Popis: The use of borosilicate glass for anodic wafer bonding to silicon is well established in industry. In this paper we present a matured approach, where a microstructured borosilicate glass thin-film instead of a bulk glass wafer is used as anodic bond layer. A glass layer with a thickness of 3 – 5 µm is sufficient for a stable bond at very moderate bond parameters with bond voltages in the range of 30 – 60 V at standard bond temperatures of around 300 °C and below. This enables the use of anodic bonding also for sensitive devices.
