Abstract: A low inductance via arrangement for multilayer ceramic (MLC) substrates is provided. With the MLC substrate and via arrangement of the illustrative embodiments, the via-field inductance for a given contact pad array is reduced. This reduction is achieved by the introduction of T-jogs and additional vias. These T-jogs and additional vias form additional current paths that cause additional parallel inductances that reduce the via-field inductance. In one illustrative embodiment, the additional T-jogs and vias are added to a center portion of a contact pad array. The T-jogs are comprised of two jogs in a wiring layer of the MLC, each jog being toward a via associated with an adjacent contact pad in the contact pad array. These additional T-jogs and vias form additional current loops parallel to the existing ones which thus, reduce the total inductance of the via-field.
