In the past few decades, the field of flexible organic/polymeric electronics has advanced significantly. This has been primarily because of improvements in the quality organic/polymeric materials after processing, as well as the processing techniques and technologies. For example, roll-to-roll, sheet-to-sheet or printing technologies are being proposed as suitable manufacturing candidates because they can be carried out at room temperature, do not require the kind of clean room environment needed for traditional semiconductor manufacturing, and are very suitable for very low-cost, high volume production. Further, these advances are mostly stimulated by the promise of lighter and more robust devices and systems for applications that include large-area electronics, active matrix large-area displays, large-area solar cells, interactive displays, and conformable sensors and actuators. However, despite these advances, there remain challenges in the large-scale transfer of research prototypes into manufactured products. One of major the limitations is the lack of accurate compact models for organic/polymeric thin film transistors with associated parameter extraction techniques. In this presentation, we will discuss some of the recent compact models and illustrate the merits and limitations of several of them. We will discuss in detail our progress in developing industry-viable static and dynamic compact models for flexible transistors with predictable performance. Finally, we will present several modeling challenges including hysteresis and contacts effects, as well as models that can predict stability, reliability, and lifetime.
