Besides the existing product portfolio of solution-processable semiconductor, dielectric and auxiliary material inks which allow to manufacture organic thin film transistors (OTFT) on flexible substrates in a cost-efficient way, BASF presents its new InkSet 1000SP package for fully structured transistors.
“InkSet 1000SP is a comprehensive package which includes inks for planarization, contact treatment, semiconductor, gate dielectric and interlayer dielectric, as well as a complete process description for their application. The inks and processes are perfectly adapted to each other,” said Dr. Jochen Brill, Head of R&D of BASF’s Field Effect Transistor team..
Along with the products, BASF is also showcasing demonstrators highlighting the benefits of flexible and lightweight electronics in various applications. The recent demonstrator built jointly by BASF and InnovationLab, Heidelberg, visualizes the opportunities for printed organic electronics in packaging. An interactive label is an example of a marketing tool for a brand owner that adds a unique feature for consumers..
Most parts of the demonstrator are printed – piezoresistive sensors and OTFTs – which means the fabrication is simple and cost efficient. The possibility to integrate printed circuits into continuous roll-to-roll processes, typical for label production, makes printed TFTs a solution of choice for the next generation of smart labels and packaging.
