    Abstract: A bio sensor is provided to reduce the production costs by using inexpensive bulk silicon substrate instead of expensive SOI(silicon on insulator) substrate, and improve sensing ability by electrically separating the substrate and sensing region through junction insulation. A bio sensor comprises: a first conduction type of semiconductor substrate(100) such as bulk silicon substrate; second conduction type of doped layers(110) formed on the semiconductor substrate; an electrode(120) formed in the upper parts of both ends of the doped layer; and probe molecules(130) immobilized to the doped layers, wherein the semiconductor substrate and doped layer are electronically separated through the junction insulation; and the doped layers have different immobilized probe molecules. A method for fabricating the bio sensor comprises the steps of: forming a second conduction type of doped layer on the first conduction type of semiconductor substrate; forming an electrode in the upper parts of both ends of the doped layer; and immobilizing the probe molecules to the doped layers. Further, the doped layers are epitaxial layers.
