SBIR Phase I: Aqueous Inks for High Performance Oxide Electronics

这项小企业创新研究（SBIR）第一阶段项目旨在开发用于驱动有源矩阵有机发光二极管（AMOLED）显示器的薄膜晶体管器件的半导体和介电油墨。该方法是采用具有低凝结能垒的新型水基无机前驱体，这将使高质量电子薄膜的溶液沉积能够经济有效地缩放到均匀的大型衬底上。该项目将无机油墨设计与印刷电子产品的闪光灯工艺相结合，以制造晶体管。它有望满足玻璃上AMOLED显示器具有挑战性的性能要求，并直接通向低温柔性基板。通过调整前驱体配方以获得最佳吸光度和调整闪光灯脉冲条件，完成脱水所需的能量将精确地沉积在薄膜中，对衬底的热影响最小。该项目的更广泛/商业影响将是提供半导体和介电油墨的潜力，以实现更节能的AMOLED显示器。AMOLED是显示行业中增长最快的细分市场。相关先进晶体管材料的潜在服务市场规模约为1亿美元。该项目开发的材料和低温工艺也将为无机印刷电子和大面积介电/光学涂层的更广泛应用奠定基础。

This Small Business Innovation Research (SBIR) Phase I project aims to develop semiconductor and dielectric inks for thin-film transistor devices to drive Active Matrix organic light-emitting diode (AMOLED) displays. The approach is to employ novel aqueous-based inorganic precursors with low energy barriers to condensation, which will enable the solution deposition of high-quality electronic films that can be cost-effectively scaled to large substrates with uniformity. This project will combine inorganic ink design with flashlamp process for printed electronics to fabricate transistors. It is expected to meet the challenging performance requirements for AMOLED displays on glass with a direct path to low temperature flexible substrates. By tuning the precursor formulation for optimum absorbance and adjusting the flashlamp pulse conditions, the energy required to complete dehydration will be deposited precisely in the film with minimal thermal impact on the substrate. The broader/commercial impact of this project will be the potential to provide semiconductor and dielectric inks to enable more energy efficient AMOLED displays. AMOLED is the fastest growing segment in display industry. The potential served market for related advanced transistor materials will be about $100 million. The materials and low temperature processes developed in this project will also lay the foundation for much broader applications in inorganic printed electronics and large-area dielectric/optical coatings.
