The Role
The role involves leading process development in MicroLED and Optical Computing, optimizing semiconductor fabrication processes, and collaborating on innovations and tool specifications.
Summary Generated by Built In
Join a fast-growing Process Development team pushing the boundaries of innovation in MicroLED and Optical Computing. Around 60% of your time will be spent in a state-of-the-art cleanroom advancing process development, and the other 40% on planning, analysing data, and presenting insights to management.
Key Responsibilities
- You will work on all stages of process development, defining process architecture, developing process modules, working with process development tool owners to develop and optimise pixel performance.
- Constantly seek out and implement opportunities for innovation and improvement in the products and processes.
- Participate in risk assessments and design reviews.
- Identify the requirements for new tooling to support the MicroLED and Optical Compute development roadmap, including defining process recipe specifications and aligning with the process tool owner.
- Leverage your R&D and process development experience to drive progress within a high-performing, results-oriented team.
Skills, Knowledge and Expertise
- A PhD in Physics, Electrical/Electronic Engineering, Materials Science, or a related discipline focused on III–V semiconductor devices, or a bachelor’s degree with at least three years of relevant industry experience.
- Hands on experience of developing and optimising III- V, ideally III – N, semiconductor device fabrication processes in a clean room environment.
- Knowledge of semiconductor device physics.
- Broad experience in semiconductor process techniques, including but not limited to lithography (stepper and mask aligner), etch (RIE, ICP and wet etch), CVD, PVD, Evaporation, ALD, IBD.
- Design of Experiments and statistical analysis techniques.
- Working knowledge of CAM systems and SPC.
- Ability to communicate clearly, design decisions to cross-functional teams
- Experience of risk analysis and design review processes
- Experience with JMP or Python for data analysis would be an advantage.
- Understanding of LED and or Optical performance matrix and its measurement techniques such as IV response, Electroluminescence, EQE will be advantageous.
