A model for sheet resistivity of RuO/sub 2/ thick film resistors

Considerations of microstructure composition relationships led to the conclusion that RuO/sub 2/-based thick-film resistors can have five different types of microstructure for different ranges of the volume fraction of RuO/sub 2/(V/sub c/). A theoretical value consistent with the microstructure was developed to predict the sheet resistivity as a function of V/sub c/ and particle sizes of RuO/sub 2/ and glass for the range 0.032>
