摘要： A liquid ejector includes a substrate, a heating element, a dielectric material layer, and a chamber. The substrate includes a first surface. The heating element is located over the first surface of the substrate such that a cavity exists between the heating element and the first surface of the substrate. The dielectric material layer is located between the heating element and the cavity such that the cavity is laterally bounded by the dielectric material layer. The chamber, including a nozzle, is located over the heating element. The chamber is shaped to receive a liquid with the cavity being isolated from the liquid.

摘要： A method for forming a self-aligned hole through a substrate to form a fluid feed passage is provided by initially forming an insulating layer on a first side of a substrate having two opposing sides; and forming a feature on the insulating layer. Next, etch an opening through the insulating layer, such that the opening is physically aligned with the feature on the insulating layer; and coat the feature with a layer of protective material. Patterning the layer of protective material will expose the opening through the insulating layer. Dry etching from the first side of the substrate forms a blind feed hole in the substrate corresponding to the location of the opening in the insulating layer, the blind feed hole including a bottom. Subsequently, grind a second side of the substrate and blanket etch it to form a hole through the entire substrate.

摘要： A fluid ejector (200) includes a substrate (110), a MEMS transducing member, a compliant membrane (130), walls, and a nozzle. First portions of the substrate define an outer boundary of a cavity (115). Second portions of the substrate define a fluidic feed (116). A first portion (121) of the MEMS transducing member is anchored to the substrate (110). A second portion (122) of the MEMS transducing member extends over at least a portion of the cavity (115) and is free to move relative to the cavity (115). The compliant membrane (130) is positioned in contact with the MEMS transducing member. A first portion (131) of the compliant membrane covers the MEMS transducing member. A second portion (132) of the compliant membrane is anchored to the substrate. Partitioning walls (202) define a chamber that is fluidically connected to the fluidic feed (116). At least the second portion of the MEMS transducing member is enclosed within the chamber. The nozzle is disposed proximate to the second portion of the MEMS transducing member and distal to the fluidic feed.
