Abstract:
1. A micro-fluid ejection head comprising relatively high resistance thin film heaters adjacent to a substrate, the thin film heaters being comprised of a thin film material comprising a silicon, metal, and carbon (SiMC, wherein M is a metal), the SiMC thin material comprising Si x M y C z , wherein M is one of tantalum and chromium, and x, y, and z are integers each ranging from about 10 to about 60 and x+y+z=100, and wherein thin film heaters have a sheet resistance ranging from about 100 to about 600 ohms per square and the SiMC thin film material of the heater has a thickness ranging from about 100 to about 800 Angstroms.
