Abstract: A design method and system for minimizing blind via current loops provides for improvement of electrical interconnect structure design without requiring extensive electromagnetic analysis. Other vias in the vicinity of a blind via carrying a critical signal are checked for suitability to conduct return current corresponding to the critical signal that is disrupted by the transition from a layer between two metal planes to another layer. The distance to the return current via(s) is checked and the design is adjusted to reduce the distance if the distance is greater than a specified threshold. If the blind via transition is to an external layer, suitable vias connect the reference plane at the internal end of the blind via to an external terminal. If the transition is between internal layers, suitable vias are vias that connect the two reference planes surrounding the reference plane traversed by the blind via.

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.
