About Aluvia Photonics

Aluvia Photonics is a leading pure-play foundry specializing in Aluminum Oxide (Al₂O₃)-based photonic integrated circuits (PICs). Our mission is to drive innovation in optical communication, sensing, and quantum applications by delivering high-performance photonic solutions. As we expand our capabilities, we are seeking a Development & Process Step Engineer to develop and optimize new fabrication processes, with a strong focus on sputter deposition for optical layers.

Job Overview

As a Development & Process Step Engineer, you will be responsible for the research, development, and optimization of new semiconductor fabrication processes. A key aspect of this role is developing and refining sputter deposition recipes for high-quality optical AlOx layers. You will collaborate closely with integration, process, and characterization teams to ensure that new processes meet performance, yield, and manufacturability requirements.

Key Responsibilities

  • Process Development: Design, develop, and optimize new semiconductor fabrication processes for photonic integrated circuits.

  • Sputter Deposition Recipe Development: Develop and refine sputter deposition recipes to achieve high-quality optical thin film layers with precise thickness, refractive index control, and minimal loss.

  • Materials & Optical Layer Engineering: Evaluate and optimize material properties for optical layer performance in photonic devices.

  • Process Characterization & Optimization: Utilize metrology tools such as ellipsometry, spectrophotometry, SEM, and AFM to assess deposition quality and refine process parameters.

  • Process Integration: Work with integration engineers to ensure compatibility of new processes with existing workflows and overall fabrication processes.

  • Troubleshooting & Continuous Improvement: Diagnose process issues, implement corrective actions, and drive continuous improvements in sputtering and other deposition processes.

  • Documentation & Standardization: Maintain detailed records of process development, create standard operating procedures (SOPs), and support knowledge transfer.

  • Collaboration & Communication: Work with multidisciplinary teams to align new process developments with production and R&D goals.

Qualifications & Skills

Required

  • Master’s or PhD in Materials Science, Electrical Engineering, Applied Physics, Nanotechnology, or a related field.

  • Hands-on experience in thin-film deposition processes, particularly sputter deposition.

  • Strong understanding of optical coatings, materials engineering, and photonic device fabrication.

  • Experience with process development in a semiconductor or photonics cleanroom environment.

  • Proficiency in using characterization tools such as ellipsometry, AFM, SEM, and spectrophotometry.

  • Strong analytical and problem-solving skills with a structured approach to process optimization.

  • Excellent documentation and reporting skills to ensure reproducibility and standardization.

  • Ability to work effectively in a cross-functional and fast-paced environment.

Preferred

  • Experience developing and scaling up deposition processes from R&D to production.

  • Familiarity with high-precision optical layer deposition for photonic applications.

  • Knowledge of statistical process control (SPC) and design of experiments (DOE).

  • Experience with automation and scripting for process monitoring and optimization.

What We Offer

  • An opportunity to work at the forefront of photonic integrated circuit technology.

  • Access to state-of-the-art deposition and characterization equipment.

  • A collaborative and dynamic work environment that fosters innovation.

  • Competitive salary and benefits package.

  • Career development opportunities in a rapidly expanding company.
