Product Yield Enhancement (PYE) Engineer

Job Title

Product Yield Enhancement (PYE) Engineer

Role Summary

The Product Yield Enhancement (PYE) Engineer performs electrical failure analysis and fault isolation to identify and eliminate yield-limiting defects across the manufacturing lifecycle for memory products. The role works within the PYE team and collaborates with Product, Process, Assembly, and Global Quality groups to drive reliability, ramp production, and reduce time to market.

Experience Level

Mid-level — typically requires 2+ years of relevant experience in semiconductor failure analysis, yield enhancement, or a closely related field.

Responsibilities

Primary duties include electrical and physical failure analysis, data-driven root-cause identification, and cross-functional communication of findings and corrective actions.

• Perform electrical failure analysis and fault isolation using emission microscopy, laser techniques, EOTPR, and physical failure analysis (PFA) / de-processing methods.
• Characterize and model test, qualification, and RMA fail signatures using layout, schematic, and data-analysis tools.
• Apply knowledge of CMOS fabrication and package assembly flows to identify process- and assembly-related defects and downstream effects.
• Evaluate reliability concerns and delayed-breakdown failure mechanisms across test insertions.
• Extract and analyze fab, probe, and backend test data to support failure analysis conclusions.
• Generate organized, timely failure analysis reports with clear causes, effects, and recommended actions.
• Present and coordinate findings with Management, Product, Process, Assembly, and Global Quality teams to implement corrective actions.

Requirements

Must-have:

• 2+ years of experience in semiconductor failure analysis, yield enhancement, or closely related field.
• Hands-on experience with fault-isolation techniques, including emission microscopy, laser-based methods (e.g., OBIRCH/TIVA), and EOTPR.
• Experience with physical failure analysis tools and de-processing techniques (FIB, cross-sectioning, delayering).
• Working knowledge of CMOS fabrication processes and package assembly flows.
• Proficiency reading and interpreting semiconductor layout and schematic designs.
• Ability to perform data extraction and analysis from fab, probe, and backend test systems.
• Strong written and verbal communication skills; able to produce clear failure analysis reports.

Nice-to-have / Preferred:

• 4+ years of electrical failure analysis experience in a high-volume semiconductor manufacturing environment.
• Experience with memory products (DRAM, NAND, HBM).
• Advanced proficiency with EFA techniques such as photon emission, laser voltage probing (LVP), and thermal laser stimulation.
• Familiarity with reliability failure modes (electromigration, TDDB, HCI) and delayed breakdown mechanisms.
• Experience modeling or characterizing complex fail signatures across test insertions.
• Experience with data-analysis tools or scripting languages (Python, JMP, MATLAB).
• Demonstrated ability to collaborate cross-functionally and present technical findings to senior leadership.

Education Requirements

Required: Bachelor's degree in Electrical Engineering, Materials Science, Physics, or a related technical discipline. Preferred: Master's degree or Ph.D. in Electrical Engineering, Materials Science, Physics, or a related field.
