Abstract

A method of fabricating a high vacuum device by providing two major, parallel spaced apart glass sides in a substantial vacuum, forming a continuous edge between the sides and forming a tack with a metallic diffusion bond between the sides. The metallic diffusion bond is formed of materials that bond and cure faster than the material of the continuous edge so that the tack holds the sides in a fixed position while the continuous edge is curing.
