Patent ID: 7067859

Claim:
A bus layout design comprising: a first electrically conductive layer including at least a first bus and a second bus, a second electrically conductive layer including at least a first bus and a second bus, an electrically insulating layer disposed between the first electrically conductive layer and the second electrically conductive laser, a plurality of vias through said electrically insulating layer conductively connecting said first electrically conductive layer and said second electrically conductive layer and arranged such that said first bus and said second bus of said first electrically conductive layer are electrically connected; and wherein said first and second electrically conductive layers and said vias are configured such that said second bus of said first electrically conductive layer is ultimately electrically connected to said first bus of said second electrically conductive layer yet said vias do not extend from said second bus of said first electrically conductive layer to said first bus of said second electrically conductive layer, wherein said plurality of vias connecting said first electrically conductive layer and said second electrically conductive layer are arranged such that said first bus and said second bus of said second electrically conductive layer are electrically connected.
