摘要:
The present invention relates to a segregation reducing agent consisting of curdlan and alkaline materials and a hydraulic composition containing the segragation reducing agent, particularly, the present invention relates to the segregation reducing agent prepared by alkalifying a curdlan-producing fermentation broth per se or a curdlan powder with an alkaline material, and also relates to hydraulic compositions, concrete and mortar, comprising the segregation educing agent. This segregation reducing agent can provide a great segregation reduction effect for hydraulic compositions even at its small amount as well as guarantee the strength, filling ability and fluidity.

摘要:
Image sensors and methods of fabricating the same are provided. The image sensor includes a blocking pattern disposed on photodiodes. The blocking pattern is formed of insulation material having a metal diffusion coefficient which is lower than a silicon oxide diffusion coefficient. Therefore, dark defects of the image sensor are reduced. In addition, the image sensor includes a color-ratio control layer. The color ratio control layer controls color ratios between the sensitivities to blue, green and red. As a result, color distinction of the picture that is embodied by the image sensor can be improved.
摘要:
An image sensor includes an active pixel and a black pixel. The active pixel has a first signal gain and a first dark signal level, and the black pixel has a second signal gain and a second dark signal level. At least one of the first and second signal gains is adjusted such that the first and second dark signal levels are substantially equal for minimizing image defects in the image sensor.
摘要:
Unit pixels, image sensors and methods for fabricating the image sensor are provided. A unit pixel includes: a photodiode for accumulating photocharges; a floating diffusion region for detecting the photocharges accumulated in the photodiode; a reset element for periodically resetting the floating diffusion region; a drive element for amplifying the photocharges accumulated in the floating diffusion region; a selection element for selecting the unit pixel; and a silicide layer formed on top surfaces of the transfer gate. The photocharges are transferred to the floating diffusion region via a transfer gate.
