Abstract:
Ion sensor based on differential measurement comprising an ISFTET-REFET pair wherein the REFET is defined by a structure composed of an ISFET covered by a microreservoir where an internal reference solution is contained. The sensor comprises a first and a second ion-selective field effect transistor, an electrode, a substrate on the surface whereof are integrated the two transistors, connection tracks and the electrode and a structure adhered on the first ion-selective field effect transistor which creates a microreservoir on the gate of said first transistor, with the microreservoir having a microchannel which connects the microreservoir with the exterior and the microreservoir being filled with the reference solution.

Claim (Index 29):
A method of manufacturing an ion sensor based on differential measurement, the method comprising the following phases:\n integrating a plurality of ion-selective field effect transistors spaced on a first wafer, wherein each of the plurality of ion-selective field effect transistors includes a gate; coupling a second wafer of bondable material on the first wafer, creating a plurality of spaced microreservoirs and microchannels in correspondence with the plurality of ion-selective field effect transistors, so that each microreservoir and at least one microchannel of the plurality of spaced microreservoirs and microchannels are situated in correspondence and aligned with each ion-selective field effect transistor of the plurality of ion-selective field effect transistors; cutting the first wafer transversally to create a plurality of first ion-selective field effect transistors wherein each of the first ion-selective field effect transistors comprises a microreservoir and at least one microchannel from the plurality of spaced microreservoirs and microchannels; and for each of the first ion-selective field effect transistors comprising a microreservoir and at least one microchannel:\n fixing at least one second ion-selective field effect transistor, an electrode and one or more connection tracks, wherein the at least one second ion-selective field effect transistor includes a gate; \n connecting the one or more connection tracks to the first ion-selective field effect transistor comprising a microreservoir and at least one microchannel, and to the at least one second ion-selective field effect transistor.
