Sony is going to have the capacity for so-called stackedcmos image sensors to expand. Such sensors will find their way to tablets and smartphones. With the expansion involved an amount of approximately 794 million euros.
With the investment wants of Sony, the production capacity in three production facilities in Nagasaki expand. With the money include new wafer fabrication equipment and new production lines for stacked-cmos-image sensors opened. The investments relate to the first half of the current financial year ended 31 march 2013 ends, until the end of the next financial year. With the expansion, the total production capacity for cmos and ccd image sensors in september 2013 increased to 60,000 wafers per month.
At Sony’s ‘stacked’ cmos beeldsensortechnologie is the so-called aperture ratio, i.e. the ratio between the photosensitive part of the pixel and the total pixeloppervlak, enhanced by the analog hardware is no longer a space next to the light-sensitive layer, but underneath it is placed.
Sony announced on January 23 this year, three cmos image sensors, which make use of the stacked cmos structure. Two of them, a 1/4″sensor with 8 megapixels and a 1/3″sensor with 13 megapixels, have the rgbw pixels, wherein the white subpixel is meant for better light sensitivity. The third stacked-cmos-image sensor is a 1/4″-variant with 8 rgb pixels. All three relate to the bsi sensors, where the bedradingslagen under the fotodiodes.
