Passivation Glass

SCHOTT passivation glass powders are high-purity materials used for chemical and mechanical strengthening of semiconductor and varistor surfaces. The applied glass layer provides dependable protection for passivating p-n-junctions and acts as hermetic housing for discrete devices. The collection features comprehensive options of glass compositions with only the finest raw materials chosen to enable high material purity and low alkaline content. Lead-free glass frits are available for all common passivation applications, including sinter glass diodes and rectifiers, wafer passivation (including thyristors and diodes), and the glazing of high-voltage varistors. The products deliver a diverse range of properties including high insulation resistance and precise combinations of elements to match specific components.
