Patent ID: 7259464

Claim:
An interconnection array subunit, comprising: a first pair of line conductors in first and second regions, said first pair of line conductors including a first true line conductor and a first associated complementary line conductor connected and vertically twisted in a vertical twisting region between said first and second regions; a second pair of line conductors adjacent to said first pair of line conductors in said first and second regions, said second pair of line conductors including a second true line conductor and a second associated complementary line conductor; a first interconnection layer disposed in said vertical twisting region, said first interconnection layer connecting said second associated complementary line conductor in said first region to said second associated complementary line conductor in said second region; and a second interconnection layer disposed in said vertical twisting region, said second interconnection layer connecting said second true line conductor in said first region to said second true line conductor in said second region; wherein said first true line conductor is disposed below said first associated complementary line conductor in said first region and above said first associated complementary line conductor in said second region, and said second true line conductor is disposed below said second associated complementary line conductor in said first and second regions, wherein said first interconnection layer and said second interconnection layer are disposed below said first of line conductors in said vertical twisting region.
