HermeS® glass wafer substrates with hermetically sealed, solid through-glass vias (TGV) enable ultra-miniaturized, fully hermetic sensors and MEMS devices in Wafer Level Chip Size (WLCSP). The extremely fine-pitched vias enable reliable conduction of electrical signals and power into and out of the MEMS device.

Ultra-reliable, chip-size MEMS packaging

From macro to micro, HermeS® TGV wafers provide electronic packaging for MEMS devices, including miniaturized applications in large-scale industrial and automotive sensors and medical equipment, in which medical electronics can be packaged to withstand body fluids and sterilization cycles over long periods of time.

Advantages over TSV and ceramic packaging

As glass has higher resistance properties, HermeS® TGV wafers can significantly extend the long-term efficiency of MEMS devices. Excellent RF performance and optical transparency are further advantages, while the superior miniaturization capabilities allow a 80% smaller foot print over ceramic packaging, as the TGVs can be directly attached to the silicon MEMS.
