Abstract

Thin film transistors (TFTs) with nitrogen incorporated indium zinc tin oxide (IZTO:N) channel layer were fabricated and characterized. For the IZTO:N channel, TFTs was fabricated on heavily doped Si as a common gate electrode and silicon nitride (SiNx) was used as a gate dielectric layer. The IZTO:N layer was formed by spin-coating as precursor type solution and annealed at 600°C The precursors for indium, zinc, and tin were indium chloride, zinc chloride, and tin chloride. The incorporation of nitrogen was accomplished by addition of NH4OH solution. The IZTO:N TFT prepared with the precursor solution having 0.7% NH4OH has show the performance in mobility 1.2cm2/Vs, Ion/off of 106 and threshold voltage of 8.5 V.
