Abstract
An electronic package and method of making same in which a thermally conductive member is in thermally conductive communication with a semiconductor chip encapsulated within a dielectric material that surrounds portions of a thermally conductive member, semiconductor chip, and a predefined portion of a circuitized substrate. The present invention's thermally conductive member includes two portions of different bending stiffness to assure reduced interfacial stresses between the semiconductor chip and the circuitized substrate.
