Abstract
A die of an integrated circuit and an upper layer of a circuit assembly are thermally connected by applying a thermal interface material (TIM) on the die, such that the TIM is between the die and an upper layer. The TIM comprises an emulsion of liquid metal droplets and uncured polymer. The method further comprises compressing the circuit assembly thereby deforming the liquid metal droplets and curing the thermal interface material thereby forming the circuit assembly.
