Abstract
Extraordinary adhesion of a Nb-based/Au-Sn metallization structure on a SiO2/Si substrate has been observed by a tensile pull test. The meta llization bond fails mostly via fracture through either the Si substra te or epoxy adhesive. The intrinsic adhesion pull strength of the meta llization scheme is concluded to be greater than 10 kpsi, and the adhe sion exceeds the Si-Si cohesive strength. The Nb-Si and Nb-O bonds at the interface are thermodynamically stable.
