  • ISFETs fabrication method
    Patent number: 7067343
    Abstract: Methods for fabricating ion sensitive field effect transistors (ISFETs) with SnO2 extended gates. A SnO2 detection film is formed on a substrate by sol-gel technology to serve as an extended gate. The SnO2 detection film is electrically connected to a conductive wire, and an insulating layer is formed on the surface of the ISFET but part of the SnO2 detection film and the conductive wire are left exposed. The exposed conductive wire is electrically connected to a gate terminal of a MOS transistor.
