ABSTRACT:
An article according to the invention comprises two bodies that are joined together by means of a compression bond, such as to form an enclosure. One of the bodies comprises a (exemplarily Au-covered) textured surface region, and the other body comprises a (exemplarily Au) "O-ring" positioned such as to mate with the textured region, substantially surrounding the enclosure. The textured region comprises at least one (typically two or more) "ridge" that substantially surrounds the enclosure and that, after joining of the two bodies by compression bonding, provides a leakage barrier. Optional ridges between said two or more enclosure-surrounding ridges can further reduce the probability of leakage. The bodies exemplarily are Si bodies, with the enclosure serving to provide a controlled environment for a semiconductor laser. In another exemplary embodiment, the article is a flat panel field emission display.
