Abstract
In a method of manufacturing a raster transfer image sensor, the charge transport channels and the channel-bounding regions and the vertical anti-blooming channels are formed in a self-registering manner in that the channel-bounding regions are provided via a mask, and the intervening charge transport channels are provided in a maskless doping step. Since this doping is also carried out in the channel-bounding regions, a doping profile favorable for the photosensitivity is obtained in the channel-bounding regions with a maximum concentration at a distance from the surface.
