Patent ID: 7453140

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 and a filler; a connection joint that electrically connects the routing line and the pad; an insulative base that includes an aperture; 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 contacts the filler within a periphery of the aperture, extends laterally beyond the filler, extends vertically beyond the filler in the first direction where the routing line contacts the filler and extends vertically beyond the chip in the second direction; the filler contacts the insulative base in the aperture and extends vertically beyond the routing line in the second direction; the insulative base contacts the routing line, is overlapped by the chip and extends vertically beyond the chip, the routing line and the encapsulant in the second direction; the aperture extends through the insulative base in the first and second directions, extends vertically beyond the routing line in the second direction, does not extend vertically beyond the routing line in the first direction and has a diameter that decreases as the aperture extends in the second direction; the filler and the aperture are not covered in the second direction by the encapsulant, the insulative base or any other insulative material of the assembly; the filler, the aperture and the insulative base are laterally aligned with one another at a lateral surface that faces in the second direction; the insulative base surrounds and is adjacent to the filler at the lateral surface; the insulative base surrounds only the filler at the lateral surface where the insulative base is adjacent to the filler at the lateral surface; and the assembly is devoid of a printed circuit board.
