Thin Film Transistor fabricated with CIS semiconductor nanoparticle

Thin Film Transistor(TFT) having CIS (CuInSe) semiconductor layer was fabricated and characterized. Heavily doped Si was used as a common gate electrode and PECVD Silicon nitride ($SiN_x$) was used as a gate dielectric material for the TFT. Source and drain electrodes were deposited on the $SiN_x$ layer and CIS layer was formed by a direct patterning method between source and drain electrodes. Nanoparticle of CIS material was used as the ink of the direct patterning method.
