Abstract
Abstract An integrated circuit device has a frame of semiconductor material and blocks of the same semiconductor material situated in a space or spaces substantially enclosed by the frame, with the blocks being spaced from the frame and having circuit elements therein which are interconnected by beam leads also functioning as the sole means mechanically coupling or locating the blocks relative to the frame. Certain of the beam leads project beyond the periphery of the frame and all of the beam leads are substantially coplanar and constitute the highest elevations on the circuit device so that the projecting beam leads can be conveniently bonded to conductive areas on a substrate, such as a circuit board, defining external circuits.
