- the present invention relates to a semiconductor sensor chip and a semiconductor sensing device that are highly practical and liquid-proof.
- Ion sensing systems and biosensing systems are applied to a wide range of fields such as food production management and environmental measurement.
- Ion's biosensing there is an increasing demand for sensing at the ion and molecular level, such as single molecule recognition and single base recognition, and systems and devices that can sense it are needed.
- system and device fine integration and on-chip integration are required.
- a typical example of an ion sensing device is an ion sensitive field effect transistor (ISFET) having a silicon nitride film Z silicon oxide film Z silicon structure.

- the reference electrode a separate glass electrode is used, and on-chip and miniaturization are not attempted.
- the silicon nitride film which is an ion-sensitive film, has a thickness of 100-200 nm (nanometers) and is used.
- the conventional technology has a difficulty in satisfying the demands of on-chip, miniaturization, and integration! It is essential to extract the maximum effect in detection of single molecule ions. It is thought that a fundamental improvement will be necessary. Furthermore, in ion sensing systems and biosensing systems, for example, a semiconductor device that assumes measurement in a solution that can be measured by immersing the sensor in the solution and maintaining the detection unit in contact with the solution for a long time. Is particularly necessary.
