摘要
Microelectronic circuits need effective protection against electrical overvoltages and very often ZnO-based varistors are used. Direct fabrication of such elements together with other thick-film or LTCC components is highly desirable. Possibility of a lowering varistor sintering temperature to the range of 850 degrees C - 950 degrees C, typical of these technologies should be investigated. ZnO-based varistor ink was prepared and varistors were fabricated on alumina and LTCC substrates. Different electrodes metallurgy and firing profiles were used. Basic electrical properties and stability were determined and correlated with technology.
