Abstract
An exemplary biosensor sensor for detecting the presence of a biological material includes an SOI substrate, a lateral BJT formed on at least a portion of the substrate, and a sensing structure formed on at least a portion of an upper surface of the BJT. The BJT includes an emitter region, a collector region and a base region, the base region being formed between the emitter and collector regions and laterally adjacent thereto. The sensing structure includes at least one dielectric layer contacting at least a portion of the base region. The dielectric layer forms a receptacle for confining a biological molecule being tested and is configured to respond to charges in biological molecules, the charges being converted to a sensing signal by the BJT.
