Patent ID: 10054497

Abstract:
A metal nitride material for a thermistor consists of a metal nitride represented by the general formula: MxAly(N1-wOw)z (where “M” represents at least one of Fe, Co, Mn, Cu, and Ni, 0.70≤y/(x+y)≤0.98, 0.45≤z≤0.55, 0<w≤0.35, and x+y+z=1), wherein the crystal structure thereof is a hexagonal wurtzite-type single phase. A method for producing the metal nitride material for a thermistor includes a deposition step of performing film deposition by reactive sputtering in a nitrogen and oxygen-containing atmosphere using an M-Al alloy sputtering target (where “M” represents at least one of Fe, Co, Mn, Cu, and Ni).
