제목 Solution-Processed Oxide Dielectrics via Large-Area Printing Method for Metal-Oxide Transistor Arrays with Direct Patterning
초록 In this work, we demonstrate the fabrication of thin and densified sol–gel metal oxide films for high performance gate dielectric layers by a simple bar-printing method in large-area scale for thin-film transistor arrays. The control range of thin film thickness of single-coated aluminum and hafnium oxide dielectric films can be achieved with a nano-scale resolution (>40 nm) by adjustable solution rheological factors (e.g. shearing speeds and solution concentrations). The fabricated high-quality oxide dielectric layers exhibited remarkable electrical performances such as very low leakage current density and very high areal capacitance with excellent smooth surface properties with very uniform large-area coverage up to 4-inch silicon wafer. Lastly, in accompany with direct-solution patterning process, solution-bar-coated metal oxide transistor arrays were performed with sufficient transistor performance under very low operation voltage below 2V with a sol-gel semi-conducting material.
