Abstract
A semiconductor device comprising at least one semiconductor chip, the or each semiconductor chip having a plurality of chip bonding pads, a package which encloses the at least one semiconductor chip, a first level interconnect comprising a printed circuit which overlies the at least one semiconductor chip in the package and extends externaly of the package to provide a plurality of outer leads, and a second level interconnect comprising means for electrically connecting the chip bonding pads to selected contacts on the printed circuit, which contacts overlie the at least one semiconductor chip. The invention also relates to a method of manufacturing such a semiconductor device and to a method of assembling a semiconductor assembly.
