A metal-insulator-gap-insulator-semiconductor sensing device has been characterized in different pH solutions and with different single strand DNA solutions by capacitance-voltage measurements. The capacitance-voltage curves show the difference from pH and the difference from DNA base by hysteresis and flat band voltage shift due to mobile ionic charge in the solution. As the pH decreases, the flat band voltage shift increases in the pH range of 2.7 to 7.0. The hysteresis in the capacitance-voltage curves shows the influence of ionic charge in the solutions and the change of the sensing surface condition. The difference of the flat band voltage shift in the capacitance-voltage curves is related to the mobile ionic charge in the solutions due to pH or DNA molecules.

The integration of optics on a silicon (Si) substrate through metal-oxide-semiconductor (MOS) compatible processes is becoming important for optical interconnects, image sensors or monolithic optical biosensors [1]. The MOS tunneling structure has used as a photodetector [2]. However, the indium tin oxide sputtering process has been reported to degrade photodetector performance. In this study, we have examined the photodetector characteristics of MOS diodes with tin oxide (SnO2)/ultrathin silicon dioxide (SiO2)/n-Si structures.
