Abstract :
A bonding method using single-micrometer bumps, which were formed by Ag nanoparticle, had been realized under low bonding temperature and low compressive stress. The bump diameter is 8 μm and the pitch is 16 μm. The bonding temperature was 250°C under compressive stress of about 41.4 MPa. A shear test was carried out and the strength of the bond could reach 5.89 MPa.
