Our vision is to transform how the world uses information to enrich life for all . Micron Technology is a world leader in innovating memory and storage solutions that accelerate the transformation of information into intelligence, inspiring the world to learn, communicate and advance faster than ever. As a Product Yield Enhancement (PYE) Electrical Failure Analysis (EFA) Engineer, you will work with a team dedicated to improving yields of next-generation memory products across all stages of the manufacturing lifecycle. Through failure analysis of test, internal qualification, and RMA failures, you will identify and help eliminate yield-limiting defects — driving enhanced product reliability, rapid production ramp, and early time to market. Your day-to-day work will center on fault isolation using a combination of electrical and physical characterization techniques paired with data analysis to pinpoint physical defects introduced during process fabrication or package assembly. You will also be responsible for presenting and coordinating failure analysis findings with Management, Product, Process, Assembly, and Global Quality teams to ensure corrective actions are implemented and yields continue to improve. Responsibilities Perform Electrical Failure Analysis and Fault Isolation using emission microscopy, laser techniques, EOTPR, and PFA/de-processing methods Characterize and model backend test, internal qualification, and RMA fail signatures using layout, schematic, and data analysis tools Apply in-depth knowledge of CMOS fabrication processes and package assembly flows to identify process- and assembly-related defects, root causes, and downstream effects Evaluate reliability concerns and delayed breakdown failure mechanisms across test insertions Perform

Job description
Location: Hybrid - SF Employment: Full-time Develop and qualify Volantis’s testing procedures for custom lasers and scale for mass production. You will own development and implementation of testing and reliability procedures for our first- and second-generation custom laser designs, and their integration with the wafer-scale interposer. Responsibilities Partnering with the laser design team to define test plans, specifications and pass/fail criteria for new individually addressable VCSEL array designs. Characterizing prototype devices (LIV, spectral, far-field/beam profile, polarization, thermal and high-speed modulation) and delivering timely analysis that feeds back into design iterations. Managing test data, including databases, wafer maps, yield analysis and SPC, to track device performance and process variation in conjunction with the designers. Designing, building and maintaining w
