Abstract: Micro-fluid ejection devices, such as inkjet printheads, such as those that use a laser to eject fluid. One such micro-fluid ejection device includes a passageway plate defining a fluid chamber filled with fluid and a fluid channel to supply the fluid chamber with fluid, a top plate provided on the passageway plate, a fluid ejection hole formed through the top plate at a position corresponding to the fluid chamber, a condenser lens provided on a bottom surface of the passageway plate at a position corresponding to the fluid chamber, and laser beam irradiator capable of irradiating a laser beam through the condenser lens and into fluid contained in the fluid chamber, wherein the fluid is nucleated by the laser beam such that a vapor bubble forms and displaces a portion of the fluid, thereby ejecting a fluid droplet through the fluid ejection hole. Method of using such devices are also disclosed.

Abstract: Methods for improving the thermal conductivity of a substrate for a micro-fluid ejection head and micro-fluid ejection heads are provided. One such head includes a substrate having a thermal conductivity ranging from about 1.4 W/m-° C. to about 148 W/m-° C., a fluid ejection actuator, and a thermal bus thermally adjacent to the substrate and configured to dissipate heat associated with the operation of the actuator. Exemplary modified substrates have improved thermal conductivity characteristics as compared to a corresponding substrate not modified to include the thermal bus.
