Abstract
A charge transfer device having an improved signal stage is disclosed. This stage includes a floating region formed in a semiconductor layer and receiving signal charges from a charge transfer stage, a reset drain region formed in the semiconductor layer adjacently to the floating region, a reset gate for resetting the floating drain region in potential to the reset drain region, an absorption region formed in the semiconductor layer adjacently to the reset drain region, a barrier gate supplied with a constant voltage to form a channel region between reset drain region and the adsorption region, and a charge injection source connected to the reset drain region to inject charges thereinto.
