在这项工作中，提出了一种凹印单极有机薄膜晶体管(OTFT)技术，能够获得最先进的成品率性能。印刷多层交联型介质以减少栅漏缺陷，栅漏缺陷已被发现是以前印刷OTFT的主要失效机制之一。在晶体管水平上进行的缺陷分析表明，在由6个连续箔制造的540个OTFT样品中，99.8%的器件是无缺陷的。利用改进后的工艺设计并制作了一种用于矩阵寻址应用的新型行驱动电路。所提出的8级行驱动器的实验表征表明，电路成品率高达100%，在5个连续的箔中超过15个样本，对应于2085个全功能OTFT的总数。与大规模生产兼容的印刷有机技术的可用性有望使具有极低生产成本特征的创新型物联网(IoT)应用成为可能。
In this work is presented a gravure-printed unipolar Organic Thin-Film Transistor (OTFT) technology able to achieve state-of-the-art yield performance. A multilayer cross-linked dielectric is printed to reduce gate-leakage defects, which have been found to be one of the main failure mechanisms in previous printed OTFTs. The defectivity analysis performed at transistor level reveals 99.8% defect-free devices in a sample of 540 OTFTs, manufactured on 6 successive foils. A novel row driver circuit for matrix-addressing applications has been designed and fabricated using the improved technology. The experimental characterization of the proposed 8-stage row drivers reveals a circuit yield as high as 100%, over 15 samples in 5 successive foils, corresponding to a total number of 2085 fully functional OTFTs. The availability of a printed organic technology compatible with mass production is expected to enable innovative Internet of Things (IoT) applications characterized by extremely low production cost.
