Samsung’s new backside illumination CMOS sensor
Google translation:
"Korean Samsung Electronics Co., Ltd. Is, CMOS back radiation can increase the sensitivity of the sensor (BSI: backside illumination) to commercialize a technology to mass-produce the product was 2010. Now, CMOS sensor all three major companies back to 2010 was irradiated with CMOS sensor technology (BSI CMOS type sensor) will begin mass production. Samsung is the appropriate approach to adopt low-cost process technology."
Sony already has a backside illuminated sensor (see here and here for more info) in two of their p&s models (Sony WX1 and Sony TX1). It seems that Samsung will also use their sensor for smaller cameras. Introducing this technology to a DSLR camera may not be appropriate based on this interview with Sony’s CMOS Exmor R sensor developers.
