Experienced Yield Enhancement Technician / Tool Owner

Job description

The Yield Enhancement Technician / Tool Owner is responsible for improving manufacturing yield, optimizing process tool performance, and ensuring equipment reliability within a semiconductor fabrication environment. This role combines hands-on technical support with ownership of specific process tools, driving continuous improvement through data analysis, troubleshooting, and collaboration with engineering teams. Primary Responsibilities: Monitor wafer yield metrics and identify trends, excursions, and systematic defects. Perform root cause analysis on yield loss using defect inspection, SPC charts, and process data. Implement corrective and preventive actions to improve yield and reduce variation. Analyze inline and end-of-line data to detect early warning signals for yield degradation. Work closely with process engineers, integration engineers, maintenance technicians, and operations teams. Serve as the primary technical owner for assigned inspection tools (e.g., KLA2367, SP1/2, Puma, Altair). Ensure tool uptime, availability, and performance meet fab targets. Track and drive key tool metrics such as OEE (Overall Equipment Effectiveness) and uptime. Qualify tools after maintenance, upgrades, or process changes to ensure production readiness. Provide training and technical guidance to operators and junior technicians. Required Qualifications Associate’s or Bachelor’s degree in Electrical Engineering, Materials Science, Chemical Engineering, or related field. 3+ years of experience in semiconductor manufacturing, equipment engineering, or yield improvement. Strong problem-solving and analytical skills. Familiarity with SPC, FDC, and yield management systems. Knowledge of specific semiconductor process areas (e.g., lithography, etch, deposition). Familiarity with semiconductor defect inspection and metrology tools. Analytical thinking and root cause problem-solving. Attention to detail and data-driven decision making. Strong communication and teamwork skills. Semiconductor fabrication facility (cleanroom environment). Requires use of cleanroom attire (bunny suit). Must be able to lift and carry objects up to 25 pounds. May include shift work, on-call support, or extended hours during critical issues More information about NXP in the United States...
