  • Publication number: 20150263122
    Abstract: The present disclosure relates to a method of forming a FinFET device having sidewalls spacers comprising an air gap that provides for a low dielectric constant, and an associated apparatus. In some embodiments, the method is performed by forming a fin of semiconductor material on a semiconductor substrate. A gate structure, having a gate dielectric layer and an overlying gate material layer, is formed at a position overlying the fin of semiconductor material. Sidewall spacers are formed at positions abutting opposing sides of the gate structure. Respective sidewall spacers have a first layer of insulating material abutting the gate structure and a second layer of insulating material separated from the first layer of insulating material by an air gap. By forming the FinFET device to have sidewall spacers with air gaps, the parasitic capacitance of the FinFET device and a corresponding RC time delay are decreased.

  • Publication number: 20150228731
    Abstract: Some embodiments relate to an integrated circuit (IC) including one or more finFET devices. A finFET includes a fin of semiconductor material extending upwards from a semiconductor substrate. First and second source/drain regions, which have a first doping type, are spaced apart laterally from one another in the fin. A channel region is disposed in the fin and physically separates the first and second source/drain regions from one another. The channel region has a second doping type opposite the first doping type. A conductive gate electrode straddles the fin about the channel region and is separated from the channel region by a gate dielectric. A shallow doped region, which has the first doping type, is disposed near a surface of the fin around upper and sidewall fin regions. The shallow doped region extends continuously under the gate electrode between outer edges of the gate electrode.

  • Publication number: 20140160392
    Abstract: The present invention provides an optical fiber for backlight module, the optical fiber being a spiral, including: light-incident part to guide in light, near light-incident part close to light-incident part, and faraway light-incident part away from light-incident part; pitch and/or spiral radius of spiral optical fiber gradually decreasing from near light-incident part towards faraway light-incident part. The present invention also provides backlight module and LCD. With spiral optical fiber to guide in light from light source (e.g., LED or CCFL), backlight module and LCD use optical fiber as backlight source of backlight module to separate light and heat inside backlight module to avoid heat-dissipation problem. As such, the present invention effectively improves life span, optical characteristics and reliability of backlight module. Because light source is not inside backlight module, the known heat-dissipation means can be applied to increase life span of light source.

    Abstract: A method and apparatus for gray level dynamic switching. The method is applied to driving a display with at least one pixel. In the method of the present invention, a gray level sequence SG is provided. SG sequentially represents two or more desired gray levels Go(1), . . . , Go(T) of the pixel at consecutive time frames 1, . . . , T and comprises a current gray level Go(t) and a previous gray level Go(t?1) corresponding to time frames t and t?1, respectively. Then, the pixel is driven with an optimized driving force Vd(t) to change the pixel forward to a state corresponding to Go(t) according to Go(t) and Go(t?1). In the present invention, the optimized driving voltage Vd(t) is determined by equations of Vd(t)=Vo(t?1)+ODV and Vd(t)=a×Gd(m)3+b×Gd(m)2+c×Gd(m)+d, wherein the voltage ODV is a minimum voltage capable of obtaining one gray level transition in a determined response time.
