ISFET MOSFET MIM capacitor Reference electrode pH detection Chemical sensor CMOS processing. | |
In this work, we show that by using Metal-Insulator-Metal (MIM) structures integrated in series to the gateof submicron Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) devices, highly-sensitive and ultra-lowpower consumption pH sensors can be obtained. One MIM capacitor enables external polarization of the MOSFETdevice while a second MIM capacitor is connected to a sensing plate whose surface is whether a thick polyimidelayer or the last metallization level. The electrochemical response of these surfaces to pH buffer solutions resemblesthat of Ion-Sensitive Field-Effect Transistor (ISFET) devices whose pH sensitivity is dependent on the type of surfacematerial being exposed. | |
