The desire for cost-effective strategies for producing organic electronic devices has led to many new methods for the organic semiconductor layer deposition; however, manufacturing contacts remains an expensive technique due to the high cost of both the materials used and the processing necessary for their patterning. In this work, we present a method for contact deposition and patterning, which overcomes these limitations and allows fabrication of all-printed organic thin-film transistors on paper. The method relies on depositing contacts using aerosol spray and patterning them with a digitally printed mask from an office laser printer, at ambient temperature and pressure. This technique, which we have denoted aerosol spray laser lithography, is cost-effective and extremely versatile in terms of material choice and electrode geometry. As the processing temperature does not exceed 155 °C, it is compatible with a variety of substrates, including plastic or paper. The success of this method marks an opportunity for a rapid, scalable, and low-cost alternative to current electrode-manufacturing techniques for development of flexible, large-area, electronic applications.

对用于生产有机电子器件的具有成本效益的策略的需求导致了用于有机半导体层沉积的许多新方法；因此，人们越来越多地采用这种方法。然而，由于所使用的材料和对其构图所必需的处理的高成本，制造接触件仍然是昂贵的技术。在这项工作中，我们提出了一种用于接触沉积和构图的方法，该方法克服了这些限制，并允许在纸上制造所有印刷的有机薄膜晶体管。该方法依赖于使用气溶胶喷雾沉积触点，并使用来自办公室激光打印机的数字印刷掩模在环境温度和压力下对触点进行构图。我们将这种技术称为气溶胶喷雾激光光刻技术，具有成本效益，并且在材料选择和电极几何形状方面极为灵活。由于处理温度不超过155°C，因此它可与包括塑料或纸张在内的多种基材兼容。该方法的成功为快速，可扩展且低成本的替代现有电极制造技术提供了机会，以开发灵活的，大面积的电子应用。
