摘要:
An image pickup tube is manufactured by setting a PN junction type semiconductor target having a resistive sea made of cadmium telluride in a glass envelope and heating the envelope at 120*C to 400*C to effect evacuation.
摘要:
An image intensifier vidicon which is divided by a semiconductor target into an image section, the inner surface of the face plate of which is coated with an electron-emissive layer and a scanning section, wherein said semi-conductor target includes a semiconductor substrate, a plurality of PN junctions formed therein, an accelerating layer formed on the electron incident side of said target, and a scanning surface which is protected from contamination by alkali metals constituting the electronemissive layer by means of insulation rings provided in the scanning section. One of the insulation rings also set the critical spacing between the target and a mesh electrode.
摘要:
A photoelectric converting device comprising a semiconductor substrate in one surface of which there are provided a plurality of junctions in a mosaic arrangement. In the portions of the opposite surface of said substrate which are in registration with and face said junctions is provided means to decrease effectively the surface recombination of minority carriers created due to the introduction of a light.
