A method of making a plurality of sealed assemblies is provided which includes a) assembling a first element to a second element so that a bottom surface of the first element faces downwardly toward a front surface of the second element and a top surface of the first element faces upwardly away from the second element; and (b) forming ring seals surrounding regions of the front surface of the second element by introducing flowable material between the first element and the second element from the top surface of the first element through openings in the first element. A chip is provided which includes: (a) a body defining a front surface and one or more circuit elements on or within the body; (b) one or more bond pads exposed at the front surface in a bond pad region; and (c) a metallic ring exposed at the front surface, the ring substantially surrounding the bond pad region. Sealed chip assemblies are formed by sealing an array of the chips, e.g., in wafer form, to a cap element.

Capped chips and methods of forming a capped chip are provided in which electrical interconnects are made by conductive elements which extend from bond pads of a chip at least partially through a plurality of through holes of a cap. The electrical interconnects may be solid, so as to form seals extending across the through holes. In some cases, stud bumps extend from the bond pads, forming parts of the electrical interconnects. In some cases, a fusible conductive medium forms a part of the electrical interconnects.
