Backside Illumination Technology

OmniVision Technologies, Inc., the largest CMOS image sensor manufacturer today, believes it has found an answer to the sensor shrinkage problem in a novel design that adopts backside illumination (BSI) technology.

Together with Taiwan Semiconductor Manufacturing Corp. (TSMC), OmniVision developed "process tweaks" that allow OmniVision to offer a CMOS sensor with improved image quality while extending its pixel roadmap down to 0.9 micron pixels, according to the company.

OmniVision said that it's ready to start sampling next month an 8-Megapixel product using the new BSI-based sensor design called OmniBSI.
