Conferences and exhibitions

The OIC conference, which takes place every three years, is considered the most important conference in the field of optical interference coatings. At the conference, the latest findings and advances from science and research are presented and exchanged. This year, the OIC will cover all aspects of optical coatings, including fundamental research on coating design theory, materials, coating methods, characterization technologies, and applications in electronic displays, optical communications, high-power and ultrafast lasers, sensors, solar cells, low-emissivity coatings, optical instrumentation, and space.

The informative lectures at the conference will be complemented by a program of short courses, an exhibition and a special evening presentation. The Fraunhofer IST is participating in this year's conference with a short course and several lectures:

”Process concepts of magnetron sputtering for optical functional coatings”

Dr. Michael Vergöhl (Short Course SC399)

Sputtering is one of the most important technologies for large area applications and optical technologies. A wide range of products can be fabricated, from large area low-E coatings to ultra-precise filters with more than 1000 layers. Short Course participants will become familiar with the various process concepts of magnetron sputtering as they are used today in the development and fabrication of optical coatings. The course will discuss the magnetron sputtering process in detail. It will address how it can handle instabilities in the process, and how it can control uniformities, particle contamination, or specific layer properties in the deposition process. The focus of the course lies on deposition processes for optical coatings and how they relate plasma properties to relevant layer properties such as roughness, density, or optical losses.

After a brief introduction to the physics of sputtering, magnetron discharge and transport of particles through the gas phase, and the introduction of the magnetron cathode for sputtering, the focus will then lie on reactive magnetron sputtering. The second application-oriented part of the course focuses on application-related layer properties obtained by reactive magnetron sputtering.
