ABSTRACT
Since the invention of organic light-emitting diodes (OLEDs) in the late 1980s, interest in organic materials has increased sharply. The ability to create large-area and mechanically flexible electronics with cost-effective manufacturing processes was attractive to many fields, such as the automotive and lighting industries. With the development of organic thin-film transistors (OTFTs) and organic photovoltaic cells (OPVCs), the range of potential applications expanded, to include smart buildings, biomedical implants, and the Internet of Things (IoT) to name a few.
On the other hand, important developments in traditional (inorganic) electronics took place. Advancements in thin-film devices, integration of hybrid systems on foils (HySiF), post processing of wafers and introduction of new materials paved the way for building mechanically flexible electronic systems based on silicon.
This tutorial introduces the large and interdisciplinary field of flexible electronics. The first part presents the fundamentals, including definitions, semiconductor types, devices and others. In the second part the focus lies on materials, and manufacturing processes for thin film transistors. The third part is dedicated to an overview on different organic thin-film transistors and a critical assessment of their strengths and weaknesses. Finally, the combination of CMOS and thin electronics in HySiF format are addressed.
