Abstract

A piezoelectric film stack is created by forming a lower electrode stack on a structured substrate. A pyrochlore lead zirconium titanate (PZT) buffer substrate layer is then formed on the lower electrode stack. A rapid thermal anneal of the PZT buffer substrate layer is then performed. Epitaxial perovskite (100) PZT film on the PZT buffer substrate layer is grown. An upper electrode stack is formed on the perovskite (100) PZT film.

Abstract

A method for ejecting fluid from a fluid ejector includes actuating a piezoelectric actuator to cause deformation of a membrane defining a wall at a first end of an elongated channel of the fluid ejector, the deformation of the membrane causing ejection of a droplet of fluid from a nozzle disposed at a second end of the channel. The elongated channel fluidically connects a first channel to the nozzle, the first channel disposed at the first end of the elongated channel, and wherein an impedance of the first channel is at least ten times greater than an impedance of the elongated channel. Deformation of the membrane induces fluid flow along the elongated channel, and wherein at least 60% of the fluid flow induced by the deformation of the membrane is in a direction extending from the first end of the elongated channel to the second end of the elongated channel.

Abstract

Embodiments reduce capacitive cross-talk between micromachined ultrasonic transducer (MUT) arrays through grounding of the substrate over which the arrays are fabricated. In embodiments, a metal-semiconductor contact is formed to a semiconductor device layer of a substrate and coupled to a ground plane common to a first electrode of the transducer elements to suppress capacitive coupling of signal lines connected to a second electrode of the transducer elements.

Abstract

Piezoelectric micromachined ultrasonic transducer (pMUT) arrays and techniques for frequency shaping in pMUT arrays are described, for example to achieve both high frequency and low frequency operation in a same device. The ability to operate at both high and low frequencies may be tuned during use of the device to adaptively adjust for optimal resolution at a particular penetration depth of interest. Various sizes of piezoelectric membranes are fabricated for tuning resonance frequency across the membranes. Signal processing of the drive and/or response signals generated and/or received from each of the two or more electrode rails may achieve a variety of operative modes, such as a near field mode, a far field mode, or ultra wide bandwidth mode.

Abstract

Piezoelectric micromachined ultrasonic transducer (pMUT) arrays and systems comprising pMUT arrays are described. Coupling strength within a population of transducer elements provides degenerate mode shapes that split for wide bandwidth total response while less coupling strength between adjacent element populations provides adequately low crosstalk between the element populations. In an embodiment, differing membrane sizes within a population of transducer elements provides differing frequency response for wide bandwidth total response while layout of the differing membrane sizes between adjacent element populations provides adequately low crosstalk between the element populations. In an embodiment, elliptical piezoelectric membranes provide multiple resonant modes for wide bandwidth total response and high efficiency.

Abstract

An apparatus includes an inkjet assembly having inkjet nozzles through each of which ink flows at a nominal flow rate as it is ejected from the nozzle onto a substrate. Ink is held under a nominal negative pressure associated with a characteristic of a meniscus of the ink in the nozzle when ejection of ink from the nozzle is not occurring. The apparatus includes recirculation flow paths, each flow path having a nozzle end at which it opens into one of the nozzles and another location spaced from the nozzle end that is to be subjected to a recirculation pressure lower than the nominal negative pressure so that ink is recirculated from the nozzle through the flow path at a recirculation flow rate. Each recirculation flow path has a fluidic resistance between the nozzle end and the other location such that a recirculation pressure at the nozzle end of the flow path that results from the recirculation pressure applied at the other location of the flow path is small enough so that any reduction in flow rate below the nominal flow rate when ink is being ejected is less than a threshold, or a change in the nominal negative pressure when ink is not being ejected is less than a threshold, or both.

For example, the pressure source can be a stream of fluid such as air. Pressure can be applied to a side of the tape opposite the surface in a region smaller than the surface to cause the tape to adhere to the substrate opposite the region. The region can be moved relative to the substrate in an outward radial direction while applying the pressure. The region can be moved such that no unadhered region of tape is enclosed by any adhered region of tape.

Abstract

Among other things, for jetting fluid droplets on a substrate during relative motion of an apparatus and the substrate along a process direction, a first and second jetting assemblies at least partially overlap in a direction perpendicular to the process direction so that some jets in the first jetting assembly align with some jets in the second jetting assembly along the process direction to form one or more pairs of aligned jets. A mechanism enables, in at least one pair of the aligned jets, one jet to jet a first fluid drop that has a size smaller than a size of a fluid drop the jet would otherwise be required to jet to form a desired pixel and the other jet to jet a second fluid drop that has a size sufficient to form the desired pixel in combination with the first fluid drop.

Abstract

The accumulated charges on a substrate through handling or transport can affect the accuracy of the droplet deposition and hinder print precision and quality. To improve the accuracy of the droplet deposition and the print precision and quality, it is necessary to reduce the electrical field present between a printhead nozzle and a substrate surface. To achieve this purpose, a printing system including a fluid emitter and a conductive plate is developed, wherein the conductive plate supports a substrate onto which droplets are emitted, and is uniformly conductive within a printing region and/or grounded.

Abstract

In the field of an ink jet printer with multiple printheads, it can be necessary to precisely position nozzles relative to a substrate, where the nozzles are included in the printheads. It can be difficult to achieve a precision printing, unless the nozzles are precisely aligned relative to one another, if multiple printheads are used to print contemporaneously. A mounting assembly for a printhead assembly includes one or more active direction mounts, which can control the position of the printhead in one or more directions. It can allow dynamic nozzle and drop placement adjustment in one or more directions.

Abstract

A method and system of facilitating development of fluids having a variety of elemental compositions are disclosed. A graphical user interface allows user interaction with a lab deposition system to control fluid drop ejection of fluids through multiple nozzles. Fluid drop ejection and drop formation can vary from fluid to fluid, and require adjustments to waveform parameters of a drive pulse applied to the multiple nozzles. The system implements a drop watcher camera system to capture real-time still and video images of fluid drops as they exit the multiple nozzles. The captured drop formation of the fluid drops are displayed to the user, and based on the images the waveform parameters are adjusted and customized specific for individual fluid. In addition to adjusting the drive pulse that effects fluid drop ejection, a tickle pulse can also be adjusted and customize to prevent clogging of the nozzles.
