| Title | Development and optimization of advanced sample preparation techniques for MI-Series AMD devices |
| Summary | In the More-than-Moore era, advanced packaging and chiplet architectures have emerged as key solutions for meeting the ever-increasing demand for compute performance. However, these technologies, such as those implemented in AMD’s MI-series products, pose significant challenges for failure analysis (FA) sample preparation, particularly for optical fault isolation. The stacked chiplets, ultra-thin material layers, and large warpage in advanced packages make conventional methods like mechanical milling and polishing insufficient, as they lack the resolution and precision required. To overcome these challenges, a combination of techniques such as wet etching, dry etching, mechanical polishing, and contour milling must be employed. The objective is to selectively remove redundant structures while retaining the electrical integrity of the fully packaged product for subsequent electrical and optical fault isolation, all within a tight thermal budget. This project will focus on the development and optimisation of sample preparation workflows and processes to improve throughput, repeatability, and overall success rate in achieving high-quality surfaces for fault isolation. The refined workflow will be validated through both materials characterization (SEM, EDX, TEM) and electrical characterization (tester and curve tracer). Through this project, the student will gain hands-on experience with cutting-edge FA tools, advanced packaging challenges, and semiconductor material characterization, while also contributing to internal documentation and potential conference submissions. |
