Patent ID: 7011988

Claim:
A build up on die method utilizing multi-angle vias, the multi-angle vias being oriented at 1 degree to 179 degree in reference to the plane of the die, the method comprising: receiving a substrate material, the substrate material comprised of a plurality of cavities; tack-bonding at least one component into at least one cavity; placing at least one via on an active site of the at least one component; depositing a dielectric over at least the at least one component and the at least one via to form a dielectric layer; forming at least one channel in the dielectric layer to expose the at least one via; depositing a conductive surface over the dielectric layer and the exposed at least one via to form a conductive layer; etching the conductive layer to form a first circuitry layer; placing a least one solder bump on the first circuitry layer, the at least one solder bump having a known average height, wherein each solder bump is positioned substantially above each of the at least one vias; and, placing solder mask over the first circuitry layer, wherein the solder mask depth is less than the known average solder bump height.
