Toshiba America has announced the launch of a new CMOS image sensor, one apparently offering the industry’s smallest pixel size (1.12 micrometers) with enhanced sensitivity and improved imaging performance though the use of back-side illumination technology (BSI).
Toshiba expects BSI CMOS image sensors to become a mainstream technology in a variety of portable digital devices, such as mobile phones, digital cameras, smartphones, and tablets.
BSI technology puts the lens on the rear of the sensor, on its silicon substrate, not on the front, where wiring limits light absorption. This positioning, says Toshiba, boosts light sensitivity and absorption, and allows the company to make finer quality image pixels in smaller-sized CMOS image sensors.
This, it notes, makes these BSI CMOS image sensors more suitable for video applications, such as video capture or video chat.
The first product in Toshiba’s new line of BSI CMOS image sensors will have a .25-inch optical format and 8 megapixels, supporting video capture at up to 60 frames-per-second in both 1080p and 720p high-definition.
Ever wonder how much that imaging sensor costs, how much it contributes to the total cost of the device using it? Toshiba says samples are priced at $15 per unit.
