Abstract:
1. A semiconductor device comprising: a first transistor including a first impurity region formed in the semiconductor substrate and a second impurity region formed in the semiconductor substrate; a second transistor including the first impurity region and a third impurity region formed in the semiconductor substrate; a first chalcogenide film formed over the first transistor and second transistor, the first chalcogenide film retaining data based on electric resistance; a first wiring formed over the first transistor and second transistor; and a second wiring formed over the first transistor and second transistor, wherein the first transistor and the second transistor share the first impurity region, wherein a bottom surface of the first chalcogenide film is electrically connected to the first impurity region, wherein a top surface of the first chalcogenide film is electrically connected to the first wiring, and wherein the second impurity region and the third impurity region are electrically connected to the second wiring.
