Hybrid integrated circuit device and method for manufacturing same

A hybrid integrated circuit device comprising:

• an insulating substrate including an upper surface and a lower surface, the lower surface being formed with a plurality of wiring patterns for external connection, the plurality of wiring patterns including ends arranged along edges of the lower surface at a predetermined pitch;
• electronic components mounted on at least one of the upper surface and the lower surface of the insulating substrate, the electronic components being connected to the wiring patterns;
• a pair of insulating legs arranged at the edges of the lower surface of the insulating substrate, each of the insulating legs extending in parallel to the lower surface of the insulating substrate;
• and
• a plurality of terminal electrodes formed on each of the legs at the predetermined pitch to extend perpendicularly to the insulating substrate, the plurality of terminal electrodes being connected to corresponding ones of the wiring patterns formed on the lower surface of the insulating substrate;
• wherein each of the legs is bonded to the insulating substrate and formed with a plurality of electrode films connected to the terminal electrodes,
• wherein each of the legs is fixed to the insulating substrate by attaching the terminal electrodes to the corresponding ones of the wiring patterns on the lower surface of the insulating substrate by soldering or by adhesion of an electroconductive paste,
• wherein each of the legs includes an outer side surface formed with a plurality of outer side grooves arranged at a predetermined pitch, and an inner side surface formed with a plurality of inner side grooves arranged correspondingly to the outer side grooves, the terminal electrodes being provided in the inner side grooves and the outer side grooves, and
• wherein the electrode films connect the terminal electrodes in the outer side grooves to corresponding ones of the terminal electrodes in the inner side grooves.
