What benefits has OmniVision adopted 8 megapixel backside illumination (BSI) sensor got?

The world is always trying to push the Megapixel to new heights in the way of cameras, but how far can they go and how can they push things to another level.

Well OmniVision claim that their 8 megapixel OmniBSI sensor will turn mobile phone/cell phone imaging world upside down, everyone knows for a fact that getting as many pixels into rapidly shrinking sensors is the way to go and how small they go only the future will tell, the question has to be by stuffing as many pixels into smaller sensors would this give us poor performance of poorly lit images of increasingly low quality?

Anyway back to the news of OmniVision who are the CMOS image sensor manufacturer of today, OmniVision claim that they have solved the pixel problem that adopts backside illumination (BSI) technology. Now we get a little technical because we want to explain a little about BSI, is short backside illumination (BSI) will help maximize photon collection by circumventing obstructive metal and dielectric layers on the top-side of the sensor die which means the result will give a much more improved light absorption, increased sensitivity and F stops with reduced crosstalk and thinner overall camera modules. What we like is the fact the source below EETimes has said that BSI is not a new technology and that many manufacturers lay claim to BSI patents.

OmniVision however do seem to be the first to take this high technology to the mass market for mass production and that they will release an 8 megapixel OmniBSI CameraChip sensor with the new tech for sample sometime in June. Now this maybe good for digital cameras but where does it lie in the mobile camera phone world?
