Abstract
A new sintering aid system of boron lithium glass for LTCC layer is introduced. Due to the existence of liquid phase, the sintering temperature of barium strontium titanate decreases from 1350 °C to 950°C. The effects of B-Li glass in LTCC devices were studied. The samples which sintering temperature at 950°C shows optimize the dielectric performance, including low dielectric constant is 368 and low dielectric loss is 0.007. Dielectric tunability of simple LTCC multilayer ceramic capacitor devices are manufactured by tape casting process. The measured capacitance increases with the increase of layers, and the tunability is stable at 12% (300 volts).
