You will execute CMP test runs, operate cleanroom processing and metrology equipment, collect and analyze data, and prepare records, charts, and graphs that help the engineering team evaluate process performance, identify yield issues, and test new products.

• Own experiment-preparation activities, including wafer preparation, thickness and defect measurements, log-sheet preparation, and recipe programming.
• Set up and operate CMP polishers, including Mirra and Reflexion systems, as well as wafer-cleaning and metrology equipment.
• Set up and operate CMP polishers, including Mirra and Reflexion systems, as well as wafer-cleaning and metrology equipment.
• Conduct polishing experiments using blanket and patterned wafers in accordance with defined experimental plans and cleanroom procedures.
• Perform process and equipment troubleshooting during experiments, including identifying potential sources of polishing variation.
• Own experimental data collection, preliminary analysis, and accurate documentation of results.
• Prepare clear records, charts, graphs, and experiment summaries for review by engineers and scientists.
• Provide practical input and recommendations on polishing-experiment feasibility and design based on hands‑on experience.
• Partner with engineers and scientists as a technical resource and collaborator during process‑development activities.
• Participate in the planning and execution of cleanroom and product‑line continuous improvement initiatives.
• Identify opportunities to improve cleanroom workflow, experimental execution, equipment utilization, and overall efficiency.
• Assist with the evaluation and process development of new cleanroom tools, including polishers, metrology systems, and cleaning equipment.
• Maintain detailed records of experimental methods and data, updating procedures and documentation as improvements are implemented.
• Promote a safe work environment and share responsibility for the safety of shift coworkers.

• Associate or bachelor’s degree in an engineering or related technical field preferred.
• Experience working on engineering projects, or equivalent relevant technical experience, required.
• Knowledge of and hands‑on experience with chemical mechanical planarization (CMP) preferred.
• Ability to operate wafer‑metrology equipment and accurately interpret measurement results.
• Ability to interpret CMP polishing end‑point traces; defectivity‑metrology experience is a plus.
• Ability to work with a high degree of independence, manage ambiguity, and exercise sound technical judgment.
• Strong planning, organization, attention to detail, accountability, teamwork, and communication skills.
• Ability to recognize and respond to internal customer needs in a collaborative and efficient manner.
