Abstract

A new type of Ag nanoparticle (NP) paste for rapid sintering was prepared by controlling the thickness of the NP capping agent. The Ag NP paste was combined with a rapid thermo-compression (RTC) method to form a reliable Cu–Cu joint. The shear strengths of the Cu/Ag NP/Cu joints were 46.8 MPa and 90.7 MPa after sintering at 300 °C for only 5 s and 20 s, respectively. The sintering sequence phenomenon was observed, and the differences in microstructure between the pressure-assisted and pressureless joints were investigated. Robust bonding at the lattice level between the Ag NPs and Cu substrate was observed by high-resolution transmission electron microscopy, and this bonding contributed to the high shear strength obtained under rapid sintering conditions. A commercially acceptable alternative solution to achieving reliable Cu–Cu joint formation was obtained, especially for thermo-sensitive devices.
