ABSTRACT:
A method for manufacturing a thin film negative temperature coefficient thermistor is disclosed. The method includes selecting a negative temperature coefficient of resistance versus temperature curve, selecting a mixture of metal film materials to provide the negative temperature coefficient of resistance curve while maintaining a desired physical size, and depositing the mixture of metal film materials on a substrate.
