제목 | Characteristics of Non-IGZO-Based Oxide TFTs Fabricated under Various Film Deposition Conditions |
초록 | Indium-Gallium-Zinc-Oxide (IGZO)-based materials have been widely used in fabricating oxide thin-film transistors (TFTs) due to their beneficial properties such as high mobility and availability of low temperature process. However, as IGZO patents are owned by Japan and the prices of indium and gallium are expensive, a need for discovering non-IGZO-based materials emerged, which can reduce dependency on indigenous patents and lower the price of materials. As a method of fabricating oxide TFTs, vacuum processes such as sputter and atomic layer deposition (ALD) are mainly used, and low-cost solution processes are also used. In this study, we fabricated non-IGZO-based oxide TFTs under various film deposition conditions and evaluated its characteristics.The fabricated TFTs exhibited n-type characteristics with a field-effect mobility of 2.94cm2/Vs, subthreshold swing (SS) of 0.653V/decade, and an on/off ratio of 2.7 x 105. |
