Postdoctoral Researcher Superconducting qubits fabrication

What you will do

Imec is currently developing in its 300mm Si pilot line a process flow for superconducting qubit-based quantum computing. The extreme sensitivity of these qubits to the crystalline quality of the material, impurity and defects, interfaces and etch damage means that every step of the integration has the potential to reduce the qubit coherence time. During growth (deposition-related challenge) and during patterning (etch related challenge) bulk defectivity, junction interface defectivity or edge defectivity can appear. The precise relation between the nature of the defects and it impact on the coherence time is not known and is limiting the increase in performance of the qubit. Therefore, there is a need for a fundamental understanding of the interaction between growth, etch, defectivity and electrical performance of the superconducting qubits. In practice: -

  • You will be embedded in the thin film group, responsible for the growth of the Josephson junctions
  • You will strongly interact with the etch group, to develop the etch processes required to fabricate the Josephson junctions and resonators required to form qubit-based devices
  • Using imec’s extended characterization toolset, you will evaluate the fundamental links between material, process and qubit performances
  • You will develop innovative approach and enable new materials for the next generation of Josephson junctions

What we do for you

We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium. With your talent, passion and expertise, you’ll become part of a team that makes the impossible possible. Together, we shape the technology that will determine the society of tomorrow. We are proud of our open, multicultural, and informal working environment with ample possibilities to take initiative and show responsibility. We commit to supporting and guiding you in this process; not only with words but also with tangible actions. Through, 'our corporate university', we actively invest in your development to stimulate your technical and personal growth. We are aware that your valuable contribution makes imec a top player in its field. Your energy and commitment are therefore appreciated by means of a competitive salary with many fringe benefits.

Who you are

  • You have a PhD in physics, material science, nanotechnology or related field of science
  • You have experience with either Physical Vapor Deposition or Dry etch process development
  • You ideally have a first experience in superconducting qubits and Josephson junctions
  • You are an enthusiastic and motivated team player with good communication and reporting skill
  • You have an excellent knowledge of English.

This postdoctoral position is funded by imec through KU Leuven. Because of the specific financing statute which targets international mobility for postdocs, only candidates who did not stay or work/study in Belgium for more than 24 months in the past 3 years can be considered for the position (short stays such as holiday, participation in conferences, etc. are not taken into account).
