There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: The objective of this research is to develop methodologies for the failure analysis of circuits, as well as investigate the factors for accelerating testing for front-end-of-line time-dependent dielectric breakdown (FEOL TDDB). The separation of wearout mechanisms for circuits will be investigated, and the identification of failure modes for the failure samples will be analyzed. SRAMs and ring oscillators will be used to study the failure modes. The systematic and random errors for online monitoring of SRAMS will also be examined. Furthermore, the testing plans for acceleration testing will also be explored for ring oscillators. Error reduction through sampling will also be used to find the best testing conditions for accelerated testing. This work provides a way for engineers to better understand aging monitoring of circuits, and to design better testing to collect failure data.
