Abstract:
1. An embedded trace substrate comprising: a dielectric layer; at least one bias trace comprising a first bias trace and a second bias trace, the at least one bias trace being embedded in the dielectric layer such that the at least one bias trace extends an at least one bias trace depth into the dielectric layer; at least one signal trace horizontally positioned along a dielectric layer first surface between the first bias trace and the second bias trace, the at least one signal trace being embedded in the dielectric layer such that the at least one signal trace extends an at least one signal trace depth into the dielectric layer, wherein the at least one bias trace depth is greater than the at least one signal trace depth; and wherein: the at least one signal trace comprises a first signal trace and a second signal trace, further wherein; the first signal trace and the second signal trace are horizontally positioned along the dielectric layer first surface between the first bias trace and the second bias trace.
