Sony's announces its new back-illuminated CMOS image censor

Sony has announced a new back-illuminated CMOS image sensor that will improve the still picture quality in still cameras and camcorders. This new back-illuminated CMOS image sensor comes with 1.75┬Ám square pixels, five effective mega pixels, 60 frames/s. The image sensor has nearly twofold sensitivity and low noise and other enhanced imaging properties which has been achieved by illuminating the backside of the silicon substrate. Gizmodo reports:

In the new design, however, most of the photons goes through the on-chip lens and color filter directly into the new photo-diode structure, while the transistor layer sits at the bottom of the sensor. According to Sony, "that achieves a higher sensitivity of +6dB and a lower random noise of -2dB without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure."

Sony is planning on introducing the new technology in their next generation cameras, and hopefully we will see it in other products, especially cellphones.

The best thing about Sony Ericsson phones is that each of the phones fulfills different requirements of the users. Sony Ericsson walkman phone is the ultimate gadget for music lovers. On the other hand, if you enjoy taking pictures, then Sony Ericsson Cybershot is the best buy for you. This new technology will definitely be a big boost for Sony Ericsson cyber shot phones, cameras and handy cams.
