1. An NTC thin film thermistor comprising:
a plurality of first thin film electrodes;
a plurality of second thin film electrodes; and
at least two layers of NTC thin film, wherein a respective layer of the at least two layers of NTC thin film is disposed between a respective one of the plurality of first thin film electrodes and a respective one of the plurality of the second thin film electrodes,
wherein the plurality of first thin film electrodes overhangs on a first side of the NTC thin film thermistor with respect to the at least two layers of NTC thin film and the plurality of second thin film electrodes are shortened on the first side with respect to the at least two layers of NTC thin film, and
wherein the plurality of second thin film electrodes on a second side of the NTC thin film thermistor opposite to the first side overhangs with respect to the at least two layers of NTC thin film and the plurality of first thin film electrodes on the second side are shortened with respect to the at least two layers of NTC thin film.
