Dr. Arnd GreilingManaging Director (CEO)

The doctorate chemist 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

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. Oliver BrielDirector Business Development

Oliver is a PhD in inorganic and organometallic chemistry and has been a versatile thought leader in the chemical industry for 20 years. At Dockweiler Chemicals, he is responsible for the strategic development of business areas and sales markets as Director of Business Development.

His professional positions range from R&D and applied technology, to marketing and business development, to supporting the homogeneous catalyst operations of a multinational precious metals company. For ten years he led an incubator program at Umicore for advanced electronic precursors for thin film applications. The objective was to build an integrated European manufacturer and supplier of innovative metal-based ALD and CVD precursors and related services for the electronics industry. With his team of experts, he managed the research and development and took it beyond the pilot phase to a level of maturity with investments in large-scale facilities for the commercial supply of high-purity precursors.

Oliver is the author of several technical publications and patents. He draws his energy from his enthusiasm for the technology and his creative and innovative approach to solving technical challenges that support the development of new application areas for organometallic and inorganic thin film deposition chemistry.

Carsten SchuckenböhmerChief Financial Officer

As an economist, Carsten is influenced by the spirit of the free trade philosophy of the Kiel Institute for the World Economy.

His professional experience results from auditing and consulting projects as well as management functions with a cross-industry focus.

At Dockweiler Chemicals, Carsten is responsible for all commercial matters, i.e. finance and accounting, controlling, planning, purchasing, sales, human resources and other supporting functions.
He started his career in auditing at KPMG Hamburg, where he got to know various business models from the inside and operationally managed audit-, fraud-, due diligence- and consulting projects.
He then took on management roles at Razorfish (CFO, Digital Services, Germany), Schwab group (VP Finance, Mail Order/E-Commerce), Ihle Group (CFO, Automotive) and in the Optical Industry (MD).

In addition, he supported management and shareholders of medium-sized companies as advisor and business expert until he joined the company.

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.

Dr. Susanne Herritsch Head of Technology

The doctorate chemist specializes in metalorganic synthesis and upscaling new products to pilot plant scale. At Dockweiler Chemicals, she is responsible for the technology area and project management.

Dr. Susanne Herritsch studied chemistry at Philipps University in Marburg. Both the bachelor and the master thesis focused on the design of novel metalorganic products. She received her doctorate in 2018 in the field of metalorganic materials for CVD and ALD applications. The focus of her dissertation was the design and the development of novel volatile precursors based on nitrogen-containing ligands. In addition, Susanne has investigated industrial upscaling options and the synthesis optimization of established CVD and ALD chemicals in various funded projects. After her PhD, she gained experiences in the photovoltaic plant engineering as well as in the management of development and investment projects.

At Dockweiler Chemicals, Susanne is Head of Technology and drives forward the upscaling of newly developed and innovative materials on large scale production under consideration of optimized processes.

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. 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.
