- Resumen
In recent years, the interest in the manufacture of low-cost electronic systems has been on the rise due to increasing efforts of using sensors in Smart Cities and Industry 4.0. Multiple low-cost applications are beginning to appear, such as RFID stickers for product identification, flexible displays, or smart tags among others. Due to this need, Organic and Printed Electronics has positioned itself as an alternative technology to silicon with competitive advantages thanks to innovative materials and manufacturing methods in the world of electronics, allowing the production of low-cost, flexible, lightweight, large area and biodegradable devices. Despite this interest, there is still a lot of work to be done related to device modeling, design and simulation of complex circuits.
This thesis focus on the development of a Process Design Kit (PDK) with the necessary methodologies for the elaboration of an industrial model, which incorporates the DC and AC behavior of organic transistors, combined with the variations introduced by environmental factors and the intrinsic variability of the device. The PDK has been developed with a large automatic component, so it can evolve at the same time as the organic devices to be used.
Within the framework of the thesis, an automatic electrical characterization environment has been developed with an output that provides the reports of devices and models allowing the analysis of a large number of transistors and their parameters. At the same time, a study of how it is affected by different external factors such as light, humidity or temperature, and the incidence of the application over and over again of potentials in the terminals has been done. The physical design part of the PDK is based on a set of Parameterized Cells (PCells), made in such a way that they are correct by design and combined with automatic methods allow the generation of arrays of devices and circuits in a reduced time. Multiple different devices and circuits have been made following this methodology in order to be able for characterization and modeling using the tools developed in the PDK.
The results of this thesis have allowed applying the knowledge in two different manufacturers of organic devices with the aim of design flexible systems. One of the great achievements of this thesis is the simulation and design of a 16-bit RFID tag developed by using organic technology and based on the methods developed and implemented in the developed PDK. On the other hand, the implemented tool allows following the evolution of the devices without a greater intervention on it, allowing advancing with new devices, creating and parameterizing models without great efforts.
