Vertically packaged integrated circuit

摘要

A device comprises a semiconductor package including a first integrated circuit (IC) die including a plurality of through silicon vias (TSVs). The TSVs are formed of conductive material that extend through the first IC die from an outer surface on a first side of the die to an outer surface of a second side of the die. The package further includes first electrical connections contacting the first side of the first IC die, and second electrical connections contacting the second side of the first IC die. The first electrical connections are independent of the second electrical connections. Molding compound encapsulates the first IC die and the first and second electrical connections. The semiconductor package is mounted on a substrate so that the first and second sides of the IC die are oriented perpendicular to the substrate.
