Patent ID: 8368173

Claim:
A method for making a semiconductor package, comprising the steps of: (a) providing a base material, wherein the base material comprises at least one outer groove and at least one conductive via structure, the conductive via structure is disposed in the outer groove, and the conductive via structure comprises an outer insulation layer disposed on the outer groove and defining a first central groove, a conductor disposed on the first central groove and defining a second central groove, and an inner insulation layer filling the second central groove; (b) forming a first metal layer on the base material, wherein the first metal layer comprises a first inductor and a first lower electrode; (c) forming a first dielectric layer and a first upper electrode on the first lower electrode, wherein the first dielectric layer is disposed between the first upper electrode and the first lower electrode, and the first upper electrode, the first dielectric layer and the first lower electrode form a first capacitor; and (d) forming a first protective layer, so as to encapsulate the first inductor and the first capacitor.
