As a Process Engineer, you'll play a crucial role in designing and optimizing manufacturing processes for display and semiconductor manufacturing technologies. You will collect and analyze data, perform hardware characterization, and troubleshoot engineering issues. You'll also measure film properties, generate technical documentation, and engage with customers to resolve concerns. Process Engineers collaborate with vendors and suppliers, and become familiar with implementing new technologies and products. You will experiment, learn, and collaborate with some of the brightest minds in the semiconductor and display industries, partnering with our globally recognized R&D teams on state-of-the-art research and development projects. We are seeking a Metrology Engineer specializing in SEMVision defect analysis to strengthen our defect characterization and yield engineering capability. The ideal candidate will possess deep expertise in defect inspection, review, classification and characterize wafer defect; identify root-cause analysis of yield-impacting defects, and drive follow-up Failure Analysis (FA) to confirm defect mechanisms. This role will be instrumental in accelerating defect learning cycles, driving yield enhancement initiatives, and supporting high-volume manufacturing operations. • Operate SEMVision defect review SEM to review defects detected by brightfield / darkfield inspection tools, and perform high-resolution imaging of defect morphology. • Classify defects manually and via Automatic Defect Classification (ADC) ; build, tune, and maintain ADC recipes and defect classification libraries. • Perform EDX elemental analysis on SEMVision to identify defect composition and likely contamination sources. • Analyze defect Pareto, wafer maps, spatial signatures, and trends to separate systematic vs. random defects and identify key yield limiters . • Drive defect root-cause analysis by tracing defects back to the source process step, tool, or chamber using inline data, commonality analysis, and partition / short-loop experiments. • Define and request follow-up Failure Analysis (FA) — e.g., FIB cross-section, TEM, STEM/EDS, Auger, or SIMS — and interpret results to confirm defect mechanisms. • Correlate defect data with inline metrology, electrical test (WAT/CP), and yield data to quantify kill ratio and yield impact. • Collaborate with process integration and module teams (litho, etch, deposition, CMP, clean) to implement corrective actions and verify defect reduction. • Develop and optimize SEMVision review recipes (sampling, imaging conditions, review strategy) to improve review throughput and capture rate. • Prepare clear defect reports and present findings, root-cause conclusions, and recommended actions to cross-functional teams. • Support tool qualification, baseline defect monitoring, and excursion response activities. Qualifications • Bachelor’s or Master’s degree in Electrical Engineering, Materials Science, Physics, Chemical Engineering , or a related field. • 2+ years of experience in semiconductor defect review, yield, process, or FA engineering preferred; strong new graduates with relevant internship or research experience are welcome. • Basic semiconductor knowledge in process integration — understanding of front-end and back-end process flows (litho, etch, deposition, CMP, implant, clean) and how process steps interact. • Basic knowledge of yield analysis — defect density, kill ratio, defect Pareto, wafer map signatures, and yield–defect correlation. • Hands-on experience with SEM / defect review SEM (e.g., SEMVision) and defect inspection tools is a strong plus. • Familiarity with FA techniques (FIB, TEM, EDX/EDS, Auger, SIMS) and ability to interpret FA results. • Working knowledge of data analysis tools such as JMP, Excel, Klarity / yield management systems ; Python or scripting is a plus. • Strong analytical and problem-solving skills with a logical, data-driven approach to root-cause analysis. • Good communication skills with the ability to present technical findings clearly to cross-functional stakeholders. • Detail-oriented, self-motivated, and able to manage multiple defect investigations in parallel. Core Competencies Functional Knowledge • Applies working knowledge of defect review, defect classification, and FA methodologies to solve yield problems. • Understands how upstream and downstream process steps interact to generate defects. Business Expertise • Understands how defect reduction drives yield, cost, and time-to-ramp , and prioritizes work by yield impact. Leadership • Owns defect investigations end-to-end, from SEMVision review through FA to corrective-action verification. Problem Solving • Solves defect problems of moderate complexity using structure…
