Areas of application for customized glass wafer from PLANOPTIK
The advantages of glass as a wafer material are particularly evident in the field of microsystem technology. Industries such as consumer electronics, automotive and sensor technology are increasingly relying on the material glass for example for wafer-level packaging (WLP) or fan-out wafer level packaging (FOWLP) applications. Typical applications are:
As a leading wafer manufacturer, PLANOPTIK AG produces glass wafer for these growing markets. The wafers which are used for instance in driver assistance systems, motor controls or medical technology meet high standards in terms of thickness tolerance or surface quality. The unique glass wafer fabrication developed by PLANOPTIK as well as many years of experience in the field of glass processing enable the production of high quality wafers that exactly meet customer requirements.
