Experienced Yield Enhancement Technician / Tool Owner

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
