Samsung Launches Industry's First APS-C Format 28-megapixel BSI CMOS Image Sensor

    Good afternoon, Habr!

    Samsung Electronics has announced the 28-megapixel APS-C CMOS image sensor for digital cameras - S5KVB2. The new sensor has already gone into mass production - it was supplied with the new Samsung NX1 compact camera, which was presented last week at the Photokina 2014 exhibition in Cologne, Germany.


    The basis of Samsung’s new development lies in the use of pixel backlight technology, which made it possible to increase the photosensitivity of each pixel and increase peripheral light absorption by 30%, and therefore provide clearer and better images. Metal layers are formed from copper, using a 65-nanometer process technology with reduced power consumption. This provides the S5KVB2 with a tangible advantage over today's most common image sensors, which are manufactured using a 180-nanometer process technology using aluminum conductors, namely, a significant reduction in power consumption and heat dissipation. Thanks to the new process technology and integrated circuit architecture, the S5KVB2 image sensor also significantly reduces noise during operation.

    Since the metal layers are under the photodiodes, Samsung engineers got more freedom in the process of designing their topology, which, ultimately, allowed to increase the consistent reading speed. Due to its design features, the new S5KVB2 sensor allows not only to receive high-quality photos, but also to shoot UHD video at a speed of 30 frames per second.
