  • SELF-ALIGNED WELL STRUCTURES FOR LOW-NOISE CHEMICAL SENSORS
    Publication number: 20150168345
    Abstract: In one implementation, a chemical detection device is described. The device includes a chemically-sensitive field effect transistor including a floating gate conductor coupled to a gate dielectric and having an upper surface, and a sensing material on the upper surface. The device also includes a fill material defining a reaction region extending above the sensing material, the reaction region overlying and substantially aligned with the floating gate conductor.
    Type: Application
