Certain example embodiments of this invention relate to vacuum insulating glass (VIG) units having improved seals made using two different frit-based edge seal materials, and/or methods of making the same. In certain example embodiments, a first frit material is applied around peripheral edges of first and second glass substrates. The first frit material, which may be bismuth-based in certain example embodiments, is fired with a heat treatment (e.g., thermal tempering) process. A second frit material, which may be VBZ-based in certain example embodiments, is applied and at least partially overlaps with the fired first frit material. The first frit material acts as a primer, and the second frit material helps seal together the VIG unit. The second frit material is fired at a significantly lower temperature that enables the glass to retain the temper or other strength imparted by the heat treatment.

A method of producing a hermetic package includes forming a first sealing material layer on a first glass substrate, and arranging a frame body having an opening on its top so that a bottom portion of the frame body and the first sealing material layer are in contact, followed by sealing the frame body and the first glass substrate with each other via the first sealing material layer. The method further includes forming a second sealing material layer on an upper edge portion of the frame body, housing, in the frame body, a member, and arranging a second glass substrate to be in contact with the second sealing material layer, followed by sealing the second glass substrate and the frame body with each other via the second sealing material layer by irradiating the second sealing material layer with laser light from a second glass substrate side.
