Filed: 1985-08-20
Abstract: PURPOSE:To decrease electric and thermal contact resistance between an electrode body and an electrode to a large extent when the connecting electrode body is compressed and contacted to the electrode on the protruded surface of a curved semiconductor substrate, by filling the recess part of the main surface of the semiconductor substrate, in which the recess part and the protruded part are formed, with an insulating body, and depositing a common electrode layer on the protruded surface and the surface of an insulating body. CONSTITUTION:The recess part of the main surface of a semiconductor substrate 1 is filled with an insulating body 5 of, e.g., polyimide resin and insulating polycrystalline silicon. Thus, the main surface is flattened. The insulating body 5 is filled on a gate electrode 3. The central part of the gate electrode 3 is exposed for connection to the outside. The upper surface of the insulating body 5 is continued to the upper surface of a protruded part 11. A metal layer 2 is deposited on the resultant continuous surface, and a cathode electrode is obtained. A cathode connecting electrode body 4 is contacted with the surface of the common cathode electrode 2. Therefore the compressed contact area is increased even if there is a slight curve in the substrate 1 or the electrode body 4. Dispersion in current density due to the difference in contact pressure is not yielded without the total area contact.
