APPLICATIONS REPORT ON REPRODUCIBLE THERMISTOR REFINEMENT PROGRAM
Abstract
Gold-doped noncrystalline silicon exhibits temperature-resistivity behavior suitable for making highly reproducible, predictable and sensitive thermistors. Two types of thermistors were developed with reproducibilities of =2% and operable ranges including -85 to 200 C. Manufacturing methods were developed and demonstrated on an unbalanced pilot line. A literature survey indicated that specially doped silicon or germanium offer the best possibilities of being used as single-crystal semiconductor thermistors. Silicon was chosen for development on the basis of energy gap, purity, resistivity, and availability. Many elements were screened as possible silicon thermistor dopants. These include gold, copper, silver, nickel, iron, zinc, platinum, manganese, and thallium. Only gold in both P and N-type silicon gave products suitable for use in the -85 to 200 C range.
