Dr. Arnd GreilingManaging Director (CEO)

The doctorate chemist is is an outstanding expert in the development of innovative material systems for III/V semiconductors. Dr. Greiling is responsible for technology, manufacturing and quality management and directs Dockweiler Chemicals as CEO with a focus on expansion in international businesses.

Dr. Greiling began his research on precursor chemistry during his studies and scientist work at the Philipps-Universität/Marburg. After completing his doctoral thesis on the topic of “Elementorganical Compounds of Arsenic – Alternative Sources for CVD” he set up a forerunner company and started the research project “development and synthesis of novel precursors for MOCVD” (in cooperation with Siemens and Alcatel). Within only two years of developing a complete new material system for semiconductor-production, his innovation was honored with the prestigious “Karl-Heinz-Beckurts Preis” award from the German Federal Ministry of Education, Science, Research and Technology.

Dr. Jörg KochManaging Director (CMO)

The doctorate physicist specializes in the design of novel precursor chemistry and its adaption to production using system technology. His expertise also includes the marketing of chemical products. Dr. Jörg Koch is responsible for sales & marketing, new business development and R&D.

Dr. Jörg Koch also began his career in science at the Structure and Technology Research Lab of Philipps-Universität/Marburg. The main focus of his research was in the deposition and analysis of semiconducting materials. In his later years he became specialized in the area of marketing, initially as manager in the Compound Semiconductor Division at Mochem, later as Technical Marketing Manager at Akzo Nobel, where he internationally launched several new products as well as joined development projects with customers to implement new technologies. The integration of new process technology in high tech industries has been getting a key aspect of Jörg’s activities. He is supporting this from the system technology in his role as Managing Director at SEMPA SYSTEMS GmbH.

Dr. Manuel KapiteinHead of R&D

The doctorate chemist is an outstanding expert in chemical synthesis. Dr. Kapitein is head of the R&D activities and novel product development.

Dr. Manuel Kapitein finished his B.Sc. in general chemistry in 2010 at the University of Marburg with a bachelor thesis focused on heavier Tin-Sulfur-compounds, followed by a M.Sc. based on material and inorganic chemistry. He graduated in 2012 in less than the standard period of study with excellent grades. Both, his master thesis as well as the subsequent PhD, were focused on main group metalorganic chemistry – the basis of modern CVD precursor design. His ambitions for material chemistry began with practical work on industrial polymers in the early bachelor studies and were concluded with a 2-year Post-Doc period at the University of Marburg, thematically focused on the optimization of pilot-plant scale precursor production as well as the development of new synthetic strategies. Manuel is head of R&D at Dockweiler Chemicals and is engaged in various projects designing and synthesizing novel, innovative precursor molecules.

Kai RonzheimerHead of Production

The chemical engineer has decades of experience in chemical manufacturing and 24/7 production processes. Kai Ronzheimer is responsible for all production-related activities.

The Philipps University laboratory technician is a state certified environmental protection engineer trained at the University for Environmental Technology in Frankenberg. His career started as the laboratory head at Mochem, out of which Dockweiler Chemicals later emerged. During the time the company belonged to Akzo Nobel, Kai Ronzheimer was head of the entire production. His expertise in the safe and sustainable manufacturing of high purity process-chemicals for CVD applications now spans several decades.

Prof. Carsten von Hänisch Scientific Advisor

Carsten von Hänisch studied chemistry under Professor Dieter Fenske at the University of Karlsruhe, where he received his Ph.D. on “Investigations on the coordination behaviour of polyarsenic compounds” in 1996. After a postdoctoral stay with Prof. Matthias Driess in Bochum, he returned to Karlsruhe in 1998 and completed his habilitation at the Institute of Nanotechnology at the Karlsruhe Research Center in 2005. In 2010, he was offered a professorship in function-oriented inorganic chemistry at the Philipps University of Marburg.

Prof. Dr. Kerstin VolzScientific Advisor

Prof. Kerstin Volz is a partner at Dockweiler Chemicals GmbH and has been a Heisenberg Professor of Experimental Physics and co-leader at the STRL (Structure and Technology Research Lab) of Philipps University Marburg since 2009. She received her diploma in physics from Augsburg University in 1996.

In 1999 she obtained her PhD from the same university. After several research visits at Osaka National Research Institute and Nagasaki Institute of Technology, as well as a postdoctoral stay at Stanford University, she joined Philipps-Universität Marburg as a Junior Group Leader (in the framework of a Topical Research Group of the DFG). After a professorship at the Humboldt-Universität of Berlin, she was appointed as a professor in Marburg and will serve there as speaker of the Research Training Group “Functionalization of Semiconductors” starting in 2012. She has received the following awards: Graduate Student Award of EMRS (1996); Feodor-Lynen scholarship of Alexander von Humboldt foundation (2001); guest professorship of Humboldt Universität of Berlin (2008); Heisenberg professorship of DFG (2008); and the Patricia Pahamy Prize for best teaching (2009). Her research interests include the synthesis (MOVPE) and quantitative transmission electron microscopy of novel functional materials.
