About the role
AI summarisedThis Senior/Staff position owns the end-to-end facet coating process for laser devices, managing everything from design and R&D to high-volume manufacturing. The role involves overseeing subcontractor operations, designing complex multilayer interference coatings, and implementing robust Statistical Process Control to ensure high yield and reliability for optoelectronic devices.
FablessOnsite
Key Responsibilities
- Lead the technical management and decision making for facet coating and related backend operations, including wafer scribing, laser bar handling, and Automated Visual Inspection (AVI).
- Design complex multilayer interference coatings (AR, HR, and passivation layers) and develop/optimize deposition recipes using IBS (Ion Beam Sputtering)
- Utilize spectroscopic ellipsometry, spectrophotometry, and AFM to verify film thickness, refractive index, and surface roughness
- Act as the primary technical point of contact for equipment suppliers; defining requirements for new tool acquisitions and engineering upgrades.
- Manage subcontractor manufacturers across different regions, implementing remote monitoring to ensure consistent performance across all coating processes.
- Drive New Process Integration (NPI) and formal process transfers from the design phase to high-volume manufacturing.
- Perform deep-dive root cause analysis and implement robust Corrective and Preventive Actions (CAPA) for any process excursions and eliminate sources of defects.
- Define comprehensive process control plans, Statistical Process Control (SPC) strategies, FMEA and Out-of-Control Action Plan (OCAP) execution.
- Establish dashboards and KPIs to track the health of facet coating processes; monitor daily performance and cycle time.
Requirements
- Bachelor’s or Master’s in Engineering (Physics, Materials Science, Optical, Chemical or Electrical Engineering).
- 5–15 years of experience in semiconductor wafer fab or backend processes.
- At least 5 years of hands-on experience in thin-film deposition specifically for optoelectronic devices
- Understanding of vacuum physics and deposition techniques (IBS, ALD)
- Knowledge of dielectric coating materials (e.g., Al2O3, SiO2, Ta2O5, TiO2, Si3N4 )
- Strong statistics fundamentals and knowledge of SPC, DOE, FMEA, DMAIC, and advanced statistical tools such as JMP, Tableau, or SQL
- Experience with automated bar-handling, wafer scribing and cleaving, Pick-and-Place (PnP), and AVI tools.
- Strong knowledge of laser (DFB, EML & VCSEL) manufacturing principles using InP (Indium Phosphide) and GaAs (Gallium Arsenide) materials
- Experience with Burn-in and fundamental mechanical engineering concepts.
- JMP Scripting and programming skills for data analysis and reporting automations
- Energetic leader with excellent interpersonal and presentation skills
- Ability to remain resilient and adapt in high-stress, fast-paced environments.
