  • Patent number: 8456410
    Abstract: Described herein are light sensors that primarily respond to visible light while suppressing infrared light. Also described herein are systems the incorporate such light sensors. Such a system can include a display, a light source to backlight the display and a controller to control the brightness of the light source based on feedback received from such light sensors. Described herein are also methods for controlling backlighting.

  • Patent number: 8309994
    Abstract: Embodiments of the present invention are directed to light sensors that primarily respond to visible light while suppressing infrared light. Such sensors are especially useful as ambient light sensors because such sensors can be used to provide a spectral response similar to that of a human eye. Embodiments of the present invention are also directed to methods of providing such light sensors, and methods for using such light sensors.

  • Patent number: 7609144
    Abstract: A thin film composition is made from silicon, an insulator such as alumina or silicon dioxide, and at least one additional material such as chromium, nickel, boron and/or carbon. These materials are combined to provide a thin film having a ? of at least 0.02 ?-cm (typically 0.02-1.0 ?-cm), and a TCR of less than ±1000 ppm/° C. (typically less than ±300 ppm/° C.). A sheet resistance of at least 20 k?/? may also be obtained. The resulting thin film is preferably at least 200 thick, to reduce surface scattering conduction currents.

  • Publication number: 20070059921
    Abstract: A semiconductor device interconnection contact and fabrication method comprises fabricating one or more active devices on a semiconductor substrate. A diffusion barrier layer is deposited over the devices, followed by an Al-based metallization layer. The diffusion barrier and metallization layers are masked and etched to define interconnection traces. Mask and etch steps are then performed to remove interconnection trace metallization that is in close proximity to the active device regions, while leaving the traces' diffusion barrier layer intact to provide conductive paths to the devices, thereby reducing metallization-induced mechanical stress which might otherwise cause device instability.
