Patent ID: 8378776

Claim:
A semiconductor structure comprising: a non-conductive structure; a transformer touching the non-conductive structure and having a first coil, a second coil spaced apart from the first coil, and a magnetic core structure that lies within the first and second coils, the first coil having a plurality of lower coil structures that lie in a first horizontal plane within the non-conductive structure and a plurality of upper coil structures that lie in a second horizontal plane within the non-conductive structure, the second horizontal plane lying above the first horizontal plane; a signal structure touching the non-conductive structure and having a pair of metal members, the pair of metal members being spaced apart, a first metal member of the pair of metal members lying in a horizontal plane that lies above the first horizontal plane, a second metal member of the pair of metal members lying in a horizontal plane that lies below the second horizontal plane; a first via member that touches and extends through the non-conductive structure to touch the first metal member; a second via member that touches and extends through the non-conductive structure to touch the second metal member; and a plurality of third via members that touch and extend through the non-conductive structure to touch the lower coil structures and the upper coil structures.
