Self-densifying interconnection between a high-temperature semiconductor device selected from GaN or SiC and a substrate
A self-densifying interconnection is formed between a high-temperature semiconductor device selected from a GaN or SiC-based device and a substrate. The interconnection includes a matrix of micron-sized silver particles in an amount from approximately 10 to 60 weight percent; the micron-sized silver particles having a particle size ranging from approximately 0.1 microns to 15 microns. Bonding particles are used to chemically bind the matrix of micron-sized silver particles. The bonding particles are core silver nanoparticles with in-situ formed surface silver nanoparticles chemically bound to the surface of the core silver nanoparticles and, at the same time, chemically bound to the matrix of micron-sized silver particles. The bonding particles have a core particle size ranging from approximately 10 to approximately 100 nanometers while the in-situ formed surface silver nanoparticles have a particle size of approximately 3-9 nanometers.
