Abstract
A method of fabricating a backside-illuminated pixel. The method includes forming frontside components of the pixel on or in a front side of a substrate, the frontside components including a photosensitive region of a first polarity. The method further includes forming a pure dopant region of a second polarity on a back side of the substrate, applying a laser pulse to the backside of the substrate to melt the pure dopant region, and recrystallizing the pure dopant region to form a backside doped layer. Corresponding apparatus embodiments are disclosed and claimed.
