In this paper, the application of gold-indium isothermal solidification technique in die attachment for ceramic packages is investigated. With a simple design of the multilayer system and mechanical vibration, silicon chip can be bonded onto the allumina substrate within 15 seconds between 250 oC and 300 oC in nitrogen atmosphere. Most of the samples can satisfy the shear strength test specified by MIL STD 883D. The reliability of the bonds is e valuated with thermal cycle test, and 1750 cycles test between...
