印刷/有机电子(PE)是一项具有巨大市场潜力的新兴技术，特别是如果它的实现是低成本的，并且与其设计相关的供应链是可管理的/建立的。对于前者，需要全加全空气低温工艺(相对于减法工艺)，而对于后者，需要一个用于电子设计自动化工具的综合工艺开发工具包(PDK)。在这篇文章中，我们描述了可以说是有史以来第一个用于PE的PDK-这种PDK是为我们的全添加全空气低温印刷工艺开发的，具有极低的工艺变化，能够在各种基板上完成电路实现，包括低成本的低温柔性塑料薄膜。我们提出的PDK体现了印刷晶体管和印刷无源元件的精确建模。利用这些模型，可以进行全面的原理图模拟，包括蒙特卡罗模拟。我们证明了我们的PDK的有效性，部分是基于我们测量的过程变化。我们的全添加印刷工艺的布局设计规则也在此勾勒出来，以促进布局设计--估计印刷面积和印刷成本的必要条件。
Printed/Organic Electronics (PE) is an emerging technology with gargantuan market potential, particularly if its realization is low cost and the supply chain associated with its design is manageable/established. For the former, a Fully-Additive All-Air Low-Temperature process (vis-à-vis a Subtractive process) is desirable, while for the latter, a comprehensive Process Development Kit (PDK) for Electronic Design Automation tools is necessary. In this paper, we delineate, arguably the first-ever PDK for PE — this PDK is developed for our Fully-Additive All-Air Low-Temperature printing process with very-low process variations, and capable of complete circuit realizations on a myriad of substrates, including low-cost low-temperature flexible plastic films. Our proposed PDK embodies accurate modeling of the printed transistor and printed passive elements. With these models, comprehensive schematic simulations can be performed, including Monte Carlo simulations. We demonstrate the efficacy of our PDK, in part based on our measured process variations. The layout design rules for our Fully-Additive printing process to facilitate layout design — imperative for estimating the printing area and the printing cost — are also delineated herein.
