Abstract:
1. A structure of a nano device transistor for a biosensor, comprising: a silicon substrate having SiO a bottom gate positioned on the silicon substrate having SiO a gate dielectric layer positioned on the bottom gate being an interface layer for insulating the bottom gate; a nano channel layer positioned on the gate dielectric layer; a drain positioned extending over a first portion of a top surface of the nano channel layer and a first portion of a top surface of the gate dielectric layer; a source positioned extending over a second portion of the top surface of the nano channel layer and a second portion of the top surface of the gate dielectric layer; a ceiling gate dielectric layer comprising a first ceiling gate dielectric layer portion and a second ceiling gate dielectric layer portion positioned on the drain and the source, respectively; a ceiling gate positioned on the ceiling gate dielectric layer; a first protection layer positioned on the first ceiling gate dielectric layer portion; and a second protection layer positioned on the second ceiling gate dielectric layer portion.
