Patent ID: 7129575

Claim:
A semiconductor chip assembly, comprising: a semiconductor chip that includes first and second opposing surfaces, wherein the first surface of the chip includes a conductive pad; a conductive trace that includes a routing line, a bumped terminal and a metal pillar, wherein the bumped terminal includes a cavity; a connection joint that electrically connects the routing line and the pad; and an encapsulant that includes first and second opposing surfaces, wherein the first surface of encapsulant faces in a first direction, the second surface of the encapsulant faces in a second direction opposite the first direction, the chip is embedded in the encapsulant, the routing line extends laterally beyond the bumped terminal and the metal pillar and extends vertically beyond the chip in the second direction, the bumped terminal is contiguous with and integral with the routing line and extends vertically beyond the routing line in the second direction, the cavity faces in the first direction, extends into the bumped terminal and the metal pillar, is adjacent to the bumped terminal and spaced from the metal pillar and is covered by the bumped terminal and the metal pillar in the second direction, the metal pillar contacts and is non-integral with the routing line and the bumped terminal, does not cover the routing line in the second direction, covers the bumped terminal in the second direction and extends vertically beyond the routing line and the bumped terminal in the second direction, and the bumped terminal and the metal pillar are not covered in the second direction by the encapsulant or any other insulative material of the assembly.
