Claim 0:
1. A substrate, comprising:
a first insulation layer having a top surface and a bottom surface;
at least one passive component embedded in the first insulation layer, wherein each passive component comprises a first conducting terminal;
at least one first through-hole structure formed in the first insulation layer and arranged beside a first side of the passive component, wherein the first through-hole structure runs through the first insulation layer, and the first through-hole structure comprises a conductive part and an insulation part, wherein the insulation part is disposed within the conductive part, and the conductive part of the first through-hole structure is in contact with the first conducting terminal and formed as a first electrode;
a second insulation layer disposed on portion of the conductive part of the first through-hole structure that is close to the bottom surface of the first insulation layer; and
a second electrode, wherein at least part of the second electrode is disposed on the second insulation layer, and the second electrode is in contact with the bottom surface of the first insulation layer,
wherein a projected area of the second electrode and a projected area of the first electrode along a direction perpendicular to the top surface of the first insulation layer are at least partially overlapped with each other, and the second electrode and the first electrode are different electrodes.
