Abstract

Carbon nitride films were deposited on various substrates for humidity sensors with meshed electrode by reactive RF magnetron sputtering system. As the ratio of injected nitrogen was decreased, the sensitivity of sensor was increased. When the ratio of injected nitrogen was 50~70%, the sample showed the best linearity. The sensor impedance changed from 95.4k to 2.1k in a relative humidity range of 5% to 95%. The humidity sensors based on silicon wafer revealed higher lineality and faster response than those of alumina or quartz substrates. The adsorption saturation time of the sample was about 80sec, and its desorption time was about 90sec.
