The flat rail structure located in the adjacent metal layer.

摘要

The first metal layer of semiconductor Dips consists of a plural metal line extended by the first axis, and a first rail structure extended by the first line.The first rail structure is physically separated from the first metal line.The second metal layer is located on the first metal layer.The second metal layer includes the second line directly crossed on the first axis, the second metal line and the second line extended respectively, and the second rail structure extended.The second rail structure is physically separated from the second metal line.The second rail structure is located on the first rail structure.The revenge Biya lies between the first and second metal layers.Vivian serves three people to connect the first track structure to the second track structure.
