Abstract
A method of making a backside illuminated image includes forming a device on the frontside of thin device layer provided on an oxide layer which is mounted on a sacrificial substrate and bonding the front side of the device layer to a permanent silicon support substrate. Thereafter, the oxide layer and sacrificial layer are removed by chemical etching to expose the backside of the thin device layer.
