Abstract
PURPOSE:To eliminate contact resistance existing among many electrodes and a thermal-stress buffer sheet by a method wherein the many electrodes of a semiconductor substrate existing on an identical face of the semiconductor substrate is alloy-bonded to the comparatively thin thermal-stress buffer sheet whose coefficient of thermal expansion is nearly equal to that of the semiconductor substrate. CONSTITUTION:On an anode-side main face of a substrate 1 where a p-n junction has been formed on a silicon single-crystal sheet, an anode-side thermal- stress buffer sheet 7 composed of a metal whose coefficient of thermal expansion is nearly equal to that of silicon is alloy-bonded to a metal thin film 2 such as Al or the like. On a cathode-side main face of the substrate 1, an ohmic contact metal thin film used as strip-shaped cathode electrodes 3 and gate electrodes 4 is formed. A first cathode-side thermal-stress buffer sheet 5 which is composed of a material identical to that of the anode-side thermal-stress buffer sheet 7 and which is thinner than the sheet is alloy-bonded uniformly to the many cathode electrodes 3 which are arranged on the same face.
