OmniVision Debuts Second-Generation PureCel®Plus and PureCel®Plus-S Technology and Product Families

BEIJING, China --- OmniVision Technologies, Inc. introduces its latest advancement in leading-edge pixel technologies: second-generation PureCel®Plus and PureCel®Plus-S. In keeping with OmniVision’s tradition of delivering industry-leading image sensors, the second-generation PureCel Plus technology offers significant improvements over the previous generation, such as higher full-well capacity (FWC), better sensitivity, increased signal-to-noise ratio (SNR) and enhanced low-light performance. Though the initial development was focused on supporting small-pixel products for mobile applications, this technology will ultimately benefit many other image sensor applications.

OmniVision’s second-generation PureCelPlus technology showcases various performance improvements, including:
• 20 percent increase in FWC, enabling higher dynamic range.
• A newly introduced composite metal grid (CMG) structure, which increases pixel quantum efficiency and enhances sensor low-light performance, leading to a 12.5 percent improvement in sensitivity.
• Improved deep trench isolation (DTI) structure, which further reduces color crosstalk and improves the SNR10 (low-light performance index) number by 10 lux.
• These structure improvements also enable small-pixel sensors to have better tolerance to incident light angles. This in turn allows imaging systems to use lower F-number lenses for better brightness, and to realize lower module heights that are essential for slimmer phone designs.

OmniVision’s second-generation PureCel Plus-S technology will empower new families of compact 20-megapixel and 16-megapixel sensors. The 20-megapixel OV20880 and OV20880-4C and the 16-megapixel OV16885 and OV16885-4C are designed to deliver high-resolution images to high-end smartphones across a variety of lighting conditions.

The OV20880, OV20880-4C, OV16885 and the OV16885-4C are currently available for sampling and are expected to enter volume production in the first quarter of 2017.
