Samsung Advanced 0.7μm-Pixel ISOCELL Image Sensor Boast Industry’s Smallest Pixel Sizeby dhiram
Samsung 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. Last year, Samsung introduced the industry’s first 0.7μm-pixel image sensor and the first 108Mp sensors. Now Samsung is 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. 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 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. Samsung ISOCELL HM2, GW3 and JD1 are currently in mass production, and the company is sampling GM5.
