Toshiba Announces Its First BSI Sensor

Toshiba announces its first BSI sensor. The 1/2.3-inch 14.6MP sensor is targeted to DSC and camera phones with video capability. The sensor is based on 1.4um pixels. Its video frame rate is 60fps at 1080p and 720p formats.

BSI approach is said to boost "light sensitivity and absorption by 40% compared to existing Toshiba products". Given already excellent QE numbers of Toshiba FSI sensors, I wonder how they can be improved by so much.

Sampling of the new sensor will begin in December and mass production will follow from the third quarter of 2010 (July—September). The new sensor will be produced at Toshiba's Oita Operations 300mm wafer lines deploying 65nm process technology. Initial production will be at a volume of 500,000 sensors a month.

Toshiba will continue to develop BSI products as a mainstream technology. CMOS image sensors are a focus product of Toshiba's System LSI business. Until now, their main application has been in mobile phones. With the new BSI sensors, Toshiba plans to expand their applications to include digital cameras.


  1. Actual QE curves? Dark current at 60C? Why 65nm process with BSI ... for smaller ckts?

  2. Sorry...forgot to add. According to 2009 workshop paper, it is SOI.
