Patent ID: 8652337

Claim:
A method for fabricating nanochannels for a nanodevice, the method comprising: depositing an electrically insulating film on a substrate; patterning a nanowire on the electrically insulating film; depositing an electrically insulating material on both the nanowire and the electrically insulating film; forming a first circular hole in the electrically insulating material as an inlet, the first circular hole formed over a first tip of the nanowire, the first circular hole exposing the first tip; forming a second circular hole as an outlet, the second circular hole formed over a second tip of the nanowire opposite the first tip, the second circular hole exposing the second tip; forming a nanochannel connecting the first circular hole to the second circular hole by etching away the nanowire via flowing an etchant in the first circular hole and out the second circular hole; attaching a first reservoir over the first circular hole to be in connection with the nanochannel at a previous location of the first tip; and attaching a second reservoir over the second circular hole to be in connection with the nanochannel at a previous location of the second tip.
