Sr. Yield Engineer, Metrology, Terafab

What To Expect
We are building Terafab, a vertically integrated semiconductor factory at an unprecedented scale. The facility houses logic, memory, packaging, test, and lithography mask production under one roof, optimized for rapid iteration and maximum compute density per square foot.

Yield is the ultimate scorecard of a fab. As a Yield & Metrology Engineer at Terafab, you will build the data infrastructure, defect learning systems, and metrology strategy that drives Terafab chip manufacturing to world-class yield levels. You will connect electrical test data, inline defect inspection, physical failure analysis, and process signals to identify and eliminate the systematic yield limiters that determine Terafab's viability.

What You'll Do

Build Terafab's yield learning infrastructure from the ground up: defect inspection sampling plans, inline metrology flows, and electrical test correlation frameworks

Lead systematic yield analysis using defect pareto, binning analysis, parametric correlation, and spatial signature decomposition

Own the inline metrology strategy across all critical layers: CD, overlay, film thickness, defect density, and electrical continuity

Drive defect reduction programs across all yield-limiting defect types such as particles, pattern defects, etch residues, shorts, and opens

Partner with process, equipment, and integration engineers to close the loop between yield data and corrective actions

Develop automated data pipelines, yield dashboards, and early warning systems using Python, SQL, and internal data tooling

Lead physical failure analysis (PFA) including FIB/SEM cross-sections, EBAC, and TEM sample preparation

Build die-level yield models and simulation capabilities to project yield at scale and prioritize defect investment

What You'll Bring

Degree in Electrical Engineering, Physics, Materials Science, or equivalent experience

5 years of yield engineering or metrology engineering experience in a leading-edge semiconductor fab

Strong proficiency in yield analysis: defect pareto, spatial analysis, electrical bin correlation, and parametric yield modeling

Experience with defect inspection and review tools (KLA, Camtek) and defect classification systems

Experience building yield learning systems from scratch in a greenfield fab environment

Experience in ML/AI-based defect classification or yield prediction modeling

Solid programming skills in Python or R for data analysis, visualization, and process control automation

Familiarity with wafer sort, electrical test structures, and EDS analysis for yield learning

Familiarity with FIB/SEM sample preparation and advanced PFA techniques
