Samsung Expands Advanced 0.7µm-Pixel ISOCELL Image Sensor Offerings for Wider Mobile Applications
Samsung (News - Alert) Electronics Co., Ltd., a world leader in advanced semiconductor technology, today introduced four new Samsung ISOCELL image sensors for its 0.7 micrometer (µm)-pixel product lineup; 108-megapixel (Mp) ISOCELL HM2, 64Mp ISOCELL GW3, 48Mp ISOCELL GM5 and 32Mp ISOCELL JD1. With the new 0.7µm ISOCELL technology, Samsung plans to expand the ultra-high-resolution offerings 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. With pixels at 0.7µm, Samsung's newest image sensors are up to 15-percent smaller than the 0.8µm sensors of the same resolution and reduce the height of the camera module by up to 10 percent . Smaller form factors give smartphone manufacturers more flexibility, such as added features or more streamlined designs, when developing their next-generation devices.
To collect an ample amount of light and increase the full well capacity despite the minute pixel sizes, Samsung has incorporated its advanced ISOCELL Plus and Smart-ISO technologies, especially optimizedfor 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.

* Samsung first announced its ISOCELL technology in 2013, which reduces color crosstalk between pixels by placing a physical barrier, allowing small-sized pixels to achieve higher color fidelity. Based on this technology, Samsung introduced the industry's first 1.0µm-pixel image sensor in 2015 and a 0.9-pixel sensor in 2017. In June 2018, Samsung introduced an upgraded pixel isolation technology, the ISOCELL Plus.
