Abstract

Multichip module thermal management through backside metal systems and methods are disclosed. In one aspect, a multichip module includes one or more flip chip integrated circuits (ICs), each having a backside to which a metal heat conductor or spreader is attached. The presence of the metal heat conductor on the backside of the flip chip ICs allows for a better thermal path to remove heat from the ICs relative to the substrate. The improved thermal path reduces the likelihood of damage to the ICs or delamination of the module. A variety of methods are proposed to construct the backside metal systems. Additionally, a variety of capture features may be used to assist in structural integrity.
