Abstract
An IC structure includes first, second, third and fourth transistors on a substrate, and first and second metallization layers over the transistors. The first metallization layer has a plurality of first metal lines extending laterally along a first direction and having a first line width measured in a second direction. One or more of the first metal lines are part of a first net electrically connecting the first and second transistors. The second metallization layer has a plurality of second metal lines extending laterally along the second direction and having a second line width measured in the first direction and less than the first line width. One or more of the second metal lines are part of a second net electrically connecting the third and fourth transistors, and a total length of the second net is less than a total length of the first net.
