Abstract :
A novel low temperature bonding method for potential use in 3D integration is reported in this paper. Metallic (Ni and Cu) micro-cones arrays fabricated by one step electroplating were utilized to bond with solder bumps with appropriate temperature and pressure. The bonding strength of this unique architecture was evaluated by shear testing with results comparable to reflow soldering.
