Abstract
In an ink-jet printhead, channels in which liquid ink is nucleated by a heating element defines five sides in cross-section. One of the sides is created by the main surface of a heater chip which includes the heating element, while the other four sides, forming a truncated parallelogram or diamond-shape, are defined in a channel plate abutting the heater chip. The four-sided channel in the channel plate is created by a combined process of plasma etching and wet etching.
