Patent ID: 7541227

Claim:
A method for forming a thin film device, comprising: forming a first at least semi-conductive strip located at a first height relative to a surface of a substrate; forming a second at least semi-conductive strip adjacent to the first at least semi-conductive strip, the second strip located at a second height relative to the substrate surface, the second height being different than the first height; and forming a nano-gap between the first and second at least semi-conductive strips; wherein forming the first strip, the second strip, and the nano-gap is accomplished by: establishing an insulating layer on the substrate; establishing a mask layer on the insulating layer; removing at least a portion of the mask layer to form at least one trench; removing a portion of the insulating layer adjacent the at least one trench, thereby exposing a portion of the substrate; and establishing an at least semi-conductive material on the remaining mask layer to form the first strip, and on at least a portion of the exposed substrate to form the second strip.
