Samsung's 3Mpixel CMOS image sensors

Samsung Electronics Co. Ltd says it has introduced the industry's first 3Mpixel CMOS image sensor (CIS) with a 1/4-inch lens aperture that delivers digital still camera picture quality to mobile handsets.

Suitable for ultraslim camera phones, the 1.75µm pixel, 1/4-inch lens aperture CMOS image sensor combines Samsung's high-resolution sensor technology with a high-speed interface, while reducing the camera module size by 30 per cent as compared to a conventional 2.25µm pixel, 1/3-inch 3Mpixel CIS. The small form-factor also allows the new CMOS image sensor to replace a 1/4-inch, 2Mpixel CIS module because they share the same footprint size.

The 1.75µm pixel, 1/4-inch lens aperture 3Mpixel CIS shows no deterioration in picture quality compared to a 2.25µm pixel, 1/3-inch lens aperture 3Mpixel CIS, according to the company.

Mass production of the 1.75µm pixel, 1/4-inch lens aperture 3Mpixel CIS is expected in Q1 2007. The device will be produced using Samsung's proprietary 90nm copper process technology, which is said to reduce the distance between the micro-lens to the photo to overcome the potential decline of image quality as the pixel size scales down.
