Patent ID: 8822276

Claim:
A method of bonding at least one chip to an external electrical circuit in forming an electrical device, the method comprising: etching the external electrical circuit to form conductive printed circuit pattern on a carrier, wherein the carrier comprises a ground plate disposed on a surface opposite from the external electrical circuit; forming conductive physical extensions from conductors of the external electrical circuit for connection to the at least one chip, wherein the forming of the conductive physical extensions comprising: forming electrical circuit openings on the ground plate at locations corresponding to those of the conductor physical extensions; and laser cutting carrier material covered by the conductive physical extensions through the electric circuit openings in order to remove the carrier material directly beneath the conductive physical extensions; removing material of the carrier within a predetermined area of the carrier in order to form a cavity such that the conductive physical extensions extend into the cavity; positioning the at least one chip into the cavity; and directly bonding the at least one chip to the conductive physical extensions.
