Microfabrication Engineer / Microfabrication Engineeress

Job Opportunity: Process Engineer at IDQuantique

At IDQuantique, we are dedicated to developing the world’s highest-performing quantum computers. Our cutting-edge full-stack technology, based around trapped-ion qubits, encompasses a diverse range of components including custom compilers, embedded firmware, mixed-signal and RF electronics, cryogenics, vacuum systems, and lasers. This technology is meticulously designed, manufactured, and operated by our leading scientists and engineers located in the UK, the US, and Switzerland.

We are excited to expand our microfabrication team by including a full-time Process Engineer who will work in the CMi cleanrooms, ideally based in or close to Lausanne, Switzerland.

This role is primarily hands-on and technical, involving the manufacturing of ion trap chips, which are crucial to our quantum computers. The chips comprise multiple, interconnected layers of patterned metal with oxide separation, along with integrated SiN photonic layers. They are fully manufacturable at the CMi cleanroom facility, and we also engage in collaborations with external partners. The successful candidate will have the opportunity to maintain and advance existing collaborations while exploring new partnerships and initiating relevant projects.

In addition to producing functioning ion traps, you will engage in process development to enhance yield, meet stringent tolerances, and explore and implement new designs and functionalities.

As the sole member of the microfabrication team based full-time in Switzerland, you will receive support and in-person contact from existing process engineers at least 30% of the time, along with online access to the entire company whenever needed. You will be a vital and valued contributor to a passionate and highly motivated company culture.

• End-to-end fabrication of ion trap chips
• Design effective process flow and successfully execute fabrication runs
• Accurate estimation of delivery timelines
• Maintain detailed wafer history runcards
• Track material and process data
• Contribute to process development by designing and executing experiments
• Document findings through comprehensive reports
• Maintain and advance collaborations with external partners

Requirements

• 3+ years of experience with standard semiconductor processing
• Proficiency in 2D layout design (e.g., Klayout software)
• Experience with laser and photolithography
• Knowledge of thin film deposition
• Experience with wet and dry etching
• Familiarity with metrology techniques such as SEM and profilometry
• Excellent communication and organizational skills
• Ability to work independently
• Comfort in environments with requirement uncertainty and constantly evolving information

Desirable Experience

• Experience with e-beam lithography, particularly for photonic structures
