourth wires at the second location, the fourth via is substantially axially aligned with the third via. The second, third, and fourth vias, and the third and Fourth wires form a path between the first and second wires redundant to the first via.
摘要（中）：

一种集成电路，包括第一级布线轨道的第一线，第二级布线轨道的第二线，第三级布线轨道的第三线和与第二线的第一距离的第四线 第二层线路。 第一通孔在第二导线的第一位置连接第一和第二导线。 第二通孔在第一位置处连接第二和第三导线，第二通孔基本上与第一通孔轴向对准。 第三通过在第四线的第二位置连接第三和第四导线。 第四通孔在第二位置处连接第一和第四导线，第四通孔基本上与第三通孔轴向对准。 第二，第三和第四通孔以及第三和第四导线形成第一和第二导线之间的路径，该路径对于第一通孔是冗余的。
