Flexible amorphous oxide semiconductor thin-film transistors are viewed as an important technology
for a broad range of emerging electronic applications. Today, the long-held dream of rollable and
foldable displays is driving this innovation, but it is without a doubt that as the technology matures,
other applications will be realized. For example, curved X-ray detectors and other medical devices
such as skin patches, and wireless nfc playing cards, disposable food and medication sensor packages.
This presentation introduces the materials and processes required to fabricate amorphous oxide
transistors on plastic foils, offering advantages in terms of process simplification and device
performance. I will explain why a better understanding of these materials and devices – in terms of
possibilities and limitations - is needed in order for them to be used in next-generation mobile and
wearable electronics, focusing on both electrical as well as mechanical aspects. I will show examples
how the development new fabrication processes enable new amorphous oxide semiconductor
materials and novel device concepts.
