Self-Aligned Process To Manufacture Organic Transistors

摘要

Semiconducting device and method of manufacturing a semiconducting device in which organic thin film transistors (TFTs) and other components are fabricated on a substrate ( 206 ), using a hybrid technology of lithographic and printing steps. A lithographically defined resist pattern ( 211, 311 ) provides barriers and cavities which serve to guide subsequently printed materials. Different components of the integrated circuitry form separate islands on the substrate ( 206 ). The risk of adjacent films cracking and peeling from stress is reduced. The flexibility of the device is increased.
