HEAT SINK WITH PREATTACHED THERMAL INTERFACE MATERIAL AND METHOD OF MAKING SAME

摘要

A process of making an integrated heat spreader is disclosed. The integrated heat spreader is stamped with a thermal interface material under conditions to form a diffusion bonding zone between the integrated heat spreader and the thermal interface material. The thermal interface material can have one of several cross-sectional profiles to facilitate reflow thereof against a die during a method of assembling a packaged microelectronic device. The thermal interface material can also have one of several footprints to further facilitate reflow thereof against the die.
