Sony Semiconductor Announces 4th Gen “Pregius S” Sensors


The newly developed Pregius S line is the 4th generation of Sony CMOS image sensors incorporating Pregius technology. The Pregius S reaches higher performance in a smaller package with stacked image sensor technology that is based on Sony’s proprietary Global Shutter function, and a back-illuminated pixel structure. This technology allows smart embedded applications in industrial vision to benefit from imaging performance that is improved by 1.7X, while the form factor of sensor design is reduced by 40 percent.

The Key Benefits of the New Preguis S Sensor Generation include:

  • Stacked image sensor technology improves imaging performance by 1.7X, while the pixel’s form factor is reduced by 40%
  • The back-illuminated structure reduces pixel size to 2.74µm, with uniform sensitivity and saturation
  • Increased quantum efficiency (+20%); improved saturation (+44%); and, greater dynamic range (+12%)
  • 2.4X faster output data rates leading to a significant boost in high-speed throughput

Sibel Yorulmaz-Cokugur, the Sensor Expert at FRAMOS, said, “Sony’s Semiconductor Solutions R&D department has achieved a perfect result with the 4th generation of CMOS Global Shutter sensors, based on their excellent technical expertise. The new Pregius S line combines improved performance together with miniaturization, and enables customers to leverage increased productivity and smart applications in Embedded Vision and Automation.”

Metal wiring in the new back-illuminated structure is placed under the photodiodes. Therefore, pixel size can be reduced from a conventional 3.45µm to 2.74µm, while maintaining sensitivity and saturation quality, and achieving 1.7 times higher resolution. Industrial applications benefit from performing product inspections at wider fields of view with increased accuracy and shorter measurement periods; additionally, this feature creates a 3X improvement in productivity and efficiency.

The new Pregius S line will be available in the Fall of 2019. The experts at FRAMOS are available to support customers with the integration of these new sensors into their applications and projects. Also for the Pregius S sensors, FRAMOS Engineering will offer services and IP around the SLVS-EC interface, such as their SLVS-EC IP core for Xilinx FPGAs.
