Claim 0:
1. An electronic assembly, comprising:
a component comprising conductive studs over an active layer of the component, wherein each of the conductive studs comprises a first end directly connected to a contact pad coupled with the active layer and a second end opposite the first end wherein the second end is in a range of 2-50 micrometers (μm) from the first end;
a first layer of encapsulant disposed around four side surfaces of the component, over the active layer of the component, and contacting at least a portion of the sides of the conductive studs;
a substantially planar surface disposed over the active layer of the component, wherein the substantially planar surface comprises ends of the conductive studs and the first layer of encapsulant;
a first conductive layer and first conductive stumps disposed over the first layer of encapsulant and configured to be electrically coupled with the conductive studs of the component;
a second layer of encapsulant disposed over the first conductive layer and surrounding at least a portion of the first conductive stumps, wherein ends of the first conductive stumps are exposed with respect to the second layer of encapsulant;
a second conductive layer and second conductive stumps disposed over the second layer of encapsulant and configured to be electrically coupled with the first conductive layer and first conductive stumps;
a third layer of encapsulant disposed over the second conductive layer and surrounding at least a portion of the second conductive stumps, wherein ends of the second conductive stumps are exposed with respect to the third layer of encapsulant;
a conductive contact disposed over, or within, the third layer of encapsulant and configured to be electrically coupled to the component through one or more of the first conductive stump and the second conductive stumps;
wherein the first layer of encapsulant, the second layer of encapsulant, and the third layer of encapsulant comprise a surface roughness of less than 500 nanometers (nm) over a characteristic measurement distance;
wherein the first conductive layer and the second conductive layer comprise lower surfaces comprising corresponding surface roughness less than 500 nm over a characteristic measurement distance; and
wherein the first conductive stumps are formed of a single layer of material and at least a portion of the sidewalls of the first conductive stumps directly contact the second encapsulant.
