Glass Micro Bonding by SCHOTT Primoceler

Glass Micro Bonding is a revolutionary laser-based process that enables ultra-miniaturized hermetic packaging for highly sensitive electronics in demanding applications. The technology is pushing innovations forward in medical implants, aerospace, MEMS, and micro-optics.

Ultra reliable hermetic sealing

Glass Micro Bonding is an innovative process that opens new doors for the wafer-scale sealing of electronics with all-glass hermetic electronic packages. The hermetic seal is formed using an extremely precise laser to fuse glass-to-glass by melting only the cross section where the glass meets – an area of just a few microns – while leaving all other surfaces untouched.

Ultra miniature wafer-level chip scale packaging

Components sealed with Glass Micro Bonding can be as small as a few cubic millimeters. The technique has flexible implementation possibilities and can be performed on a chip-scale all the way up to wafers as large as 12 inches, making it simple and cost-effective to scale up for high-volume manufacturing.
