    Abstract: Hot-melt sealing glass compositions that include one or more glass frits dispersed in a polymeric binder system. The polymeric binder system is a solid at room temperature, but melts at a temperature of from about 35° C. to about 90° C., thereby forming a flowable liquid dispersion that can be applied to a substrate (e.g., a cap wafer and/or a device wafer of a MEMS device) by screen printing. Hot-melt sealing glass compositions according to the invention rapidly re-solidify and adhere to the substrate after being deposited by screen printing. Thus, they do not tend to spread out as much as conventional solvent-based glass frit bonding pastes after screen printing. And, because hot-melt sealing glass compositions according to the invention are not solvent-based systems, they do not need to be force dried after deposition.

    Abstract: The present invention provides an electronic device having a lead-free and cadmium-free glass composition applied thereto and fired to form an acid resistant overglaze, and a method of overglazing an electronic device using the lead-free and cadmium-free glass composition. The lead-free and cadmium-free glass composition fuses at low firing temperatures and is particularly suitable for use in thick film pastes. The glass composition forms predominantly bismuth titanate and/or zinc titanate crystals upon firing. Preferably, glass compositions include by weight from about 11% to about 52% SiO2, from 3.4% to about 40% TiO2, up to about 75% Bi2O3, up to about 40% by weight ZnO, where the sum of Bi2O3 and ZnO comprises from about 15% to about 85% of the glass composition by weight.
