Abstract:
1. A substrate structure with bumps, comprising: a plurality of conductive elements; a first dielectric layer, having a first surface and a second surface opposite to the first surface, wherein the conductive elements are embedded in the first dielectric layer; a plurality of first circuits, disposed on the second surface of the first dielectric layer; a plurality of contacts, disposed on the second surface of the first dielectric layer and connected with the conductive elements; a second dielectric layer, disposed on the second surface of the first dielectric layer, wherein the second dielectric layer covers the first circuits and exposes the contacts; a plurality of second and third circuits, embedded in the first dielectric layer, wherein the second circuits are disposed on the third circuits, top surfaces of the second circuits are coplanar with the first surface of the first dielectric layer; a plurality of bumps, disposed on the top surfaces of a portion of the second circuits and electrically connected to the contacts through a number of the second and third circuits disposed between the conductive elements and the bumps, wherein the top surfaces of another portion of the second circuits are exposed and uncovered; and a metallic layer, disposed on the bumps and disposed on exposed surfaces of the contacts.
