Abstract:
1. A circuit, comprising: a first circuit area configured to operate based on a first voltage level; and a second circuit area configured to operate based on a second voltage level that is greater than the first voltage level; a plurality of patterned metal layers configured to interconnect one or more circuit elements of the first circuit area and the second circuit area, wherein the plurality of patterned metal layers are separated from each other by a corresponding dielectric layer, and wherein each patterned metal layer and corresponding dielectric layer is dimensioned for operation at the first voltage level; and one or more vias interconnected between one or more portions of the plurality of patterned metal layers that correspond to the second circuit area, wherein the one or more portions and the one or more vias form one or more interconnects for the second circuit area that are suitable for operating at the second voltage level.
