Patent ID: 8241939

Claim:
A method of manufacturing a semiconductor nanowire sensor device, comprising: etching a first conductivity-type single crystalline silicon layer which is a top layer of a Silicon-On-Insulator (SOI) substrate to form a first conductivity-type single crystalline silicon line pattern; doping both sidewalls of the first conductivity-type single crystalline silicon line pattern with impurities of a second conductivity-type opposite to the first conductivity-type to form a second conductivity-type channel; forming second conductivity-type pads for forming electrodes at both ends of the first conductivity-type single crystalline silicon line pattern; forming, in an undoped region of the first conductivity-type single crystalline silicon line pattern, a first electrode for applying a reverse-bias voltage to insulate the first conductivity-type single crystalline silicon line pattern and the second conductivity-type channel from each other; and forming a second electrode for applying a bias voltage across the second conductivity-type channel on the second conductivity-type pad.
