This research aims at exploring an entirely new electronic device Fin-IGBA for detection of ions or charged molecules with ultimate sensitivity at the single-charge level. It is expected to generate new knowledge in electronic sensing and to impact areas of Life Sciences and Life Science Technologies. It is of specific importance in application areas such as early detection of diseases, environmental and bioprocess analysis, food quality and security monitoring. Technologically, a Fin-IGBA integrates nanowire-based sensing channels with an internal bipolar signal amplifier. It will result in a compact, highly sensitive biochip system with fast response and excellent noise immunity. In detail, we will establish a stable baseline for production of nanowires and nanowire arrays with desired dimensions and of spectacular surfaces; establish and incorporate a physics-based device model for Fin-IGBA to serve the purpose of guiding our device design; develop process modules for the Fin-IGBA device integration; fabricate and characterize Fin-IGBA of an optimized layout geometry of the FET for high charge sensitivity, an optimum internal current amplification of the BJT and an effective suppression of the latch-up risk; make proof-of-concept demonstration of the proposed idea by detecting ions with an instantaneous response. Through this research, we aim at establishing world-leading competence in exploitation of standard Si technology for health applications at Uppsala University.
