Understanding Early Failure Behavior In 3D-Interconnects 2: Empirical Modeling of Broadband Signal Losses In TSV-Enabled Interconnects Open
We present empirical models for measured frequency-dependent insertion loss (|S21|) in a prototypical through silicon via (TSV) enabled 3D-IC from Sematech for characterization of defects formation due to thermal treatment. We measure |S 2…

Near-field control and imaging of free charge carrier variations in GaN nanowires Open
Despite their uniform crystallinity, the shape and faceting of semiconducting nanowires (NWs) can give rise to variations in structure and associated electronic properties. Here, we develop a hybrid scanning probe-based methodology to inve…
