Patent ID: 7994633

Claim:
A substrate for electrical device, comprising: at least a first conductive element having at least a first upper surface, a first lower surface, a first side edge and a protruding portion; at least an insulator having at least a first upper surface, a first lower surface and a side wall, said first conductive element encapsulated by said insulator and embedded therein, in this manner, said first side edge of said first conductive element being encapsulated by said insulator, wherein said protruding portion of said first conductive element being protruded and exposed to the first lower surface of said insulator, in this manner, said first lower surface of said first conductive element being protruded and exposed to the first lower surface of said insulator too; and wherein said first upper surface of said first conductive element exposed to said first upper surface of said insulator for being plated by at least a conductive material, wherein said first upper surface of said first conductive element being below said first upper surface of said insulator, therefore, at least a recess formed by said first conductive element associated with said insulator, wherein the bottom of said recess formed by said first upper surface of said first conductive element, and wherein said recess being for accommodating at least a conductive material; and at least a conductive material, wherein said first upper surface of said conductive element being plated by said conductive material, and wherein at least a portion of said conductive material being placed within said recess, and wherein at least an another portion of said conductive material exposed to said first upper surface of said insulator.
