Classification: CPC H | IPC H

Claim 6:
7. A method of manufacturing a semiconductor package, comprising:
providing a first magnetic member;
positioning a first build-up film abutting the first magnetic member;
positioning a laminate member abutting the first build-up film, the laminate member containing primary and secondary transformer windings;
positioning a second build-up film abutting the laminate member;
positioning a second magnetic member abutting the second build-up film;
melting the first build-up film and the second build-up film;
causing the first magnetic member and the second magnetic member to be in contact with each other to form a transformer device;
mounting the transformer device on a lead frame surface; and
covering the transformer device and the lead frame surface in a molding to produce a semiconductor package.
