Our passivation glasses are formulated and processed to achieve very low alkali and iron levels. They can be applied to semiconductors by a variety of techniques including doctor blading, photo-spinning, sedimentation, screen printing, glass beading, and electrophoresis.                                                               

Passivation glass powders are available in several standard particle size distributions and grain sizes based on the specific application requirements. We also offer low expansion glass composite versions for large wafer and/or thick layer requirements.
 
Lead in glass for use in electronic components is RoHS exempt, enabling these products to be used in RoHS compliant applications.
