Method and apparatus for manufacturing image displaying apparatus

A method of manufacturing an image displaying apparatus, comprising the steps of:

• a:
• disposing a substrate, on which an electrical conductor and a wiring connected to the conductor are formed, on a support;
• disposing a container on the substrate so as to form a sealed gas-tight atmosphere defined by the container and the substrate, to cover the conductor with the container, except for part of the wiring;
• setting the container into a desired atmosphere therein;
• and applying a voltage to the conductor through the part of wiring, thereby forming at least one electron-emitting device at a part of the conductor to thereby form an electron source substrate;
• b:
• preparing a phosphor substrate on which a phosphor emitting light responsive to an irradiation with an electron emitted from the electron-emitting device is arranged, and disposing the electron source substrate and the phosphor substrate within vacuum atmosphere;
• c:
• carrying under a vacuum atmosphere one or both of the electron source substrate and the phosphor substrate into the vacuum atmosphere in a gettering process chamber, and subjecting to a gettering process only one substrate carried therein, or the one or both of the substrates carried therein;
• and
• d:
• after the gettering process, carrying under the vacuum atmosphere the electron source substrate and the phosphor substrate in a seal-bonding process chamber, and subjecting to heat seal-bonding the substrates in an opposing state.
