Abstract: A packaged integrated circuit (IC) includes a package substrate, an electronic device on the package substrate, and metal interconnects coupled between the electronic device and the package substrate. The packaged IC also includes an insulation material on the package substrate and encapsulating the electronic device. The insulation material surrounds the metal interconnects. An inductor is over the electronic device and is coupled to the package substrate. A magnetic material is on the insulation material and encapsulates the inductor. The magnetic material is different from the insulation material.

Abstract: An apparatus includes a laminate, the laminate including a dielectric layer having a first surface and a second surface opposed to the first surface, and a conductive layer forming a circuit element overlying the first surface of the dielectric layer. The apparatus further includes a magnetic layer over the conductive layer. A first edge surface of the magnetic layer is coplanar with a first edge surface of the laminate, and a second edge surface of the magnetic layer is coplanar with a second edge surface of the laminate.

Abstract: A laminate embedded core and coil structure comprises a magnetic core embedded in a laminate structure that includes two types of laminates. A first laminate embeds the coils of the structure and a second laminate fills space between the magnetic core and the first laminate, as well as space below the magnetic core and lower surface of the first laminate. The first and second laminates form a laminate structure that protects and improves isolation of the magnetic components. Solder resist encloses the laminate structure, magnetic core and coils. The laminate embedded core and coil structure may be assembled on a transformer leadframe of various types using non-conductive paste.

Abstract: In examples, a method of manufacturing a transformer device comprises providing a first magnetic member and providing a laminate member containing primary and secondary transformer windings wound around an orifice extending through the laminate member. The method further comprises positioning a build up film abutting the laminate member. The method also comprises positioning at least a portion of a second magnetic member in the orifice. The method further comprises heat pressing at least one of the first and second magnetic members such that a distance between the first and second magnetic members decreases and such that the build-up film melts, thereby producing a transformer device.
