Abstract

A semiconductor die includes a first set of metal lines and a second set of metal lines. The first set of metal lines and the second set of metal lines are placed in alternate planes and are orthogonal to each other. A via is used to connect a first metal line from the first set of metal lines with a second metal line from the second set of metal lines. The via location is offset such that a side of the first metal line is aligned with a side of the second metal line. Consequently, a metal line adjacent to the first metal line does not need to detour around the via.

Claims (9)

1. A semiconductor die, comprising:

a first metal layer having a first set of parallel metal lines that have a first predetermined width and spaced from each other at a first predetermined pitch;

a second metal layer having a second set of parallel metal lines with a second predetermined width, and spaced from each other at a second predetermined pitch, wherein the first and second sets of metal lines are orthogonal to each other and lie in alternate planes; and

a metal via that connects a first metal line of the first set of metal lines with a second metal line of the second set of metal lines, wherein the via is placed such that at least one side of the first metal line is aligned with at least one side of the second metal line so that at least one of the metal lines of the first set of metal lines adjacent to the first metal line does not detour around the via in order to maintain the first predetermined pitch.

2. The semiconductor die of claim 1 , wherein the second predetermined width of the second set of metal lines is greater than the first predetermined width of the first set of metal lines.

3. The semiconductor die of claim 1 , wherein each of the first metal line and the second metal line is used for signal routing.

4. The semiconductor die of claim 1 , wherein each of the first metal line and the second metal line is used for power routing.

5. The semiconductor die of claim 1 , wherein each of the first metal line and the second metal line is used for clock routing.

6. The semiconductor die of claim 1 , wherein the via is a cuboid.
