Dr. Michael Liehr
Michael's doctorate in physics originally focused on ion beam production from hot plasma sources . Later he developed microwave plasma reactors for diamond thin films deposition and PECVD processes for the deposition of organic and ceramic layers from metal organic pre-cursor material. He served as director of R&D at Applied Films GmbH and the managing director of Leybold Optics Dresden GmbH over a period of ten years.
Dr. Clemens Ringpfeil
Clemens was awarded his doctorate in surface physics for the x-ray diagnostics of thin films. Later, he was offered the position of R&D manager at Leybold Optics Dresden GmbH, where he gained valuable experience in process implementation of magnetron sputtering of metallic and ceramic layers on a range of conventional and special substrates for large scale production.
DR. CHANGHUI LI
Changhui obtained his doctorate from Max-Planck-Institut für Mikrostrukturtechnik in Halle, Germany, after having graduated with B.Sc. from the University of Science and Technology of China in Hefei, China, and with M.Sc. from the Institute of Physics of the Graduate University of Chinese Academy of Sciences in Bejing, China. Before relocating to Germany Changhui worked for various industrial companies in China and complements the expertise of W&L with in-depth knowledge of crystalline material properties.
Dieter started his career at AEG semiconductors after earning a degree in material science. He then joined Leybold AG.. During this time Dieter made magnetron sputtering a mainstream technology. Based on his wide experience in PVD Dieter became co-founder and managing director of SenVac GmbH, a company which excelled in implementing sputter targets with the special power supplies to the coating industry.
