Abstract:
A package for a semiconductor chip, in particular for CSP, &mgr;BGA or FBGA packages, with a carrier board made of polyimide, the carrier board having a central slot and being provided on one side with interconnects and a micro-ball grid array and on the other side, next to the slot, with a plurality of rows of nubbins for receiving the semiconductor chip by die bonding, and in which the bonding pads are arranged in a linear central manner on the semiconductor chip and are connected to the interconnects on the carrier board via contact bridges passed through the slot, characterized in that provided on the carrier board (1), on the side of the nubbins (8), is a frame (9) which directly surrounds the slot (5), is of the same height as the nubbins (8) and has, at least on the chip side, an adhesive bonding edge, and in that the slot (5) and the frame (9) surrounding the latter are at least partially filled with a casting compound.
