Evonik and Holst Centre introduce iXsenic technology into mass production

The research of Evonik and Holst Centre has now resulted in an introduction to mass production for the iXsenic technology

Evonik Industries AG from Essen, Germany, a leading producer of specialty chemicals, and Holst Centre, an independent R&D centre for flexible electronics in Eindhoven, The Netherlands, have entered the next phase of their cooperation. Over the last two years, the partners have optimised the materials and processes of the new semiconductor technology iXsenic S. Now, the revolutionary technology has been introduced into mass production.

iXsenic S is a solution-processable inorganic metal oxide semiconductor, which is applied by slot-die coating. No vacuum environment is necessary, which is reported to result in process simplifications, outstandingly high yield and cost advantages. Applications areas include high-resolution LCDs and OLED displays, with or without flexible properties.

One of Evonik’s key customers will use the iXsenic S material combined with the well-established slot-die (slit) coating process in one of its sites. This will be facilitated by Holst Centre and supported on-site in Asia in Evonik’s recently inaugurated Application Technology Center.

“Evonik has the best n-type soluble oxide semiconductors in the world,” claims Gerwin Gelinck, organic and oxide transistors programme manager at Holst Centre. “We were able to demonstrate charge carrier mobilities exceeding 10 cm2/Vs in a reliable process uniformly on large areas with an iXsenic S. This state-of-the-art material and process will now be introduced into mass production, which could be the beginning of a new era in display manufacturing.”
