Abstract
PURPOSE:To cut down the manufacturing processes by alloying an impurity material arranged between an anode region and a metallic sheet. CONSTITUTION:An impurity diffusing process and an alloying process are simul taneously performed by alloying a material 21 comprising an impurity to be a life time killer arranged between an anode region 4 and a metallic sheet 4. In other words, the temperature for diffusing the life time killer such as gold, platinum etc., is almost similar to that for junctioning the metallic sheet 9 such as molybdenum, tungsten etc., by alloying process. Consequently, when said material 21 arranged between the anode region 4 and the metallic sheet 9 is alloyed, the life time killer is diffused in the semiconductor layer through the intermediary of the anode region 4 simultaneously the metallic sheet 9 is junctioned with the surface of the anode region 4. Through these procedures, the manufacturing process can be cut down while eliminating the installation of new diffusion furnace.
