- Provided are a biosensor with a silicon nanowire and a method of manufacturing the same, and more particularly, a biosensor with a silicon nanowire including a defect region formed by irradiation of an electron beam, and a method of manufacturing the same. The biosensor includes: a silicon substrate; a source region disposed on the silicon substrate; a drain region disposed on the silicon substrate; and a silicon nanowire disposed on the source region and the drain region, and having a defect region formed by irradiation of an electron beam. Therefore, by irradiating a certain region of a high-concentration doped silicon nanowire with an electron beam to lower electron mobility in the certain region, it is possible to maintain a low contact resistance between the silicon nanowire and a metal electrode and to lower operation current of a biomaterial detection part, thereby improving sensitivity of the biosensor.
