Quantum Chemical Engineer


Our research is focused on the development of new hybrid semiconductor-superconductor platforms to enable the application of Majorana bound states for topological quantum computing.

Material science and fabrication are the foundation and the enablers of qubit devices. Our client deals with complex stacks of different materials combined at the nanoscale and require state-of-the art metrology and in-depth morphological, structural and compositional analysis. Fabrication of qubit devices is a challenging, multi-step process pushing the boundaries of nanotechnology and nano-patterning techniques.

You can play a key role in the development of our ground-breaking approach to quantum computing by helping to realize quantum devices with quality and control well beyond the current state of the art.

One of the main processes to fabricated devices is to use wet and dry (reactive) etch processes in a top-down process. In addition, the devices need to be free of organic residues for which processes based on oxygen-plasma and nitric acid cleaning needs to be optimized.  We are looking for an engineer with a chemistry background to set-up and maintain the wet and dry (reactive) etch processes.


  • Develop and maintain wet and/or dry-etch process for metals (Al, Au, Nb, Pb) and semiconductors (InSb and InAs).
  • Optimize device/substrate cleanliness with Acetone/NMP, nitric acid and oxygen plasma.
  • Inspection of results by AFM, SEM, stepper, and optical microscope.
  • Priority of tasks and time spent
  • Setting up wet and dry etch processes – quality evaluation feedback loop.
  • Interaction with Kavli Nanolab clean room staff for the machine’s status/maintenance.
  • Communicating the status of the machines, processes stability and films quality to other team members.

Position Requirements/Qualifications

  • Bachelor / Master’s in Chemistry, Chemical engineering, or related disciplines, eg Physics, Material Science
  • In depth knowledge and direct experience (at least 2 years) in wet chemical process development/engineering for semiconductor fabrication, eg.
  1. Resist stripping, removal processes
  2. Silicon Oxide/Nitride etching
  3. Cleaning Technology
  4. Chemicals and Equipment (eg bench, spray)
  • Experience in metrology methods, such as: Optical, SEM, Chemical analytical methods for contamination control
  • Preferably experience in Knowledge of III-V materials and high-k dielectrics.
  • Preferably experience with design for six sigma (DFSS), design of experiment (DoE).
  • Ability to quickly integrate and work in a multi-disciplinary, international team and effectively collaborate and communicate to meet the deadlines and deliver against program goals

Our client offers excellent working conditions including competitive salary and the chance to work in a truly international environment.
