Claim 10:
11. A manufacturing method, comprising:
providing a substrate;
forming a first insulation layer on the substrate, wherein the first insulation layer has an upper surface, a lower surface opposite to the upper surface and a first through hole extending to the lower surface from the upper surface;
forming a conductive pad on the substrate through the first through hole, wherein the conductive pad fills the first through hole and protrudes relative to an opening of the first through hole;
forming a second insulation layer having a first surface and a second through hole, wherein the second through hole extends to the conductive pad from the first surface, wherein the entirety of the first surface is in the same level; and
forming a conductive trace having a second surface and connected to the conductive pad through the second through hole, wherein the entirety of the second surface is in the same level.
