Matthias Wietstruck: Through-Silicon Vias in SiGe BiCMOS and Interposer Technologies for Sub-THz Applications, Kartoniert / Broschiert

Klappentext

In the dissertation "Through-Silicon Vias in SiGe BiCMOS and Interposer Technologies for sub-THz Applications", a through-silicon via (TSV) technology module is developed targeting high frequency packaging applications in the millimeter-wave and sub-THz frequency range.
Based on a high-performance 130 nm SiGe BiCMOS technology, TSVs are embedded in a via-middle integration approach. The TSV process module consists of the TSV integration, a carrier wafer handling and a wafer backside process to realize a redistribution layer. A process flow was developed to realize TSV structures with various geometries to ensure a high TSV design flexibility. The TSV process module can be applied for SiGe BiCMOS as well as for interposer technologies.
High-performance TSV interconnections have been simulated to optimize their electrical properties. TSVs were electrically characterized and 3D transitions with low insertion loss
