Patent ID: 6852616

Claim:
A method for producing a semiconductor device comprising: a first step of forming on a semiconductor substrate on which at least one semiconductor element is provided a first element electrode and a second element electrode electrically connected to the semiconductor element; a second step of forming an insulating film so as to cover the first element electrode and the second element electrode; a third step of forming a first opening for exposing at least one portion of the first element electrode and a second opening for exposing at least one portion of the second element electrode by selectively removing the insulating film; a fourth step of forming first substantially continuous, thin conductive film on the insulating film and within the first and second openings; a fifth step of forming a second, thick conductive film selectively on the first, thin conductive film so as to fill up the first opening and the second opening and extend over portions of the first, thin conductive film between the first and second openings; and a sixth step of patterning the first and second conductive films by removing only an upper portion of the selectively formed second, thick conductive film and portions of the first, thin conductive film uncovered by the second, thick conductive film, thereby forming a first external electrode connected to the first element electrode via the first opening immediately above the first element electrode, forming a second external electrode and forming a connecting wire having one end connected to the second element electrode via the second opening and the another end connected to the second external electrode on the insulating film.
