Abstract
Ternary metal nitride layers suitable for thin-film resistors are fabricated by forming constituent layers of complementary components (e.g., binary nitrides of the different metals, or a binary nitride of one metal and a metallic form of the other metal), then annealing the constituent layers to interdiffuse the materials, thus forming the ternary metal nitride. The constituent layers (e.g., 2-5 nm thick) may be sputtered from binary metal nitride targets, from metal targets in a nitrogen-containing ambient, or from metal targets in an inert ambient. Optionally, a nitrogen-containing ambient may also be used for the annealing. The annealing may be 10 seconds to 10 minutes at 500-1000° C. and may also process another component on the same substrate (e.g., activate a diode).
