Claim:
1. A method of manufacturing a nano gap sensor, the method comprising: (a) forming one or more concave portions having notch shapes at an edge of a surface of a substrate; (b) forming an insulating layer on the surface of the substrate on which the one or more concave portions are formed so that a crack, which occurs when a residual stress generated between the substrate and the insulating layer concentrates at a sharp end of the one or more concave portions, propagates and forms a nano gap crossing over the surface of the substrate and having a depth corresponding to an entire thickness of the one or more concave portions and the insulating layer; (c) forming one or more sensing patterns on the insulating layer, wherein the one or more sensing patterns cross over the nano gap; and (d) forming electrodes at opposite ends of the one or more sensing patterns.
