Printed Electronics

Printed electronics is an emerging technology to create electrical devices on various substrates using printing methods. High-throughput printing methods such as screen printing, flexography, gravure, inkjet, and aerosol-jet methods can be used to deposit functional inks of conductors, insulators, and semiconductors creating active (thin film transistors (TFTs); memory elements; sensors), or passive devices (resistors; coils; protective coatings).

Our Laboratory contributes to the Coating Competence Center with a specific research focus on:

 

  • high-resolution digital printing methods including ink-jet, dispensing, and aerosol-jet printing;
  • photonic sintering of various printed structures and layers (semiconductors, conductors, dielectrics, ceramics) using flash-lamp annealing (photonic curing), deep-UV annealing (DUV), rapid-thermal processing (RTP).
  • oxide-based conductors (e.g. printed ITO), insulators (e.g. Al2O3-, SiO2-based), and semiconductors (e.g. IGZO) for demonstrating printed TFTs, Schottky diodes, security tags, and sensors;
  • printable protective coatings, e.g. for watch manufacturing;
  • new interconnection concepts for photovoltaic modules.
