Abstract

The present invention is directed to a process of forming a package for enclosing an electrical device wherein the enclosure contains a very low amount of oxygen and water vapor. The package includes a base and lid components bonded together by a sealing glass. The lid component contains a gettering alloy from which the oxide layer is removed prior to the final sealing of the package. The gettering alloy forms a refractory oxide layer under an oxide layer formed with the primary constituent of the alloy.
