Description
About the Role
This role focuses on leading contamination control and manufacturing process development for deep-ultraviolet (DUV) laser systems. It requires strong expertise in photochemistry, surface chemistry, and contamination mechanisms that affect performance, reliability, and system lifetime. The position involves diagnosing and mitigating chemically driven degradation in high-energy UV environments and contributing to materials selection and long-term system reliability.
Responsibilities- Lead contamination control strategies for DUV laser manufacturing
- Analyze and mitigate photochemical and surface-driven degradation affecting optics, coatings, crystals, and related materials
- Evaluate and select materials such as polymers, metals, adhesives, coatings, solvents, and cleaning agents for DUV compatibility
- Develop and qualify cleaning, passivation, and handling processes based on chemical and surface‑science principles
- Conduct root‑cause analysis of DUV‑induced failures and contamination‑related issues
- Model and experimentally validate contamination transport, adsorption/desorption, and photo‑induced reactions in DUV environments
- Collaborate with R&D teams to transition laboratory‑scale solutions into manufacturing processes
- Define contamination‑control specifications, cleanliness standards, and acceptance criteria
- Support supplier qualification, engagement, and audits related to material compatibility and chemical cleanliness
- Mentor junior engineers and provide subject‑matter expertise in DUV contamination control and chemistry
- Advanced degree in Chemistry, Chemical Engineering, Materials Science, or a related field
- Strong understanding of photochemistry, surface chemistry, and molecular contamination under deep‑UV irradiation
- Proven experience resolving contamination‑driven performance or lifetime issues in optical or laser systems
- Knowledge of organic and inorganic contamination sources, out gassing, adsorption/desorption, and UV‑induced chemical reactions
- Experience working in contamination‑sensitive environments such as clean rooms or precision optics manufacturing
- Familiarity with cleaning processes, contamination‑control methods, and handling procedures for optical and laser components
- Hands‑on experience with DUV systems operating at 266 nm or shorter wavelengths in manufacturing, process engineering, or applied research
- Strong analytical and problem‑solving skills, with the ability to connect chemical mechanisms to system‑level behavior
- Experience with Failure Mode and Effects Analysis (FMEA)
- Experience using surface‑analysis and contamination‑diagnostics tools
- Proficiency in Statistical Process Control (SPC) methodologies and statistical analysis software
- Background in reliability engineering for DUV optical systems
- Experience defining cleanliness standards for high‑energy UV or photolithography‑related applications
