Via structure integrated in electronic substrate
A system of via structures disposed in a substrate. The system includes a first via structure that comprises an outer conductive layer, an inner insulating layer, and an inner conductive layer disposed in the substrate. The outer conductive layer separates the inner insulating layer and the substrate and the inner insulating layer separates the inner conductive layer and the outer conductive layer. A first signal of a first complementary pair passes through the inner conductive layer and a second signal of the first complementary pair passes through the outer conductive layer. In different embodiments, a method of forming a via structure in an electronic substrate is provided.
