摘要 |
Embodiments of the invention are directed to a method comprising depositing a dielectric layer on a circuitized layer having a conductive region. The dielectric layer is preferably a bonding sheet. An aperture is formed in the dielectric layer over the conductive region. A conductive body, disposed on another circuitized substrate, is inserted into the aperture. The conductive body comprises a main region (e.g., a conductive post) and a depletion region (e.g., a thin layer of metal or transient liquid alloy bonding material). The depletion region contacts the conductive region on the circuitized layer, and the circuitized layers are laminated together. Heat and pressure can be applied to the combination in order to form an intermetallic region from the depletion region.
