Abstract:
1. 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; mechanically attaching and electrically connecting a metal particle to the routing line after providing the metal particle; forming an encapsulant after attaching the chip and the metal particle to the routing line, wherein the encapsulant includes a first surface that faces in a first direction and a second surface that faces in a second direction opposite the first direction, the encapsulant covers the chip and extends vertically beyond the chip and the routing line in the first direction, the chip and the metal particle are embedded in the encapsulant and extend vertically beyond the routing line in the first direction, the routing line extends laterally beyond the metal particle towards the chip, and the metal particle is disposed outside a periphery of the chip and overlaps the routing line; exposing the first surface of the encapsulant; forming a connection joint that electrically connects the routing line and the pad; and providing a conductive trace that includes the routing line and the metal particle and is electrically connected to the pad and exposed within a periphery of the metal particle in the first direction after forming the encapsulant and the connection joint.
