  • Patent number: 10705272
    Abstract: Systems and methods for optical imaging are disclosed. The optical fingerprint sensor includes an image sensor array; a collimator filter layer disposed above the image sensor array, the collimator filter layer having an array of apertures; and an illumination layer disposed above the collimator filter layer. The collimator filter layer filters reflected light such that only certain of the reflected light beams reach optical sensing elements in the image sensor array. Employing the collimator filter layer prevents blurring while allowing for a lower-profile image sensor.

  • Patent number: 9142696
    Abstract: A laser contact process is employed to form contact holes to emitters of a solar cell. Doped silicon nanoparticles are formed over a substrate of the solar cell. The surface of individual or clusters of silicon nanoparticles is coated with a nanoparticle passivation film. Contact holes to emitters of the solar cell are formed by impinging a laser beam on the passivated silicon nanoparticles. For example, the laser contact process may be a laser ablation process. In that case, the emitters may be formed by diffusing dopants from the silicon nanoparticles prior to forming the contact holes to the emitters. As another example, the laser contact process may be a laser melting process whereby portions of the silicon nanoparticles are melted to form the emitters and contact holes to the emitters.

  • Patent number: 9045653
    Abstract: Embodiments relate to printing features from an ink containing a material precursor. In some embodiments, the material includes an electrically active material, such as a semiconductor, a metal, or a combination thereof. In another embodiment, the material includes a dielectric. The embodiments provide improved printing process conditions that allow for more precise control of the shape, profile and dimensions of a printed line or other feature. The composition(s) and/or method(s) improve control of pinning by increasing the viscosity and mass loading of components in the ink. An exemplary method thus includes printing an ink comprising a material precursor and a solvent in a pattern on the substrate; precipitating the precursor in the pattern to form a pinning line; substantially evaporating the solvent to form a feature of the material precursor defined by the pinning line; and converting the material precursor to the patterned material.

  • Patent number: 8912890
    Abstract: The disclosure relates to surveillance and/or identification devices having capacitors connected in parallel or in series, and methods of making and using such devices. Devices with capacitors connected in parallel, where one capacitor is fabricated with a relatively thick capacitor dielectric and another is fabricated with a relatively thin capacitor dielectric achieve both a high-precision capacitance and a low breakdown voltage for relatively easy surveillance tag deactivation. Devices with capacitors connected in series result in increased lateral dimensions of a small capacitor. This makes the capacitor easier to fabricate using techniques that may have relatively limited resolution capabilities.

  • Patent number: 8822301
    Abstract: The present invention relates to electrically active devices (e.g., capacitors, transistors, diodes, floating gate memory cells, etc.) having dielectric, conductor, and/or semiconductor layers with smooth and/or dome-shaped profiles and methods of forming such devices by depositing or printing (e.g., inkjet printing) an ink composition that includes a semiconductor, metal, or dielectric precursor. The smooth and/or dome-shaped cross-sectional profile allows for smooth topological transitions without sharp steps, preventing feature discontinuities during deposition and allowing for more complete step coverage of subsequently deposited structures. The inventive profile allows for both the uniform growth of oxide layers by thermal oxidation, and substantially uniform etching rates of the structures. Such oxide layers may have a uniform thickness and provide substantially complete coverage of the underlying electrically active feature.

  • Publication number: 20130081677
    Abstract: Dopant ink compositions and methods of fabricating solar cells there from are described. A dopant ink composition may include a cross-linkable matrix precursor, a bound dopant species, and a solvent. A method of fabricating a solar cell may include delivering a dopant ink composition to a region above a substrate. The dopant ink composition includes a cross-linkable matrix precursor, a bound dopant species, and a solvent. The method also includes baking the dopant ink composition to remove a substantial portion of the solvent of the dopant ink composition, curing the baked dopant ink composition to cross-link a substantial portion of the cross-linkable matrix precursor of the dopant ink composition, and driving dopants from the cured dopant ink composition toward the substrate.
