Cleanroom Fabrication Engineer at the Quantum Device Lab

About the job

Cleanroom Fabrication Engineer at the Quantum Device Lab

At the Quantum Device Lab , led by Prof. Andreas Wallraff at the Department of Physics of ETH Zurich, we fabricate quantum devices using micro- and nanofabrication techniques. We use the devices to conduct state-of-the-art experimental research in quantum information science and technology. In particular, we work on scaling the developed technologies to build large-scale error-corrected quantum computers. We operate across various cleanrooms in the Zurich area, and develop new technology and approaches which benefit from a coherent, farsighted vision. We collaborate closely with academic and industrial partners within the quantum community.

Project background

We are looking for a Cleanroom Fabrication Engineer to join our interdisciplinary team doing research and development at the forefront of quantum technologies. You will play a crucial role in the development of quantum processor chips, working on devices that incorporate tens to hundreds of qubits. A primary goal of work will be the scaling of micro-fabricated chips, including the development of Through-Silicon-Vias (TSVs), connecting the front to back surface of the chips with high-quality superconducting films. These will reduce the impact of parasitic box modes, and enable alternative signal routing paths, enabling the scaling up in device size.

Job description

Your responsibilities will include: 

• Device fabrication: Execution and refinement of micro and nano-fabrication runs using existing fabrication processes.
• Process development: Development and optimization of novel fabrication processes for scalable architectures (such as high-aspect-ratio TSVs deep reactive-ion etching and conformal coating).
• Yield improvement: Systematic metrology inspection to continuously improve fabrication yield.
• High-coherence compatibility: Collaboration with other fabrication engineers of the lab and the measurement researchers to evaluate impact of processes on qubit coherence metrics, and guarantee high-quality device outputs.
• Documentation: Preparation of technical and scientific documentation of your work. Tracking of run logs and process metrics shared with scientists from the Quantum Device Lab who have the lead in characterizing and operating the fabricated devices.

Profile

We are looking for a highly motivated fabrication engineer to lead the fabrication and process development of devices that advance our capabilities in large-scale quantum computing.

Candidates must have experience in an academic and/or industrial setting in a number of the following areas:

• Hands-on cleanroom experience: Proven record with semi- or superconductor processing techniques, such as electron beam lithography, photolithography, dry and wet etching, thin film deposition
• Process control: surface characterization, metrology (optical-, scanning-electron microscopy, atomic force microscopy), material science, statistical process control, yield improvement, failure analysis.
• Specialized equipment: practical technical knowledge of vacuum technology, (pumps, UHV systems, ...), leak detection, or cryogenic systems.
• Research experience: ability to demonstrate high-quality reporting examples.

Further Requirements:

• You are expected to be skilled in communicating your findings to collaborators in a multidisciplinary environment. You should have high attention to details, structured work habits, and the ability to handle complex workflows.
• You must hold a Master degree or equivalent in micro- and nanofabrication, material science, physics, electrical engineering or a related field. A PhD degree can be helpful but is not required.
• You must possess excellent English communication skills; knowledge of German is a plus.

We offer

• In depth exposure the rapidly developing field of quantum technology, and opportunity to tackle a wide range of fabrication challenges, combined with ample learning opportunities.
• A collaborative, interdisciplinary R&D environment. A rewarding, inspiring working environment with a flat hierarchy and open culture in a diverse and international team.
• Access to state-of-the-art cleanroom fabrication facilities located at  ETH Hönggerberg (FIRST), at  IBM Rüschlikon (BRNC) and at  PSI Villigen (PICO).
