Claim 13:
14. A semiconductor package comprising: an insulating layer including an upper surface, and a lower surface opposite to the upper surface; a circuit layer positioned higher than the upper surface of the insulating layer with respect to the lower surface of the insulating layer; and a top metal layer disposed on the circuit layer, wherein the top metal layer includes a first portion that is vertically overlapped with the circuit layer, and a second portion that is not vertically overlapped with the circuit layer, wherein a lower surface of the first portion of the top metal layer is in direct physical contact with the circuit layer, and a lower surface of the second portion of the top metal layer does not contact the circuit layer, wherein the top metal layer is formed of gold or a gold alloy, and wherein the second portion of the top metal layer directly faces the insulating layer with no intervening elements therebetween; wherein the circuit layer includes a first layer and a second layer disposed on the first layer, wherein a thickness of the first layer is greater than a thickness of the second layer, and wherein the first layer and the second layer include a same metal material.
