"North America leads the backside illumination (BSI), complementary metal oxide semiconductor (CMOS) image sensor market, due to several design and technological improvements in this technology... The Asia-Pacific BSI CMOS image sensor market is expected to grow at the highest rate, in the coming years, due to which, it is expected to become the largest market, in the coming years. One of the key reasons for high growth of Asia Pacific in this market is its swift transition from analog to digital systems...
BSI CMOS image sensors eliminate the bulk substrate in the devices to decrease diffusion component of dark current and electrical crosstalk. BSI CMOS image sensors have higher quantum efficiency, which in turn enhances the production of output images with similar signal to noise ratio (SNR). However BSI CMOS image sensors are mechanically weaker, due to wafer thinning, which results in more chances of breakage for a large BSI CMOS image sensor."
