Abstract
The invention discloses a sensitive field effect transistor apparatus, which uses an inorganic membrane to sense hydrogen ions. The invention adopts the membrane with high deformation stress. The sensitivity of the sensitive membrane to hydrogen ions is adjusted through altering the membrane thickness and changing the substrate type and doped concentration. A differential amplifier is used to read a signal to form the inorganic Ion Sensitive Field Effect Transistor/Reference Field Effect Transistor apparatus.
