项目摘要

Organic semiconductors will enable technologies like displays, detectors, and biomedical sensors that are light weight, flexible, and low-cost. Manufacturing electronic devices requires the ability to pattern different materials in separate layers to define the design space for a device. A significant obstacle for the development of organic electronic devices is the lack of a patterning technology with the disruptive power that photolithography exerted in traditional microelectronics. There is therefore a critical need to develop scalable and rapid photopatterning methods capable of producing organic semiconductor structures with sub-micrometer resolution. Just as the three-dimensional 3D printer is an enabling tool for low cost part fabrication, this Scalable NanoManufacturing (SNM) award will enable development of solution processing steps for the fabrication of nanoscale multi-layer organic electronic devices. This research involves collaboration between science, engineering, and industry partners in chemistry, materials, optical processing, and chemical process development. The fundamental knowledge needed for nanomanufacturing will be integrated into university curricula and transferred to undergraduate students through research internships. Graduate students will experience hands-on industry partnerships through collaboration with Palo Alto Research Center (PARC). The next generation of researchers, particularly minorities, will be engaged through involvement in 4-H projects in electronics.Resolution on solution-printed organic electronics has been limited to 10's of µm due to the inherent limitations of solution printing or evaporation through a shadow mask. Photolithography has also been limited due to mutual solubility and miscibility of organic materials and material damage associated with photomask removal. In this research program we develop a new approach in which the solubility of the organic semiconductor itself is controlled by photo-reversible charge-transfer chemistry, enabling diffraction-limited patterning of organic electronic materials. This technical breakthrough enables the patterning of either the organic semiconductor or the doping level within the semiconductor using light exposure. The research team will explore chemical synthesis of new charge transfer dopants to enable the application of this technology to a broader array of semiconductors, optical processing to reduce write times and feature size, and chemical processing to make each sequential step consistent with high-throughput roll-to-roll processing, the ultimate focus of which is the development of all-organic transistor arrays with doped organic electrodes, patterned gates, and high switching speeds. The nanomanufacturing process will be scaled-up to large areas using student internships and equipment at PARC.

有机半导体将使显示器、探测器和生物医学传感器等重量轻、柔性和低成本的技术成为可能。制造电子设备需要能够在不同的层中对不同的材料进行图案化，以定义设备的设计空间。有机电子器件发展的一个难题是缺乏具有光刻在传统微电子学中所发挥的颠覆性能力的图案化技术，因此迫切需要开发能够生产亚微米分辨率有机半导体结构的可扩展且快速的光图案化方法。只是由于三维 3D 打印机是低成本零件制造的有利工具，因此可扩展纳米制造 (SNM) 奖项将有助于开发用于制造纳米级多层有机电子器件的解决方案处理步骤。这项研究涉及科学、技术和技术之间的合作。化学、材料、光学加工和化学工艺开发方面的工程和行业合作伙伴将把纳米制造所需的基础知识纳入大学课程，并通过研究实习将其传授给本科生，研究生将体验实践行业合作伙伴关系。通过与帕洛阿尔托研究中心 (PARC) 的合作，下一代研究人员，特别是少数族裔，将通过参与电子学领域的 4-H 项目来参与。由于溶液印刷有机电子学的分辨率仅限于 10 微米。由于有机材料的互溶性和混溶性以及与光掩模去除相关的材料损坏，通过光掩模进行溶液印刷或蒸发的固有局限性也受到限制。其中有机半导体本身的溶解度由光可逆电荷转移化学控制，从而实现了有机电子材料的衍射极限图案化，这一技术突破使得能够利用光对有机半导体或半导体内的掺杂水平进行图案化。研究团队将探索新型电荷转移掺杂剂的化学合成，以使该技术能够应用于更广泛的半导体，光学处理以减少写入时间和特征尺寸，以及化学处理以使每个顺序步骤与高光相一致。吞吐量卷对卷加工，其最终重点是开发具有掺杂有机电极、图案化栅极和高开关速度的全有机晶体管阵列，纳米制造工艺将利用学生实习和设备扩大到大面积。在帕洛阿尔托研究中心。
