Organic electronics:
manufacturing technology of the 2. generation*

Today, photolithography is widely used to pattern conductive materials with resolutions on the micron scale. For mass-produced and low-cost applications like polymer electronics, photolithography is too costly and time-consuming. Mass-printing techniques are fast, but do not reach the required resolution.

Our electrochemical approach for patterning of conductive polymers closes the gap:

• Fast, additive, and scalable process for flexible substrates
• no specific formulation of the conductive polymers as a printing ink is required, no spreading and moistening problems during the process
• Higher conductivities than conventionally printed polymer inks, the patented process is applicable for nearly/almost all conductive polymers
• Planar surface topography simplifies further processing

During electrochemical polymerization, the dissolved monomers form the polymer pattern within seconds, precisely replicating the master. It is then embedded into the substrate foil and released from the master. Currently, the process is being automated and extended for flex-pcb applications.

This innovation is one of the patent portfolios that was chosen for a patent value fund* and now has been further developed and subsequently commercialized as part of a processing strategy by IPB.
