Abstract:
1. A semiconductor device, comprising: a workpiece; a first conductive layer disposed over the workpiece, a first continuous portion of a first inductor and a first continuous portion of a second inductor being disposed within the first conductive layer, the first continuous portion of the second inductor, including connection structures, being symmetric to the first continuous portion of the first inductor, including connection structure, said first continuous portion of said first inductor being the only portion of said first inductor in said first conductive layer and said first continuous portion of said second inductor being the only portion of said second inductor in said first conductive layer; at least one second conductive layer disposed proximate the first conductive layer, a second portion of the first inductor and a second portion of the second inductor being disposed within said at least one second conductive layer, each second portion of the second inductor being symmetric to each second portion of the first inductor within each at least one second conductive layer; at least one first inductor via coupling the first continuous portion of the first inductor in the first conductive layer to the second portion of the first inductor in an adjacent second conductive layer; and at least one second inductor via coupling the first continuous portion of the second inductor in the first conductive layer to the second portion of the second inductor in the adjacent second conductive layer, wherein the at least one second inductor via is symmetric to the at least one first inductor via.
