What is backside illumination?
It was listed under camera specs on iPad mini. I just assumed that it meant an LED like the iPhone has. So what is this feature exactly?

Backside illumination just means the wiring goes behind the light sensor meaning there is less to obstruct the light flow in front of the sensor and therefore this means more of the light from the scene you are imaging is captured by the sensor.
The main benefit of this method is that more light captured means less need to amplify the signal which in turn means you get less noise (grain) in the captured image - especially noticeable in poorer light conditions.
