摘要:
It relates to a method of manufacturing an electron source. In an activation process, a set value of an activation gas partial pressure is switched at multi-stages and an application of a compensation voltage is not conducted for a predetermined period after switching of the set value. Alternatively, the activation is repeated plural times while a row wiring or a column wiring is switched, and the application of the compensation voltage is not conducted for the predetermined period after switching of the row wiring or the column wiring. Thus, activation processing can be uniformly performed for all electron emitting devices.

In a method of fabricating an electron-emitting device, an activation step is performed in shorter time. The method forms a deposit of carbon or carbon compound on a precursory structure which becomes an electron-emitting region in an electron-emitting device made on a substrate and comprises a first step for depositing carbon or carbon compound in a gas atmosphere which includes a carbon compound of a first molecular weight, and subsequently a second step for depositing carbon or carbon compound in a gas atmosphere which includes a carbon compound of a second molecular weight smaller than the first molecular weight.
