Abstract:
1. A microelectronic assembly, comprising: a semiconductor chip having a face; a plurality of electrically conductive connectors upon the face of the semiconductor chip, each connector having a surface facing away from the face of the semiconductor chip; a plurality of compressible dielectric first regions contacting the surfaces of the connectors and surrounding the connectors in directions along the face of the semiconductor chip; a plurality of dielectric second regions surrounding the first regions, wherein the first regions are more compressible than the second regions, wherein at least portions of adjacent ones of the second regions are spaced apart from one another; a carrier having a contact-bearing face and a plurality of contacts exposed thereat, wherein the contact-bearing face of the carrier faces toward the connectors, and the contacts are electrically connected with the connectors, and; an underfill disposed between the faces of the chip and the carrier between adjacent ones of the second regions.
