Abstract: Piezoelectric actuators are provided. In some instances, the piezoelectric actuators are high-precision piezoelectric actuators. The piezoelectric beams may have a bi-chevron configuration. Also provided are methods of making the piezoelectric actuators, e.g., using Micro-Electro-Mechanical System (MEMS) fabrication techniques, and methods of using the piezoelectric actuators, e.g., as valves in fluid dispensing systems.

Abstract: An image sensor and method of making such sensor is described. The sensor includes an integral color filter array, comprising: a semiconductor substrate having an optically planar top surface; a plurality of spaced image pixels formed in the substrate; and an array of physically contiguous color filter elements embedded in the substrate whose top and bottom surfaces are coplanar and which have no overlap of color filter layers between adjacent color filter elements.

Abstract: A thermal print head which includes an array of individually addressable resistors on a substrate is provided to substantially reduce undesirable drift in the resistance values of the resistors. The thermal print head includes a thermally stable glaze having a smooth surface formed on the substrate, and an electrically resistive doped-semiconductive layer formed on the smooth glaze surface. An array of first and second electrode pairs is formed on the resistive layer such that each of the electrodes forms a gap therebetween. A protective layer is formed over the electrode pairs and over the resistive layer at the gap. An electrically conductive layer is formed on the protective layer. The thermal print head includes a structure for applying first and second potentials respectively to the first and second electrodes of each of the pairs for selectably heating each of the resistors, and applying a third potential to the conductive layer.

Abstract: A liquid ink, drop-on-demand pagewidth printhead including a semiconductor substrate, a plurality of drop-emitter nozzles fabricated on the substrate; an ink supply manifold coupled to the nozzles; pressure element for subjecting ink in the manifold to a pressure above ambient pressure; a drop selection device for selectively addressing predetermined nozzles, and drop separation device to transfer ink selected drops from selected nozzles to a print region. A surface tension reducing agent for each nozzle is provided from a supply separate from the ink and integrated into the printhead. An increase in ink drop protrusion from the nozzle surface differentiates selected drops from non-selected drops.

Abstract: An image sensor which includes an integral color filter array and a method of making such sensor is disclosed. The sensor includes a semiconductor substrate having an overlying support layer with an optically planar surface, a plurality of spaced image pixels formed in the substrate; and an array of contiguous color filter elements overlying the planar surface whose top surfaces are coplanar and which have no overlap of color filter material between adjacent color filter elements.

Abstract: A method of making a fully self-aligned, planar, two phase charge coupled device comprises the steps of first forming upon a semiconductive substrate a uniform dielectric; then implanting ions of a second conductivity type into the substrate, then patterning closely spaced first conductive strips of a first conductive layer on the dielectric, then further implanting ions of the first or second conductivity type in the regions between said first conductive strips, then depositing uniformly a second conductive layer electrically isolated from the first conductive strips by an insulative region, then entirely removing by uniform planarization those portions of the second conductive layer disposed over regions of the first conductive strips so as to form coplanar, alternating first and thick electrically isolated conductive strips, then depositing a second insulative layer, then electrically connecting selected adjacent first and second conductive strips together to form first and second composite gate electrodes
