Abstract

A semiconductor device comprises a semiconductor substrate, an interlayer insulating film formed on the semiconductor substrate, a first pad, a second pad and a conductor. The first pad is formed on the interlayer insulating film and its circumferential edges are covered with a first surface-protecting film. The second pad formed on the interlayer insulating film facing the first pad across a second surface-protecting film, and its circumferential edges are covered with a third surface-protecting film. The conductor is provided continuously on the first pad, the first to third surface-protecting films, and the second pad.

Claims (37)

1. A semiconductor device comprising:

a semiconductor substrate;

an interlayer insulating film formed on the semiconductor substrate;

a first pad formed on the interlayer insulating film and whose circumferential edges are covered with a first surface-protecting film;

a second pad formed on the interlayer insulating film facing the first pad across a second surface-protecting film, and whose circumferential edges are covered with a third surface-protecting film; and

a conductor provided continuously on the first pad, the first to third surface-protecting films, and the second pad,

wherein the first pad is a fixed-potential pad, and the second pad is an option-setting pad and is electrically connected to an internal circuit by an internal wiring.

2. The semiconductor device according to claim 1 , further comprising:

an internal wiring formed between the semiconductor substrate and the interlayer insulating film; and

a third pad formed on the interlayer insulating film whereto a thin metal wire is connected,

wherein the first pad is connected to the internal wiring, and has an area smaller than the area of the third pad.

3. The semiconductor device according to claim 1 , wherein the first to third surface-protecting films are separated into the portions in contact with the conductor and other portions.

4. The semiconductor device according to claim 1 , further comprising one or more option-setting pads on which the conductor is further continuously provided.

5. The semiconductor device according to claim 1 , wherein the first pad and the second pad face each other at two or more sides.

6. The semiconductor device according to claim 1 , wherein the contact area of the conductor and the first pad differs from the contact area of the conductor and the second pad.

7. The semiconductor device according to claim 1 , wherein the conductor comprises:

a first conductor provided on the first pad and the first and the second surface-protecting films; and

a second conductor provided on the first conductor, the second pad, and the third surface-protecting film.

8. The semiconductor device according to claim 1 , wherein the conductor comprises:

a first conductor element provided on the first pad;

a second conductor element provided on the second pad; and

a third conductor element provided on the first and second conductor elements.

9. A semiconductor device comprising:

a semiconductor substrate;

an interlayer insulating film formed on the semiconductor substrate;

a first pad formed on the interlayer insulating film and whose circumferential edges are covered with a first surface-protecting film;

a second pad formed on the interlayer insulating film facing the first pad across a second surface-protecting film, and whose circumferential edges are covered with a third surface-protecting film; and

a conductor provided continuously on the first pad, the first to third surface-protecting films, and the second pad; and

a dummy pad formed between the first pad and the second pad, and whose circumferential edges are covered with a fourth surface-protecting film;

wherein the conductor is continuously provided also on the dummy pad and the fourth surface-protecting film.

10. A semiconductor device comprising:

a semiconductor substrate;

an interlayer insulating film formed on the semiconductor substrate;

a first pad formed on the interlayer insulating film and whose circumferential edges are covered with a first surface-protecting film;

a second pad provided inside the second pad across a second surface-protecting film; and

a conductor continuously provided on the first pad, the second surface protecting film, and the second pad,

wherein one of the first pad and the second pad is a fixed-potential pad, and another of the first pad and the second pad is an option-setting pad and is electrically connected to an internal circuit by an internal wiring.
