Abstract:
There is disclosed the preparation of an electronic device comprising a gas discharge panel constructed out of two or more glass substrates, each substrate containing at least one array of electrodes. In one preferred embodiment, there is prepared a display/memory panel comprising a dielectric coating or layer applied over an array of electrodes. The panel preparation comprises firing and curing the electrode (with or without a dielectric coating) onto a glass substrate which is supported by a base plate which maintains its surface flatness and lubricity at the elevated firing and curing temperatures such that the relative flatness and smoothness of the glass substrate (and any dielectric coating fired thereon) are enhanced and the uniformity of the panel spacing is improved. The base plate is typically prepared from a refractory or ceramic-like material.
Abstract:
Provided are sealing glass compositions particularly useful for sealing together alumina ceramic components in microelectronic circuitry. The sealing glass compositions are crystallizable and comprise a devitrifiable solder glass admixed with (1) a refractory material and (2) a pre-crystallized glass which together are employed in an amount sufficient to substantially reduce the time necessary to effect in situ crystallization and at the same time form a strong hermetic seal. The sealing glass compositions may be employed in any conventional form and are fired at about 400*-500* C. for about one minute to less than about 60 minutes to form a seal as described.
