  • PREPARATION OF A PH SENSOR, THE PREPARED PH SENSOR, SYSTEM COMPRISING THE SAME AND MEASUREMENT USING THE SYSTEM
    Publication number: 20100140079
    Abstract: Preparation of a pH sensor, the prepared pH sensor, system comprising the same, and measurement using the system. The pH sensor is an extended gate field effect transistor (EGFET) structure. The preparation includes the steps of providing an extended gate ion sensitive field effect transistor comprising an extended gate region, forming a titanium nitride film on the extended gate region by RF sputtering deposition to obtain a pH sensor.
