Reverse‐offset printing is capable of ultrafine printing at the submicron scale and may be applied to the fabrication process of electronic devices. In this study, the composition of Ag nanoparticle ink is investigated suitable for reverse‐offset printing using Ag nanoparticles synthesized by a thermal decomposition method via oxalate‐bridging silver alkylamine complexes. The suitability of Ag nanoparticle ink for the blanket is considered while focusing on the absorption characteristics, wettability, and drying properties. Using the synthesized Ag nanoparticle ink, the reverse‐offset printing conditions are optimized, successfully forming submicron‐scale ultrafine patterns. The successful fabrication of fully printed organic thin‐film transistors (TFTs) is also achieved with a significantly short (1 µm) channel using reverse‐offset printing. A maximum mobility of 1.25 cm2 Vs−1 at an operating voltage of less than 5 V is achieved in the printed organic TFT with a 5‐µm channel.

用于高分辨率印刷电极和采用反向胶印的有机薄膜晶体管的 Ag 纳米粒子油墨


反向胶印能够进行亚微米级的超精细印刷，可应用于电子设备的制造过程。在这项研究中，研究了 Ag 纳米颗粒墨水的成分，该油墨适用于使用通过草酸盐桥接银烷胺络合物的热分解方法合成的 Ag 纳米颗粒。在考虑 Ag 纳米粒子墨水对毯子的适用性的同时，还考虑了吸收特性、润湿性和干燥性能。使用合成的 Ag 纳米颗粒墨水，优化了反向胶印条件，成功形成亚微米级超细图案。使用反向胶印的极短 （1 μm） 通道也成功制造了全印刷的有机薄膜晶体管 （TFT）。在小于 5 V 的工作电压下，在具有 5μm 通道的印刷有机 TFT 中实现了 1.25 cm2 Vs−1 的最大迁移率。
