Toshiba has just introduced a new CMOS sensor for smartphone including 8.08 million pixels of 1.2 microns. It would be the smallest pixels in the world, he said. To improve their sensitivity to light and sensor performance in general, it uses a so-called back-illuminated CMOS or BSI (Back-Side Illumination), the statement said.
Contains a CMOS transistors, and all cables from a substrate containing the photo-diodes that capture light. On a conventional sensor, the light passes through the lens, then the transistors to be finally captured by the photo-diodes, which is easier to manufacture. On a back-illuminated sensor (CMOS BSI), the substrate is placed before the layer of transistors, so that the light is not blocked.
