Abstract
Charge integration is selectively interrupted in a semiconductor imager with thinned substrate, by modulating the electric field normal to its back-illuminated surface. This suppresses smear generated during field transfer in certain types of imager when exposed to high-energy images, for example. The thinned substrate is cemented with an electrically insulating epoxy to a glass backing plate bearing a transparent electrode, the potential on which is varied to modulate the drift field.
