A study was conducted to demonstrate the fabrication of high-performance zinc oxide (ZnO) transistors and circuits using spray pyrolysis (SP) deposition technique in ambient atmosphere. The method was found to be compatible with large-area deposition and potentially addressed the issues of manufacturing cost and high operating voltages. High mobility n-channel thin-film transistors (TFTs) based on ZnO deposited at substrate temperatures in the range of 200-500 °C were realized to demonstrate the method. Semiconductor deposition was performed entirely in ambient atmosphere without the need for special precautions. It was demonstrated that the as-deposited ZnO films were of high quality and uniformity, while the SP was compatible with a number of solution-processible self-assembled monolayer (SAM) dielectrics. ZnO transistors operating at significantly low voltages were demonstrated by combining SP with soluble SAM dielectrics.
