Abstract
In a symmetric crossover structure of two lines formed of a lower conductor layer and a higher conductor layer above a substrate, each of the two lines is branched to two routes at where they are crossed over to each other. The first route of the first line uses the higher layer to cross the first route of the second line and the lower layer to cross over the second route of the second line. The second route of the first line uses the lower layer to cross over the first route of the second line and the higher layer to cross over the second route of the second line. The two lines therefore have symmetric coupling effects to the substrate.
