Today Toshiba announced the launch of a new CMOS image sensor that brings 14.6 million pixels to digital still cameras and mobile phones supporting video imaging. The sensor, the latest addition to Toshiba’s “DynastronTM” line-up, is also the company’s first to integrate the enhanced sensitivity offered by backside illumination technology (BSI). Sampling of the new sensor will begin in December, and mass production will follow from the third quarter of 2010 (July–September).

BSI brings new levels of responsiveness to CMOS imaging. Lenses are deployed on the rear of the sensor on the silicon substrate, not on the front, where wiring limits light absorption. This positioning boosts light sensitivity and absorption by 40% compared to existing Toshiba products, and allows formation of finer image pixels.

Toshiba has made full use of the advantages of BSI to realize image pixels with a pitch of 1.4 microns, and to pack 14.6 million of them into a 1/2.3-inch sensor that meets the high level imaging and processing requirement, and that will also bring a new level of image quality to mobile phones. Toshiba will use the new sensor to promote its full-scale entry to the digital camera market, and will continue to develop BSI products as a mainstream technology.
