Samsung ISOCELL Technology

ISOCELL is the new advanced image sensor technology from korean giant Samsung for its next generation flagship smartphones. It substantially increase light sensitivity and controls the absorption of electrons to offer higher color fidelity even in poor lighting conditions. Samsung’s ISOCELL technology improves on current BSI (Back Side Illuminated) sensors by adding a physical barrier between the neighboring 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). In comparison to conventional BSI pixels, the ISOCELL pixels decrease the crosstalk by 30 percent which results in higher color fidelity to reproduce the original color. In addition to that, an imager designed with ISOCELL can feature a 20 percent wider chief ray angle (CRA) which reduces the height of camera module. The S5K4H5YB 8 Mega Pixel sensor will be the first sensor to use ISOCELL pixel. It features a 1.12um ISOCELL pixel and has a 1/4inch optical format. Samsung is currently developing S5K4H5YB sensor and the mass production is scheduled for Q4 2013. The new camera technology is expected to feature on Samsung’s next flagship smartphone Galaxy S5 which is expected to launch sometime during first half of 2014.
