Claim 9:
10. The substrate according to claim 9, further comprising:
at least one second through-hole structure formed in the first insulation layer and arranged beside a second side of the passive component, wherein the second through-hole structure runs through the first insulation layer, and the second 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 second through-hole structure is in contact with the second conducting terminal and formed as a fourth electrode;
a third insulation layer disposed on portion of the conductive part of the second through-hole structure that is close to the top surface of the first insulation layer; and
a third electrode, wherein at least part of the third electrode is disposed on the third insulation layer, and the third electrode is in contact with the top surface of the first insulation layer,
wherein a projected area of the fourth electrode and a projected area of the third electrode along the direction perpendicular to the top surface of the first insulation layer are at least partially overlapped with each other, wherein the fourth electrode and the third electrode are different electrodes.
