Abstract

With the addition of LiF, nonstoichiometric barium titanate can be densified well after sintering at temperatures of less than 1000/spl deg/C, which is compatible with LTCC substrates. From the X-ray diffraction pattern, barium titanate is the main existing crystalline structure. On the observation of the microstructure, no delamination between substrate and capacitor layer is observed after cofiring. Both the capacitance and dissipation factor are stable over the -30/spl deg/C to 150/spl deg/C range.
嵌入在低温共烧陶瓷中的电容器
在LiF的加入下,非化学计量钛酸钡在低于1000/spl℃的烧结温度下可以很好地致密化,与LTCC衬底相兼容。从x射线衍射图来看,钛酸钡是主要存在的晶体结构。从微观结构上观察,共烧后衬底与电容器层之间没有发生分层现象。电容和耗散系数在-30/spl°C到150/spl°C范围内稳定。
