“Inkjet Geometric Design Rules Generation and Characterization”

Inkjet printing is a challenging technique that will lead to a new paradigm in electronics fabrication through the construction of electronic devices and circuits drop by drop. However, inkjet technology for Printed Electronics is still under development and several challenges remain. While there is significant progress in the development of electronic devices, such as organic transistors, there is a lack of work on circuit and system level design. Designing devices and circuits requires a wide knowledge of process aspects and a complex interaction among concepts, tools and processes coming from different science and engineering disciplines. Our proposal is based on the experience of the silicon foundry model, and the idea of the process design kit (PDK) as the nexus between design and technology. PDK basic information contents are given in terms of geometrical and electrical design rules, device technology parameters and simulation models. A methodology to extract and characterize inkjet geometric Design Rules is proposed in this work as a first step to separate design from fabrication in a similar way as in silicon technology design, to develop devices and systems without a deep knowledge of process and materials. Geometric design rules aim to guarantee that layout representations match final printed patterns within a valid tolerance for a desired process yield. The more conservative the rules are, the better is the yield. Although they can comprise a very large set of restrictions, they are based on two considerations: (1) the geometrical patterns that can be reproduced by the process and (2) the interaction between different layers. So, for a given process and after an experimental extraction of the required process parameters, it is possible to derive minimum design rules that characterize the technology process to a point where design engineers can address physical design with sufficient certainty.
