- 요약The 21st century's data-intensive applications demand advanced solutions in electronics, with three-dimensional (3D) integration of diverse devices and integrated circuits standing at the forefront. To meet these requirements, sequential fabrication of multiple device layers on rigid substrates like silicon presents a promising avenue, enabling enhanced scaling, computational capacity, and speed. Crucially, this approach requires sufficiently low-temperature (sub-500 ℃) integration to maintain the performance of underlying devices. In effect, low-temperature fabrication of electronics can enable both sequential 3D integration, and other applications like flexible electronic devices.In this thesis, I first examine the potential of n-type semiconductor oxides for transistors fabricated at temperatures below 300 ℃. The focus is on utilizing ~4 nm thin sputtered indium tin oxide (ITO) as the channel material in various transistor configurations. By investigating the critical process parameters that influence the threshold voltage of ITO transistors, I discuss the fabrication of high-performance dual-gated ITO transistors with channel lengths down to ~60 nm. Additionally, I assess the stability of the threshold voltage in ITO transistors under gate bias and temperature stress, to evaluate their reliability for practical applications.Next, I explore the low-temperature (sub-200 ℃) fabrication of p-type chalcogenide transistors, showcasing a broader spectrum of materials suitable for back-end-of-line applications. Finally, I introduce a novel transfer method for achieving well-aligned nanoscale transistors and other devices usually built at higher temperatures, on thermally limiting flexible substrates.In summary, the presented studies demonstrate multiple pathways for the lowtemperature integration of multifunctional electronics, with n-type oxide transistors, particularly those utilizing ITO, at the center of this advancement. These findings not only enhance the understanding of oxide transistor functionality and reliability but also pave the way for innovative applications in both rigid and flexible electronic devices, underscoring the pivotal role of low-temperature processes in future electronic integration.
