Abstract:
A method to produce a nanowired interconnection is presented. This bonding method for power die, provides elasticity to the assembly while offering a good electrical and thermal path compared to the established laser microvias. Experimental results demonstrate a well-distributed nanowire growth at the surface, which leads to a bond with a heat extraction and a current conduction similar to existing die attachment solutions, such as silver sintering.
