Research engineer position – development of TSV nano-process for quantum computing

Reference number REF 2024-0207

We invite applications for a research engineer position at Chalmers University of Technology, focused on nano fabrication for quantum processors. At Chalmers we are at the forefront of quantum technology. We are part of WACQT, which is the largest national effort in Sweden on quantum technology. We are also part of the European Project OpenSuperQ+ that is a large collaboration between European universities and research institutes in quantum technology. This position concerns silicon microfabrication for quantum processors. The position is for 1 year and desired starting date is latest June 2024.

Information about the division and the department
In the Department of Microtechnology and Nanoscience, MC2, state-of-the art research in various fields such as micro-electronics, photonics, microwave techniques and quantum technology are being conducted. The department features a 1500 square meter clean room with all equipment needed for micro- and nanofabrication as well as many labs for characterization.

The Quantum Technology, QT, division is an experimental group working that is developing several aspects of quantum technology. The division focuses on superconducting quantum phenomena and routinely fabricates high-quality qubits and novel qubit architectures. We use a flip-chip technology for building our large size quantum processors (QPUs). To continue to develop that technology we need to add also through-silicon vias (TSVs) to our technology stack, and aim is to develop that process within this position.

Major responsibilities
In this role, you will actively contribute to the development of the next generation QPUs. You will contribute to the goals in the WACQT project. Your main tasks will be nano fabrication in the MC2 clean room. You will work closely with other engineers and researchers working on the QPU fabrication. Your tasks will include standard clean room processing, participation in the groups weekly fabrication meetings and discussing fab processes. You will be the main responsible for developing a TSV process suitable for QT and affiliated entities. This includes creating holes for the vias as well as metallization of superconducting metals. A successful project will also be able to characterize the TSVs under cryogenic conditions and potentially in combination with qubits and other superconducting structures. Your results will be used by colleges to manufacture the full QPU chips and is crucial for us to scale up our efforts to larger qubit counts in our QPUs.

To be considered, you should have at least an MSc in a relevant field and experience in micro- and nanofabrication. Good knowledge of cryogenics is meriting. Good knowledge of micro- and nanofabrication is required. If you have prior experience from working in one of the MyFab cleanrooms, it is meriting. Previous experience with silicon process development, deep reactive ion etching (DRIE) is meriting. Experience from MEMS processing is meriting. Good understanding of electrical characterization and microwave measurements is meriting.

Contract terms
This position is a full-time temporary employment for 1 year.
