Abstract

A microjoint interconnect structure comprising a dense array of metallic studs of precisely controllable height tipped with a joining metallurgy. The array is produced on a device chip that is to be attached to a carrier, or to a carrier along with other devices, some of which may be selected to have similar interconnect structures so as to form all together an assembled carrier that functions as a complete computing, communications or networking system.
