Senior High Bandwidth Memory (HBM) Electrical Failure Analysis (EFA) Engineer

As a Global Quality (GQ) High Bandwidth Memory (HBM) Electrical Failure Analysis (EFA) Engineer on the DRAM/Emerging Memory Quality and Reliability Assurance team (DEMQRA) at Micron Technology, Inc., you will be responsible for the electrical characterization and electrical failure analysis (EFA) of all HBM products. You will need to distinguish whether it is package or device related failures. Preferably, you are equipped with knowledge of DRAM functionality, process, test program and device necessary for making solid judgment. You will also use a variety of test tools including the uMate tester, Merlin, Mongoose SM3, Prober, CAD layout tool, and a variety of technical drawings and schematics to perform detailed characterization on HBM products. You will record and categorize failures in order to determine failure mechanisms and characteristics. In this role, you will communicate with various engineering groups, assist lab users with equipment setup and interpretation of data, and maintain critical EFA knowledge database. You will also be expected to seek ways to improve the EFA process in order to reduce test time, increase throughput, and increase failure mechanism assignment accuracy and consistency.
