Abstract

A semiconductor chip is shown containing an integral heat spreading layer that more effectively transmits heat from the die to ambient as a result of spreading the heat out on the die over a larger cross sectional area. Local hot spots are minimized which allows the semiconductor chip to operate at a higher frequency for a given upper threshold temperature. Also shown is a method of manufacturing such a semiconductor chip, and the associated method of cooling a semiconductor chip.
