UV LED Technologies & Application

April 22-25, 2018 · Berlin, Germany

Technical Tours/Visits on April 25, 2018

Berlin is among the largest and most diverse regions for science in Europe and has the greatest concentration of university and institutional research facilities in Germany. Thus, the German capital region provides top conditions for innovation and growth. This is particularly positive for the innovative growth sectors and future fields that are combined in five capital region clusters, including Photonics.

Nearly 400 technology companies and more than 30 university and non-university scientific institutes research and develop high-tech components, systems and products in Berlin for the world market. With its wide range of expertise, the capital region has become one of the world's leading locations for photonics and microsystems technologies.

Use the opportunity to visit a company or research institution in and nearby Berlin on April 25, 2018.

Charité - Universitätsmedizin Berlin, Center of Experimental and Applied Cutaneous Physiology

Physical method for the non-invasive determination of the sun protection factor of sunscreens by LED techniques

An experimental method for the determination of the sun protection factor of sunscreen is developed at the Center of Experimental and Applied Cutaneous Physiology (CCP) at Charité – Universitätsmedizin Berlin. The measurements are not based on the development of a sunburn as biological response of the skin to sun radiation. They will be carried out in vivo on volunteers by reflectance spectroscopy.

CrysTec GmbH

Single crystal processing for electronics research

CrysTec GmbH is a worldwide leading manufacturer of oxidic and fluoridic substrate materials for oxide electronics research market (ferroelectrics, multiferroics, superconductors, topological insulators etc.). CrysTec is engaged in development of Nitride substrates like AlN for UV application. On CrysTec tour you will get an overview about substrates manufacturing cycle, which are still at an early stage for an expected industrial use. You will get an imagination, what else exists next to the important materials like silicon, GaAs, SiC and sapphire, which are the key materials for the today´s electronics.

Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik

Fabrication of UV LEDs – semiconductor epitaxy and chip processing

The tour covers two main segments of the process chain for the fabrication of UV LEDs. You will visit the lab where the semiconductor crystal layer structures are grown on substrate wafers using metalorganic vapor phase epitaxy. Moreover, the cleanroom for the frontend processing of these wafers will be shown which involves chip processing technologies such as photolithography or plasma etching.

Technische Universität Berlin – Institute of Solid State Physics

Deep UV LED fabrication and testing at Technische Universität Berlin

At the lab for Experimental Nanophysics and Photonics in the Technische Universität Berlin the crystalline layer structure of LEDs is grown, LEDs are fabricated and tested. We will explain the working principle of the UV LEDs, show the systems to grow the crystalline layers, and explain the fabrication procedure from the semiconductor wafer to the LED chips. Finally we will visit the lab for electroluminescence testing and show how we acquire emission power, spectrum and the far-field of the LEDs.
