Samsung has enhanced pixel technology for cmos image sensors

Samsung Electronics has introduced an advanced pixel technology for cmos image sensors, which it says increases light sensitivity and provides better colour fidelity in low light conditions.

Called Isocell, the patent pending technology forms a physical barrier between neighbouring pixels to enable more photons to be collected from the micro-lens and absorbed into the correct pixel's photodiode. According to Samsung, this minimises undesired electrical crosstalk between pixels and allows expanded full well capacity. Compared to conventional BSI pixels, the Isocell pixels have been shown to decrease crosstalk by approximately 30% and increase full well capacity by 30%. The first Samsung image sensor to adopt the new technology will be the S5K4H5YB, an 8MP imager with a 1/4inch optical format. The S5K4H5YB is currently sampling to customers with mass production scheduled for Q4.
