Patent ID: 8546783

Claim:
A semiconductor device comprising: a first transistor, a second transistor, and a memory cell; a semiconductor substrate; a first ion implanted region formed in the semiconductor substrate, and which is a part of the first transistor; a second ion implanted region formed in the semiconductor substrate, and which is a part of the first transistor; a third ion implanted region formed in the semiconductor substrate, and which is a part of the second transistor; a fourth ion implanted region formed in the semiconductor substrate, and which is a part of the second transistor; a phase change film formed over the semiconductor substrate and extended in a first direction, and which is a part of the memory cell; an electric conduction film formed on the phase change film and extended in the first direction; a first metallic film formed over the electric conduction film and extended in a second direction which is perpendicular to the first direction; a second metallic film formed over the electric conduction film and extended in the second direction; a first plug electrically connected to the first metallic film and the first ion implanted region; a second plug electrically connected to the phase change film and the second ion implanted region; a third plug electrically connected to the second metallic film and the third ion implanted region; and a fourth plug electrically connected to the phase change film and the fourth ion implanted region.
