Abstract
An ink jet head substrate, an ink jet head and method of manufacturing the ink jet head substrate. The ink jet head substrate includes a supporting structure and at least one heat-generating resistor disposed on the supporting structure to generate a thermal energy to eject ink and made of metal carbon nitride. The metal carbon nitride is represented as a chemical formula of MCNwhere M is metal, X is within about 20 through 80, Y is within about 3 through 25, and Z is within about 10 through 60, when X+Y+Z=100. Further, the heat-generating resistor has a resistivity of 300˜2000 μΩ·Cm.
