Talk:Back-illuminated sensor

Little mention of OmniVision's role
I noticed that the text only focused on Sony's BI sensors, but it was OmniVision which was first to market, so I added text to give OmniVision credit in being the first to commercialize the technology.

Text of merged article, Backside illumination
Backside illumination (BSI or BI) is a technology for image sensors, either CMOS or CCD. This is better known as "Back Thinned" when referring to CCD or CMOS technology, e.g. Back thinned CCD or back thinned CMOS. In a device with backside illumination, the silicon light sensor for each pixel is on the "back" side of the silicon wafer, opposite the transistors and metal wiring layers. This increases the efficiency of the sensor as compared to the traditional ("frontside illumination") technology, in which some of the light is scattered by the circuit layers on the front side of the wafer before it can reach the image sensor.

Numerous scientific cameras use this technique to increase efficiency from ~60% to >90%, making it useful in low-light situations. Innovations in manufacturing have added this to consumer grade devices, such as the iPhone 4 and the HTC Evo 4G.
