Design for packageability-the impact of bonding technology on the size and layout of VLSI dies

The impact of bonding technology from an IC designer's point of view is studied. Work by others has concentrated just on the effect of packaging alone, whereas this study investigates the effect of changing the VLSI dies. Specifically, the impact of wire-bond and flip-chip technologies on the size and layout of VLSI dies is demonstrated by means of general discussion and detailed examples. Three VLSI chips of various sizes and I/O requirements have been synthesized based on a standard-cell library for both wire-bond and flip-chip. The results show different die layouts and sizes can be achieved based on the choice of wire-bond or flip-chip technologies.<>
