Samsung Launches ISOCELL: Innovative Image Sensor Technology for Premium Mobile Devices
Press Release, News
Samsung Electronics Co., Ltd., a world leader in advanced semiconductor solutions, today announced its new advanced pixel technology for CMOS image sensors, ISOCELL. This new technology substantially increases light sensitivity and effectively controls the absorption of electrons, resulting in higher color fidelity even in poor lighting conditions. ISOCELL improves the image quality and enhances the user experience of premium smartphones and tablets that integrate sensors with this exciting new technology.
"Through advances in pixel and process technology, smartphone and tablet cameras have made it easier than ever for consumers to capture and share beautiful, clear images with the world," said Taehoon Kim, vice president of System LSI marketing, Samsung Electronics. "ISOCELL technology is yet another innovation that significantly raises the bar in image quality, and demonstrates Samsung's technology leadership in image sensors for mobile devices."
The quality of an image sensor is determined by the amount of light that is accurately captured by the individual pixels within the sensor array. With the market pressure to increase camera resolution and image quality, without growing the camera size, the pixels have had to shrink, while improving their performance at the same time - a challenging task.
To meet this challenge, previous sensor technology developments focused on improving the light absorption of each pixel, and have progressed pixel technology from FSI (Front Side Illumination) to BSI (Back Side Illumination) which places photodiode at the top to maximize photoelectric efficiency. While being very effective at the time, this BSI technology also faced limitations in improving image quality as pixel sizes continued to decrease.
Building on these past advances and continuing the push toward higher quality image sensors for mobile devices, Samsung has developed ISOCELL the next generation of pixel technology, which is patent pending. ISOCELL technology forms a physical barrier between neighboring pixels - isolating the pixel. This isolation enables more photons to be collected from the micro-lens and absorbed into the correct pixel's photodiode minimizing undesired electrical crosstalk between pixels and allowing expanded full well capacity (FWC).
