Ink jet print head producing simulation and methods

Summary form only given. The process for manufacturing a thin film resistor substrate is useful in fabricating an ink jet print head, wherein discontinuous strips of conductive material are initially patterned on the surface of a resistive layer. Thermal ink jet print heads play a dominant role in drop-on-demand print head technology. Improvements of efficiency and lifetime are an ongoing challenge for research and development in this field. Commonly used micro heaters are based on refractory metal alloys. Therefore, a complex stack of various materials is necessary to protect the heater against oxidation and mechanical strains that limit the performance of such micro heaters. In this paper, production simulations play a dominant role in making the product cost effective. We research methods of production simulation for thin film devices for an ink jet print head.
