Claim of US Patent No. 10,251,280

1. An integrated circuit, comprising:a substrate;
a first dielectric layer above the substrate;
coil bottom leads positioned in the first dielectric layer;
a second dielectric layer on the first dielectric layer;
a magnetic core on the second dielectric layer and above the coil bottom leads;
a third dielectric layer on the second dielectric layer and the magnetic core;
coil top leads on the third dielectric layer and above the magnetic core;
coil side leads penetrating the first, second, and third dielectric layers and coupling the coil top leads to the coil bottom leads to form a coil winding around the magnetic core.
