Substrate 100 may contain active devices, such field effect transistor (FETs) and diodes, and may contain passive devices such as resistors and capacitors that are wired into circuits using wires, such as wires 125A, 125B, 125C and 145, and vias 140 in first and second dielectric layers 105 and 115 as well as contacts (not shown) connecting devices (not shown) in the substrate and wires (such as d
