Patent ID: 8829356

Claim:
A packaging substrate having a passive element embedded therein, comprising: a dielectric layer unit having a top surface and a bottom surface; at least a positioning pad embedded in the bottom surface of the dielectric layer unit; at least a passive element embedded in the dielectric layer unit and corresponding in position to the at least a positioning pad, the at least a passive element having a plurality of electrode pads formed on one or both of an upper surface and an opposing lower surface of the at least a passive element; a first circuit layer formed on the top surface of the dielectric layer unit, and having a plurality of first conductive vias electrically connected to the electrode pads formed on the upper surface of the at least a passive element; and a second circuit layer formed on the bottom surface of the dielectric layer unit, and having a plurality of second conductive vias electrically connected to the electrode pads disposed on the lower surface of the at least a passive element, wherein the second conductive vias penetrate through the at least a positioning pad.
