Abstract
A method of making nano-scaled channel, the method including: locating a first photoresist layer, a nanowire structure, and a second photoresist layer on a surface of a substrate, and the nanowire structure being sandwiched between the first photoresist layer and the second photoresist layer, wherein the nanowire structure comprises an nanowire; forming an opening in the first photoresist layer and the second photoresist layer to expose a portion of the surface of the substrate to form an exposed surface, wherein a part of the nanowire is exposed and suspended in the opening, and both ends of the nanowire are sandwiched between the first photoresist layer and the second photoresist layer; and depositing a thin film layer on the exposed surface of the substrate using the a nanowire as a mask, wherein the thin film layer defines a nano-scaled channel corresponding to the at least one nanowire.
