Optimized pixel isolation expertise enhances mild sensitivity and shade constancy

Credit score: Samsung

Samsung Electronics, a world chief in superior semiconductor expertise, immediately launched its new ‘ISOCELL Plus’ expertise, which permits CMOS picture sensors to seize extra mild, considerably growing mild sensitivity and shade constancy. Smartphone shoppers can now count on much more correct and clearer photographs in difficult mild environments.

To take high-quality pictures, CMOS picture sensors want to carry as a lot mild, or photons, as potential and transmit the suitable shade data to the photodiode. Such necessities have been resolved by the introduction of Samsung’s ISOCELL expertise in 2013. ISOCELL kinds a bodily barrier between the neighboring pixels, lowering shade crosstalk and increasing the full-well capability. This allows every pixel to soak up and maintain extra mild than the standard backside-illuminated (BSI) picture sensor design for superior picture high quality.

With the introduction of ISOCELL Plus, Samsung pushes pixel isolation expertise to a brand new degree via an optimized pixel structure. Within the current pixel construction, steel grids are shaped over the photodiodes to scale back interference between the pixels, which may additionally result in some optical loss as metals are likely to mirror and/or soak up the incoming mild. For ISOCELL Plus, Samsung changed the steel barrier with an revolutionary new materials developed by Fujifilm, minimizing optical loss and light-weight reflection.

“We worth our strategic relationship with Samsung and want to congratulate on the completion of the ISOCELL Plus growth,” stated Naoto Yanagihara, company vice chairman of Fujifilm. “This growth is a outstanding milestone for us because it marks the primary commercialization of our new materials. By steady cooperation with Samsung, we anticipate to deliver extra significant innovation to cellular cameras.”

The brand new ISOCELL Plus delivers greater shade constancy together with as much as a 15-percent enhancement in mild sensitivity. The expertise additionally permits picture sensors to equip zero.Eight-micrometer (µm) and smaller-sized pixels with none loss in efficiency, making it an optimum resolution for creating super-resolution cameras with over 20 megapixels.

“By shut collaboration with Fujifilm, an trade chief in imaging and data expertise, we’ve got pushed the boundaries of CMOS picture sensor expertise even additional,” stated Ben Okay. Hur, vice chairman of System LSI advertising and marketing at Samsung Electronics. “The ISOCELL Plus won’t solely allow the event of ultra-high-resolution sensors with extremely small pixel dimensions, but in addition deliver efficiency developments for sensors with bigger pixel designs.”
