Patent ID: 7993983

Claim:
A method of making a semiconductor chip assembly, comprising: providing a routing line; then mechanically attaching a semiconductor chip to the routing line, wherein the chip includes first and second opposing surfaces, and the first surface of the chip includes a conductive pad; forming a connection joint that electrically connects the routing line and the pad; forming an encapsulant after attaching the chip to the routing line, wherein the encapsulant includes first and second opposing surfaces, the first surface of the encapsulant and the second surface of the chip face in a first direction, the second surface of the encapsulant and the first surface of the chip face in a second direction opposite the first direction, the encapsulant contacts and covers and extends vertically beyond the chip in the first direction, and the chip is embedded in the encapsulant and extends vertically beyond the routing line in the first direction; and grinding the encapsulant without grinding the chip such that the first surface of the encapsulant migrates in the second direction, and then grinding the encapsulant and the chip such that the first surface of the encapsulant and the second surface of the chip migrate in the second direction and are laterally aligned.
