  • Patent number: 7074099
    Abstract: A polymer or organic light emitting display may be formed on a substrate by patterning the light emitting material using a screen printing technique. In this way, displays may be formed economically, overcoming the difficulties associated with photoprocessing light emitting materials. A binary optic material may be selectively incorporated into sol gel coatings coated over light emitting elements formed from the light emitting material. A tricolor display may be produced using a light emitting material that produces a single color.

  • Patent number: 6753922
    Abstract: An imaging system includes an image sensor that is attached to a circuit board via a mass reflow process. The image sensor captures image data and provides the image data at an output of the imaging system. In one embodiment, the image sensor uses a color filter array (CFA) material that is substantially stable through the mass reflow process.

  • Patent number: 6665014
    Abstract: An array of photosensitive devices may be formed with improved fill factors by including a diffractive microlens which may have a stepped configuration. The microlens may be formed of a sol-gel material having a photoinitiator, or other materials that may be defined with low temperature techniques commonly used in connection with photoresist. In particular, a gray scale mask may be used to define a plurality of steps in the resulting microlens which have different diffractive characteristics.

  • Patent number: 6611036
    Abstract: A photosensitive device with a microlens array may be packaged for surface mount packaging and subsequent mass reflow processing without significantly degrading the optical performance of the microlens. The microlens may be formed using a series of heat steps of increasing time and temperature. In addition, the microlens may be bleached to prevent degradation of its optical transmissivity at temperatures normally associated with surface mount techniques.

  • Patent number: 6194704
    Abstract: An photosensitive device may be formed with a diffractive lens which offsets chromatic aberrations and dispersion caused by a refractive capture lens. The diffractive lens may be formed of a sol-gel material having a photoinitiator, or other materials including those that may be defined with low temperature techniques commonly used in connection with photoresist.

  • Patent number: 6166369
    Abstract: A microcollector for photosensitive devices such as imaging arrays for digital cameras, scanners and other devices, may be formed on a semiconductor structure adjacent to a photosensitive element. The collector may include reflective surfaces arranged about the photosensitive element so as to reflect incident light towards the photosensitive element. The collector may be used in conjunction with a refractive/diffractive microlens to further focus light onto the photosensitive element. As a result, the fill factor of the photosensitive device may be improved, and the signal to noise ratio may also be enhanced.
