Internship / Bachelor & Master Thesis on Surface optimization and qualification


If you are still student or recently graduated willing to change the world with your innovative solutions you are in the correct place.


High purity components are essential to build the next generation semiconductor production tools. The current valve solution for gas management face limitations in stainless steel/elastomer surface roughnesses and qualification methods. To increase our product portfolio we are looking for an innovative student with excellent mechanical / machining / simulation skills. Interest for electro polishing is a plus. Task includes research and current world problems. We need to be flexible and adapt to the changes and come up with a new idea in a short time. Goal of the work is to evaluate the status of the surface polishing of the product, decide on the correct manufacturing method, and evaluate qualification methods and prototype building.  Your responsibility will cover the whole innovation process starting with the collection of ideas together with our R&D team, define and evaluate concepts, build a prototype and finally test the pressure control performance of the newly designed valve.
