Process of surface modification of dielectric structures in organic electronic devices to increase surface energy

摘要

The invention relates to a process of modifying the surface energy of dielectric structures, like for example dielectric layers or bank structures, in organic electronic (OE) devices, more specifically in organic field effect transistors (OFETs).
