  • Patent number: 10330637
    Abstract: A system and method for chemical sensing of multiple gases or vapors with an array of chemical sensitive field effect transistor (CS-FET) devices that are highly sensitive, small in size and have low energy consumption. The sensor layer is an ultrathin film of transition metal oxide, rare earth metal oxide or metal nanoparticles that is formed between the source and drain electrodes on a silicon substrate. The work functions of the sensor layer can be manipulated by the adsorption of chemicals onto their surfaces. These changes cause a change in the surface potential of the underlying Si channel, leading to the current modulation of the devices. By selecting appropriate sensor layers, different chemicals will produce different output signals. External signal processing of these signals enables and sensor and array profile matching permits multi-gas detection.
