Abstract
Micro-fluid ejection devices, methods for making micro-fluid ejection heads, and micro-fluid ejection heads, including a micro-fluid ejection head. One such micro-fluid ejection head has relatively high resistance thin film heaters adjacent to a substrate. The thin film material comprises silicon, metal, and carbon (SiMC wherein M is a metal). Each thin film heater has a sheet resistance ranging from about 100 to about 600 ohms per square and a thickness ranging from about 100 to about 800 Angstroms.
