Abstract
An assembly for selectively etching an inkjet printhead includes a substrate and printhead layers formed on the substrate. A bonding region can provide a location on the printhead layers for an electrical bond. An ink channeling region can be defined at least in part by the printhead layers. A mask layer can partially cover the printhead layers and include a first opening positioned over the bonding region and a second opening positioned over the ink channeling region. The assembly can also include a via at the first opening and a trench at the second opening having greater depth than the via.
