Investigating the Sintering Process and Mechanical Properties of Nano-copper Particles Coupling Particle Packing Modeling with Molecular Dynamics Simulation

The nano-copper particles are widely used in the sintering processes of packaging wide bandgap semiconductors. Despite the significant success in the industry, the mechanism bridging the sintering process to the mechanical properties of sintered nano-copper is not yet well-modeled. In this paper, the impacts of different sintering temperatures...

High-temperature nanoindentation characterization of sintered nano-copper particles used in high power electronics packaging

Nano-copper sintering is one of new die-attachment and interconnection solutions to realize the wide bandgap semiconductor power electronics packaging with benefits on high temperature, low inductance, low thermal resistance and low cost. Aiming to assess the high-temperature reliability of sintered nano-copper die-attachment and...
