Abstract: An elastic device may comprise an amorphous metal comprising at least one refractory metal, at least two elements selected from periods, 4, 5, 6, 9, and 10, and at least one metalloid. A membrane may comprise a layer of silicon dioxide and a layer of amorphous metal. A MEMS device may comprise a layer of amorphous metal comprising at least one refractory metal, at least two elements selected from periods, 4, 5, 6, 9, and 10, and a metalloid. In one example, the amorphous material comprises Tantalum (Ta), Tungsten (W), and Silicon (Si). In another example, the metalloid is Silicon. In yet another example, the refractory metals comprise Niobium, Molybdenum, Tantalum, Tungsten, Rhenium, or combinations thereof.

Abstract: According to an example, a fluid ejection device may include a substrate, a resistor positioned on the substrate, an overcoat layer positioned over the resistor, a fluidics layer having surfaces that form a firing chamber about the resistor, in which the overcoat layer is positioned between the resistor and the firing chamber, and a thin film membrane covering the surfaces of the fluidics layer that form the firing chamber and a portion of the overcoat layer that is in the firing chamber.

Abstract: In an example, a printhead includes a die stack having a plurality of dies and a nozzle plate bonded together. A fluid passageway extends throughout the die stack to enable fluid to flow into a bottom die in the die stack, through the die stack, and out through a nozzle in the nozzle plate. The printhead includes a thin film passivation layer that coats all surfaces of the fluid passageway.
