An image pick-up tube and a method of fabricating an image pick-up tube and a target section used therewith, in which the target includes at least a conductive film and a photoconductive film on a substrate for photo-electric conversion, and a signal from the target section is read by an electron beam scanning system. At least a part of the surface area outside the effective scanning region of the electron beam scanning side of the target section is formed of a secondary electron emission dampening layer.

Method of fabricating an image pick-up tube and target section used

A method of making an image pickup tube target (FIG. 1A), etc., using an amorphous photoconductive layer. When an electrode, an amorphous semiconductor layer, etc., are provided on a substrate, the steps of ion etching away a surface of the substrate and forming the electrode are performed so that a target (FIG. 1A) is produced in which no defects are substantially caused in a reproduced image even if a high electric field is applied across the target.
