Forming features in printhead components

摘要

In a method of forming a feature in a printhead component, femtosecond laser beam pulses (202) are scanned over a target zone (210) of a printhead substrate (208) to remove a layer of the printhead substrate. The scanning is repeated until a depth of printhead substrate has been removed from the target zone which corresponds to a desired feature depth. The removed portion of the printhead substrate forms at least part of the feature in the printhead component.
