Vertical interconnections using through encapsulant via (TEV) and through silicon via (TSV) for high-frequency system-in-package integration
Abstract
In this paper we investigate two vertical interconnect options for high-frequency system-in-package (SiP) integration: through encapsulant via (TEV) applied to the embedded wafer level ball grid array (eWLB) technology and through silicon via (TSV). We compare both solutions in terms of size and electrical performance. We use analytic expressions and electromagnetic simulations for our analysis and present measurement results of selected structures for verification. The results show that the choice of TEV and TSV depends on application and cost window.
