Abstract: A thermal interface material, an integrated circuit formed therewith, and a method of application thereof are provided. The thermal interface material includes 5% to 30% by volume of a polymer component and at least 70% by volume of liquid metal droplets, all based on total volume of the thermal interface material. The polymer component has a first polymer having a molecular weight in a range of 400 g/mol to 400,000 g/mol. The liquid metal droplets are dispersed throughout the polymer component.

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.
