Claims20
A semiconductor device comprising:
- a first electrode;
- a second electrode disposed adjacent to and in electrical contact with the first electrode;
- and
- a barrier element disposed between the first electrode and the second electrode;
- wherein the barrier element comprises randomly nucleated regions.
A semiconductor device comprising a first electrode, randomly nucleated material regions disposed upon the first electrode, and a second electrode disposed in a pattern in electrical communication with the first electrode and the randomly nucleated material regions.
A method of fabricating a semiconductor device, the method comprising:
- fabricating a first electrode of the semiconductor device;
- randomly nucleating material regions upon a surface of the first electrode;
- and
- forming a second electrode upon the first electrode and at least a portion of the randomly nucleated material regions.
