A method for manufacturing a semiconductor device includes (a) providing a silicon carbide semiconductor substrate; and (b) forming an electrode structure on the silicon carbide semiconductor substrate by (i) forming a Schottky layer including a metal selected from the group consisting of titanium, tungsten, molybdenum, and chrome on a front surface of the silicon carbide semiconductor substrate; (ii) heating the Schottky layer to form a Schottky electrode which has a Schottky contact with the silicon carbide semiconductor substrate; and (iii) forming a surface electrode comprised of aluminum or aluminum including silicon on a surface of the Schottky electrode, while heating at a temperature range effective for the surface electrode to closely cover any uneven portion of the Schottky electrode and provide a surface electrode having a predetermined reflectance that is equal to or less than 80% so that an improved recognition rate by an automatic wire bonding apparatus is obtained.
