    Abstract: Processes for making a membrane having a curved feature are disclosed. Recesses each in the shape of a reversed, truncated pyramid are formed in a planar substrate surface by KOH etching through a mask. An oxide layer is formed over the substrate surface. The oxide layer can be stripped leaving rounded corners between different facets of the recesses in the substrate surface, and the substrate surface can be used as a profile-transferring substrate surface for making a membrane having concave curved features. Alternatively, a handle layer is attached to the oxide layer and the substrate is removed until the backside of the oxide layer becomes exposed. The exposed backside of the oxide layer includes curved portions protruding away from the handle layer, and can provide a profile-transferring substrate surface for making a membrane having convex curved features.

    Abstract: Fluid ejection nozzles having a tapered section leading to a straight walled bore are described. Both the tapered section of the nozzle and the straight walled bore are formed from a single side of semiconductor layer so that the tapered section and the bore are aligned with one another, even when an array of nozzles are formed across a die and multiple dies are formed on a semiconductor substrate.

    Abstract: A method of forming a nozzle plate of a fluid ejection device includes etching a bore in the first side of the multi-layer substrate, depositing a liner in the bore, removing a layer from a second side of the multi-layer substrate, wherein the removing exposes a closed end of the liner, applying a non-wetting coating to the closed end of the liner and an area surrounding the closed end of the liner, and removing the closed end of the liner, wherein removing the closed end of the liner opens a nozzle.

    Abstract: Processes for making a profile-transferring substrate surface and membranes having curved features are disclosed. A profile-transferring substrate surface having a curved feature is created by isotropic plasma etching through a shadow mask. The shadow mask has a through hole which has a lower portion adjacent to the bottom surface of the shadow mask and an upper portion that is above and narrower than the lower portion. The isotropic plasma etching through the shadow mask can create a curved dent in a planar substrate in a central portion of an area enclosed by the bottom opening. After the shadow mask is removed. A uniform layer of material deposited over the exposed surface of the substrate will include a curved feature at the location of the curved dent in the substrate surface.
