Abstract
A spreading-resistance silicon thermistor having high-precision values of resistance and temperature coefficient of resistance (TCR) is produced by a high-volume, low-cost, photolithographic technique, wherein multiple thin-film contacts are tested and selectively trimmed to permit computerized control of precision resistance values in a production-line operation.
