Abstract: PURPOSE: To obtain a transistor the hFE of which is different from each other in the same area by changing the thickness of Pt-Al alloy and by forming Schottky diodes, the forward characteristics of which are different from each other in the same area, in the same chip.  
     CONSTITUTION: The embedded layer 1 and epitaxial layer 3 are formed on the Si substrate 2, the insulating isolation layer 4, base layer 5 and guard ring 5a are provided. After the element is selectively coated with Pt11, Pt is spattered over the entire surface and sintered under a proper condition. After this, when the Pt is removed from the surface, only platinum silicide is remained. By this, the thick platinum silicide 11a and thin one 11b are formed. Next when Al is evaporated onto the silicide to alloy them, they are altered to aluminum silicide 12a, 12b and when the Pt-Al layer is made thick, a drop of forward voltage of the Schottky diode is made remarkable. In this way, the hFE of transistor of the same area in the same chip is controlled by changing the thickness of Pt-Al alloy on the emitter, the characteristics of IC in which Schottky diodes are used can be improved.
