An SIP module includes a plurality of electrical components mounted to an interconnect substrate. The electrical components and interconnect substrate are covered by an encapsulant. A conductive post is formed through the encapsulant. A plurality of openings is formed in the encapsulant by laser in a form of a circuit pattern. A conductive material is deposited over a surface of the encapsulant and into the openings to form an electrical circuit pattern. A portion of the conductive material is removed by a grinder to expose the electrical circuit pattern. The grinding operation planarizes the surface of the encapsulant and the electrical circuit pattern. The electrical circuit pattern can be a trace, contact pad, RDL, or other interconnect structure. The electrical circuit pattern can also be a shielding layer or antenna. An electrical component is disposed over the SIP module and electrical circuit pattern.
