Abstract

PURPOSE: To avoid the deterioration of the characteristics of transistor and Schottky barrier diode by employing titanium (Ti) controlled in its thickness as the lower layer of an electrode and aluminum controlled in its content as the lower layer thereof when forming the transistor and the Schottky barrier diode on the same semiconductor substrate.
CONSTITUTION: A p-type base region 5 is formed for a transistor in an n-type silicon substrate 1 becoming a collector, and an n-type emitter region 6 is similarly formed for the transistor therein, and an insulating film 2 is coated on the entire surface thereof. Then, a predetermined opening is perforated in the film 2, and polycrystalline silicon conductive layer 7 making contact with the regions 5 and 6 is formed while extending it on the film 2 in such a manner that the region I making contact with the region 5 is employed as a Schottky barrier diode and the region II making contact with the region 6 as a transistor. Then an aluminum layer 8 containing silicon is coated through the Ti layer 3 having approx. 100Å thick on the layer 7 as a electrode. At this time the layer 3 is selected not only from Ti but Hf, Cr, etc., and the silicon amount contained in the layer 8 is controlled by weight to higher than 0.6%.
