For those looking to make their mark on purposeful and enduring innovation, above and beyond fleeting trends, Marvell is a place to thrive, learn, and lead. Your Team, Your Impact We are seeking an experienced Package Reliability Engineer with expertise in 2.5D/3D advanced packaging. The ideal candidate will have a strong background in physics of failure, materials science, and experience working closely with OSATs to drive package reliability improvements. This role requires collaboration with external assembly and test partners, internal design, process, and failure analysis teams, and suppliers to ensure the reliability and manufacturability of cutting-edge semiconductor packages. What You Can Expect Reliability Analysis & Risk Assessment: Conduct physics of failure (PoF)-based reliability modeling for 2.5D/3D advanced packaging. Assess package reliability risks from thermal, mechanical, and electrical stressors. Define and execute stress test plans (e.g., thermal cycling, humidity, electromigration) to validate package robustness. OSAT Management & Collaboration: Work closely with OSAT partners to drive package reliability improvements, process optimizations, and yield enhancements. Define reliability requirements, review test methodologies, and ensure OSAT compliance with JEDEC and industry standards. Monitor and evaluate OSAT performance in executing reliability qualifications and failure analysis. Support supplier audits and technical reviews to assess manufacturing capabilities and reliability processes. Material Characterization & Selection: Evaluate and select materials (substrates, dielectrics, adhesives, underfills) for optimal reliability. Analyze CTE mismatches, warpage, delamination, and interfacial adhesion issues. Work with material suppliers and OSATs to qualify new materials for advanced packaging applications. Failure Analysis & Root Cause Identification: Lead failure mode analysis (FMEA), model-based problem solving (MBPS) and determine root causes of package failures using techniques such as FIB, X-ray, SEM, and TEM. Identify and mitigate interfacial failures, cracking, voiding, electromigration, and stress-induced damage. Drive OSATs and internal teams to implement corrective and preventive actions (CAPA). Process & Design Collaboration: Work cross-functionally with internal design, process, and manufacturing teams to define assembly test vehicles and optimize package architectures. Develop and refine design guidelines, process improvements, and reliability best practices. Stay up to date with industry standards (JEDEC, IPC, IEEE, etc.) and implement best practices in package reliability.
