Abstract:
1. A nano semiconductor switch device comprising: a semiconductor substrate; a first conductive layer on the semiconductor substrate; a second conductive layer on the first conductive layer; a first insulating layer on the second conductive layer and the semiconductor substrate, the first insulating layer defining a contact hole that exposes at least a portion of the second conductive layer; a third conductive layer on the first insulating layer, the third conductive layer having an air gap configured such that a side of the third conductive layer is outwardly spaced apart from the contact hole; and carbon nano tubes on the exposed portion of the second conductive layer in the contact hole, the carbon nano tubes being substantially extended from an upper surface of the third conductive layer in a vertical direction with respect to the semiconductor substrate, wherein the air gap electrically separates the carbon nano tubes from the side of the third conductive layer.
