    Abstract: A method of forming a micro-structure involves forming a multi-layered structure including i) an oxidizable material layer on a substrate and ii) another oxidizable material layer on the oxidizable material layer. The oxidizable material layer is formed of an oxidizable material having an expansion coefficient, during oxidation, that is more than 1. The method further involves forming a template, including a plurality of pores, from the other oxidizable material layer, and growing a nano-pillar inside each pore. The nano-pillar has a predefined length that terminates at an end. A portion of the template is selectively removed to form a substantially even plane that is oriented in a position opposed to the substrate. A material is deposited on at least a portion of the plane to form a film layer thereon, and the remaining portion of the template is selectively removed to expose the nano-pillars.

    Abstract: A method of forming capped nano-pillars on a substrate includes forming a template on the substrate, the template defining nano-pores having a first width. The nano-pores are partially filled to define nano-pillar stem portions of a first thickness corresponding to the first width. The nano-pores are re-shaped to define re-shaped nano-pore sections having a second width different than the first width. The re-shaped nano-pore sections are at least partially filled to define nano-pillar cap portions of a second thickness corresponding to the second width. The method further includes removing the template.

    Abstract: In one example In accordance with the present disclosure, a fluid ejection device is described. The fluid ejection device Includes a number of nozzles to eject fluid. Each nozzle Includes multiple firing chambers to hold fluid. The multiple firing chambers are separated: by a chamber partition. Each nozzle also includes a shared nozzle orifice in a substrate through which to dispense fluid. Each nozzle also Includes multiple ejectors, at least one ejector disposed in each firing chamber, in a common channel of the nozzle, fluid from the multiple firing chambers Is mixed, A height of the common channel is defined by the substrate and the chamber partition and is less than a width of the shared nozzle orifice.
