A semiconductor integrated circuit includes a thermal resistor which is made of a tungsten silicon nitride containing at least about 5% by weight of silicon and formed on a semiconductor substrate directly or via an insulating film. The semiconductor integrated circuit is produced by a method including the steps of: forming a tungsten silicide nitride film on a semiconductor substrate; patterning the tungsten silicide nitride film in a predetermined pattern to form a thermal resistor; and forming a pair of electrodes to be connected to the thermal resistor. The semiconductor integrated circuit is provided so as to have a predetermined resistance by measuring electric characteristics of the semiconductor integrated circuit; obtaining a difference between the measured electric characteristics and desired electric characteristics to calculate a required adjusting amount of a resistance of the thermal resistor; and adjusting the resistance of the thermal resistor by the adjusting amount through heating of the thermal resistor with electric power.
