Samsung introduced four new Samsung ISOCELL image sensors for its 0.7 μm-pixel product lineup. With the new 0.7μm ISOCELL technology, Samsung plans to expand the high resolution sensors to mainstream smartphones.

“Samsung continues to pioneer innovations, such as ISOCELL Plus and Smart ISO, to deliver more pixels in a smaller package,” said Yongin Park, executive vice president of the sensor business at Samsung Electronics. “Last year, Samsung introduced the industry’s first 0.7μm-pixel image sensor and the first 108Mp sensors. Now we are bringing more of the advanced pixel technologies to mobile cameras in a variety of options that will enable high-resolution images and sleeker designs in a wider selection of tomorrow’s mobile devices.”

For ultra-high-resolution image sensors, even a mere 0.1μm-difference per pixel can have a significant impact on the overall size of the sensor as well as the height of the camera module. Samsung’s newest image sensors with pixels at 0.7μm are up to 15% smaller than the 0.8μm sensors of the same resolution and reduce the height of the camera module by up to 10%. This even smaller size enables smartphone manufacturers to design their product with more flexibility.

To collect an ample amount of light and increase the full well capacity despite the minute pixel sizes, Samsung has incorporated its ISOCELL Plus and Smart-ISO technologies, especially optimized for 0.7μm. ISOCELL Plus retains the received light with a wall-like structure around the pixel while Smart-ISO makes full use of the incoming light by intelligently adjusting the ISO accordingly for optimal exposure.

In the latest 0.7μm products to be introduced later this year, Samsung will start rolling out an enhanced pixel technology, ISOCELL 2.0, which allows excellent performance despite the challenges with decreasing pixel sizes. The new technology further enhanced the wall structure between cells, resulting in added light sensitivity of up to 12 percent compared to the current ISOCELL Plus technology.
