Patent ID: 8552642

Claim:
A package, comprising: a first glass substrate, a second glass substrate, a wall that separates the first and second substrates, said wall comprising a sintered glass frit having a width and a melting temperature Tfrit-melt, and at least one element that is sensitive to heat and at least one of oxygen and moisture and is hermetically sealed between the first and second substrates by the wall, said at least one element having a degradation temperature Tdegrade, wherein: (i) at least a portion of a width of the wall is laser sealed to the second substrate; (ii) a minimum width of the portion of the wall that is sealed to the second substrate at any location along the wall is Wseal-min, where Wseal-min is less than the width of the wall; (iii) a minimum distance between an edge of the at least one element and an edge of the portion of the wall that is sealed to the second substrate at any location along the wall is Lmin; and (iv) Wseal-min, Lmin, and Tfrit-melt satisfy the relationships: (a) Wseal-min≧2 mm; (b) 0.2 mm≦Lmin≦2.0 mm; and (c) Tfrit-melt≧6.0·Tdegrade.
