摘要
An image sensor includes (a) a first wafer having (i) a photosensitive area; (ii) a charge-to-voltage conversion region; (b) a second wafer having (i) a first amplifier that receives a signal from the charge-to-voltage conversion region; (c) an electrical interconnect connecting the charge-to-voltage conversion region to an input of the amplifier; (d) an electrically biased shield at least partially enclosing at least a portion of the electrical interconnect.
