• Led in technical for all defect related issues from near-missed incidents to major excursions.• Drove development for new best-known methods (BKM) to strengthen inline detection to prevent defective products getting to customers.• Incorporated hybrid solution by combining different Metrology tools (CD, Thickness, SEM) to provide a complete solution for complicated problems• Performed various engineering tasks to ensure high matching rate between inline vs. end of line, zero-risk measurement, throughput improvement, tool-to-tool matching, contamination prevention, and wip balancing.

• Participated in mentorship by coordinating and providing training to new technicians and engineers. • Certified and signed off training items and ensured consistent training was delivered across all shift techs. • Owned responsibility of organizing and improving Standard Operating Procedure (SOP) to ensure 100% accuracy of BKM spread.• Represent as Inspection leader in New Product Introduction (NPI) meeting to ensure recipe readiness prior to device production.

• Developed defect inspections using KLA-Tencor BrightField inspection tools, ranging from old platform to the most advanced platform (D3, D4, D5+, D6, D30). • Daily monitored key metric daily quals and product trends and responded to Specification Process Control (SPC) to prevent excursions caused by false measurements. • Maintained Tool-To-Tool-Matching (TTTM) and feedback to Equipment team to troubleshoot any possible tool issues. Took ownership of the problem by following up and performing pre and post measurements until issue is fully resolved.• Worked closely with Defect Engineering team to optimize inspection recipes as part of yield improvement. Applied deep understanding of defect characteristics to establish sensitivity for highest yield in signal/noise ratio.

• Controlled the linear speed of film (web) transfer corresponding to the diameter of the roller using PID control • Eliminated all guesswork by automatically changing the speed and increased efficiency in roller applications • Self-taught programming with Arduino Microcontroller; familiarized with stepper motor, drive, and optical encoder

• Maintained confidentiality and evaluated student work fairly and objectively• Provided individual and general feedback to students • Analyzed students' performance and provided feedback to the instructo
