Abstract

A hybrid integrated circuit device is provided with: a microcomputer, a plurality of peripheral circuit elements, and a non-volatile memory which is positioned adjacent to the microcomputer, all of which are interconnected by a plurality of specified conductive paths; pair of integrated circuit substrates on which is formed the conductive paths and a casing provided with the pair of integrated circuit substrates secured to the upper and lower surfaces of the casing, forming a sealed space between these surfaces. The microcomputer and the peripheral circuit elements are positioned in the sealed space and only the non-volatile memory is positioned in an exposed space. The hybrid integrated circuit device of the present invention has a compact and simple form with a high degree of mounting density as well as superior handling capabilities and reliability.
