ABSTRACT:
Method of forming an orifice array for an ink jet printhead. Excimer laser radiation is used to ablate an orifice array in a cover plate having a removable backing, a front side layer formed from either an ablatable inactive material such as polyimide, a non-wettable material doped to absorb excimer radiation, or an ablatable inactive material such as polyimide with a very thin surface layer of a non-wettable material, and an intermediate layer formed from an adhesive material. First, a series of generally square indentations approximately 80 .mu.m on each side and which extends through the removable backing and the intermediate layer and partially through the front side layer to exposing an interior surface of the front side are formed at spaced locations along the back side surface of the cover plate. Next, a corresponding series of generally circular apertures approximately 40 .mu.m in diameter, each positioned in the general center of the corresponding indentation and extending through the front side layer are formed in the cover plate.
