摘要：
The electrical and microstrutural characteristics of NTC thick-film resistors, fired either on alumina or co-fired on "green" LTCC substrates, are compared. The NTC resistors, fired on LTCC (as compared to resistors on alumina substrates),. have higher sheet resistivities, higher beta factors, and also significantly higher noise indices. SEM and EDX analysis indicated the interaction between NTC and LTCC materials, mainly the diffusion of glass phase from LTCC substrate into NTC resistor.
