Title:
電子放出素子の製造方法、電子管の製造方法
Document Type and Number:
Japanese Patent JP4234748
Kind Code:
B2
Abstract:
A method for manufacturing an electron emitting device includes disposing a cathode substrate and an anode substrate to be faced to each other in a depressurized atmosphere containing an activation gas, the cathode substrate including a carbon layer formed by applying a paste having a fibrous carbon and carbon impurities on a cathode conductor and drying the coated paste. The method further includes applying a reverse bias voltage to the cathode conductor of the cathode substrate and an anode conductor of the anode substrate, thereby activating the carbon layer.
