  • Method of producing smooth metallic layers on a substrate
    Patent number: 4382977
    Abstract: Smooth layers of a metal are produced on a glass substrate where a large ferential expansion coefficient of the metal relative to the substrate produces very large stresses in the metal when the metallized substrate is subjected to a post deposition anneal. The method involves depositing a layer of a metal having a very small self diffusion coefficient at the anneal temperature prior to depositing the metal having the large differential expansion coefficient.
