Process Engineer Metrology & Yield Enhancement

Quantum Computing Inc. (QCi) is an innovative company focused on accessible quantum machines. The Process Engineer for Metrology & Yield Enhancement will oversee the development of wafer line processes, collaborate with teams to enhance product yields, and ensure quality through metrology and calibration programs.

Responsibilities:

• Lead the development and optimization of photolithography and/or wet processes for compound semiconductor applications
• Drive process integration and improvement initiatives to enhance device performance and yield
• Work closely with the process team in the cleanroom to optimize associated metrology measurements in the fabrication flow of TFLN chips
• Facilitate the transition of research level chip scale production, to low, to middle volume manufacture at wafer scale
• Utilize advanced metrology tools such as CD SEM, AFM, ellipsometry, profilometry, XPS, XRD, and optical interferometry for process characterization and defect analysis
• Work closely with integration, production, and device engineering teams to integrate photo and/or wet processes into the overall semiconductor fabrication flow
• Troubleshoot process deviations, particle contamination, and unit performance issues, implementing corrective actions and continuous improvement strategies
• Establish and maintain SPC for process monitoring and optimization
• Evaluate and qualify new photo and/or wet chemistries, masks, hardware configurations, and process automation tools
• Develop and document process recipes, work instructions, and standard operating procedures (SOPs)
• Mentor junior engineers and provide /or leadership in semiconductor photo, wet, mask, and associated metrology

Requirements:

• 5+ years' experience in Process Development and Continuous Improvement through predictive/preventive metrology measurement & yield enhancement analysis programs
• Optical modeling and analysis for coherent micro-optical and photonic systems to understand how systems and in new and novel ways to create, deliver and measure light in our next generation quantum computer systems
• Apply advanced statistical and analytical methods to identify, quantify, and control risk in complex manufacturing environments
• Translate PFMEA outputs into actionable process controls, ensuring proactive prevention of variation rather than reactive correction
• Define and implement the inspection methods, calibration systems, and SOPs
• Manage calibration programs and maintain compliance with ISO and customer quality standards
• Deploy advanced sampling strategies, SPC controls, Cp/Cpk, GR&R, and integrate Minitab/JMP analytics into daily operations
• Experience with process characterization and metrology techniques such as/or equivalent SEM, AFM, KLA Optical profiler, Stylus profiler, microscope, spectral analysis, and ellipsometry
• 10+ years' experience in Metrology & Yield Enhancement Process development, process integration
• Experience and understanding of microfabrication for photonics devices, process integration, photonic materials properties and modification, and the incorporation of MEMS and electronic devices. Specific knowledge of lithography, etching, deposition, and associated processing is highly valued
• Apply large-scale data analytics to Track-and-Trace datasets, enabling predictive insights and real-time defect containment
• Experience with heterogeneous bonding between wafers and chips is valued
• Experience working with 5S, and 6 Sigma
