Well, 2 days ago Samsung announced the world's first 3.0-megapixel CMOS image sensor (CIS) with a 1/4-inch lens aperture. It is very well fit for ultra slim camera phones. Samsung's new 1.75um-size pixel gives users the possibility with 1/4-inch lens aperture to drastically reduce the camera module size by 30 percent. Also we can mention that there is no degrading in the picture quality with the 1.75um pixel, 1/4-inch lens aperture 3M-pixel CIS. The new CIS chip provides a small form factor and high picture quality.
By means of 90-nanometer (nm) process technology, Samsung is going to mass produce the new 1.75um pixel, 1/4-inch lens aperture 3-Mp CIS in the first quarter of 2007. The new CIS chip uses Samsung's proprietary 90nm copper technology that reduces the distance between the micro-lens to the photo diode that results in maximizing the light-gathering efficiency to overcome the potential decline of image quality as the pixel size scales down.
3M-pixel and higher resolution phones are expected to take up 13 percent of total camera phones.
