First Claim
1. A method for manufacturing a hermetically sealed multi-pane window assembly, the method comprising the following steps:
- providing a first windowpane sheet formed of a transparent material and having a periphery and a first sealing member having an inner edge and an outer edge;
positioning the inner edge of the first sealing member around the periphery of the first windowpane sheet;
pressing the inner edge of the first sealing member against the first windowpane sheet with sufficient force to produce a first predetermined contact pressure between the inner edge and the windowpane sheet along a first junction region;
heating the first junction region to produce a first predetermined temperature along the first junction region;
maintaining the first predetermined contact pressure and an elevated temperature until a diffusion bond is formed between the first sealing member and the first windowpane sheet around the periphery of the first windowpane sheet;
providing a second windowpane sheet formed of a transparent material and having a periphery and a second sealing member having an inner edge and an outer edge;
positioning the inner edge of the second sealing member around the periphery of the second windowpane sheet;
pressing the inner edge of the second sealing member against the second windowpane sheet with sufficient force to produce a second predetermined contact pressure between the inner edge and the windowpane sheet along a second junction region;
heating the second junction region to produce a second predetermined temperature along the second junction region;
maintaining the second predetermined contact pressure and an elevated temperature until a diffusion bond is formed between the second sealing member and the second windowpane sheet around the periphery of the second windowpane sheet; and
hermetically connecting the outer edge of the first sealing member to the outer edge of the second sealing member, whereby a hermetically sealed cavity is defined between the first and the second windowpanes.

Abstract
A method for manufacturing a hermetically sealed window assembly. A first windowpane is provided, as is a first sealing member having inner and outer edges. The inner edge is positioned against the windowpane and pressed against it with sufficient force to produce a first contact pressure along a first junction. The junction is heated to produce a first temperature. The contact pressure and temperature are maintained until a diffusion bond is formed between the member and the windowpane. A second windowpane is provided, as is a second sealing member having inner and outer edges. The inner edge is positioned against the windowpane and pressed against it with sufficient force to produce a second contact pressure along a second junction. The junction is heated to produce a second temperature. The contact pressure and temperature are maintained until a diffusion bond is formed between the member and the windowpane. A spacer assembly is positioned between the first and second windowpanes for maintaining a gap therebetween. The outer ends of the sealing members are hermetically connected to one another, whereby a hermetically sealed cavity is defined between the windowpanes.
