SCHOTT HermeS® Hermetic Through Glass Vias (TGV)
SCHOTT HermeS® is a glass substrate with hermetically sealed solid “Through Glass Vias” (TGV). It enables fully gastight and therefore long-term robust enclosures for MEMS devices. The fine-pitched vias allow the reliable conduction of electrical signals and power into and out of the MEMS device. Since HermeS® can be placed directly under the silicon MEMS, it makes miniaturized, fully hermetic 3D Wafer Level Chip Size Packaging (WLCSP) possible.
