Toshiba Corp., Tokyo, Japan, announced the launch of a new 8 megapixel, 1.12 micrometer pixel CMOS image sensor, offering what the company claims is the industry’s smallest level pixel size with enhanced sensitivity and improved imaging performance of back-side illumination technology (BSI). Sampling of the new sensor will begin at the end of this month and mass production will follow from the end of 2011.

BSI sensors deploy lenses on the rear of the sensor, on its silicon substrate, not on the front, where wiring limits light absorption, says the company, noting this positioning boosts light sensitivity and absorption, and allows formation of finer image pixels in smaller CMOS image sensors, bringing it more suitable for motion pictures applications as well. Toshiba expects BSI CMOS image sensors to become the mainstream technology in portable digital technology, with applications expanding from mobile phones and digital cameras to smartphones and tablets.
