What You’ll Be Doing
- Lead reliability activities throughout the product development lifecycle to ensure successful qualification of new semiconductor products and technologies.
- Develop qualification strategies, test plans, and reliability requirements for new products, process changes, and manufacturing improvements.
- Execute and analyse reliability testing including accelerated tests (high temperature and high electrical stress) and environmental tests in climate chambers
- Perform failure rate predictions and lifetime assessments using wear-out modelling, Weibull analysis, Arrhenius modelling, and other reliability methodologies.
- Monitor, identify, and investigate early-life failures, random failures, and wear-out mechanisms.
- Drive root cause investigations and failure analysis activities to identify reliability risks and implement corrective actions.
- Coordinate reliability requirements and qualification activities with Design, Product, Test Development, Process Engineering, and Manufacturing teams.
- Own qualification reporting and communicate reliability results to project teams, management, customers, and external stakeholders.
- Maintain and continuously develop reliability test methods, data analysis techniques, and laboratory capabilities.
- Support volume manufacturing by monitoring ongoing reliability performance and driving continuous improvement initiatives.
- Apply statistical analysis and data-driven decision making to evaluate product reliability and process capability.
- Act as a technical authority for reliability qualification decisions, approving or rejecting qualification results against defined specifications.
