Abstract
This communication reports on the microstructure and interdiffusion ob served in a new NbSn2/Nb metallization structure on SiO2, previously r eported [H. S. Chen et al., Appl. Phys. Lett. 66, 2191 (1995)]. The as -deposited NbSn2 layer was found to be amorphous. After heating, the N bSn2 becomes polycrystalline and heavily diffused with Au from the Au- Sn solder. The Nb layer remains pure and intact after heating. The mic rostructure, compositions, and phases of the Au-Sn solder layer are al so presented.
