Method of shaping inter-substrate plug and receptacles interconnects

A method electrically and mechanically interconnects two surfaces of high density first and second semiconductor devices. The first semiconductor device (10) is formed with plug members (22) connected to nodes (18) of its circuit elements (14) and protruding from the first semiconductor device. The second semiconductor device (24) is formed having receptacle members (36) connected to nodes (32) of its circuit elements (28) and protruding from the second semiconductor device. The plug members are inserted into the receptacle member to interconnect the first and second semiconductor devices. The plug members may be removed from the receptacle member to disconnect the first and second semiconductor devices.
