Abstract:
A method for manufacturing a semiconductor device in which a resistive element is provided on a semiconductor substrate, comprising the steps of:depositing a first conductor film on the semiconductor substrate intervened by an insulating member;depositing an insulating film on the first conductor film;patterning the insulating film to form an etching protection film;depositing a second conductor film on the etching protection film and the first conductor film; andforming a resistive film made of the first conductor film which is left over a region covered with either of the etching protection film and a resist film and forming a leading electrode of the resistive film made of the second conductor film which is left in a region covered with only the resist film by using, as etching masks, the etching protection film and the resist film having two regions, one of said two regions covers both ends of the etching protection film and the other region covers the second conductor film outside the etching protection film.
