Title:
MANUFACTURE OF ELECTRON SOURCE, ELECTRON SOURCE MANUFACTURED BY THIS MANUFACTURING METHOD AND IMAGE FORMING DEVICE USING THIS ELECTRON SOURCE
Document Type and Number:
Japanese Patent JP3205167
Kind Code:
B2
Abstract:
PURPOSE: To provide an electron source having a uniform electron emitting characteristic by having a current carrying forming process, performed by dividing a plurality of surface conduction type electron emitting elements into a plurality of groups, in a process of forming an electron emitting part.
CONSTITUTION: Lower wiring, interlayer insulating layer, upper wiring, element electrode, electron emitting part forming thin film, etc., are formed on an insulating board, to prepare a power supply board applying forming non-processed simple matrix wiring. Each surface conduction type emitting element D (1, 1) to D (6, 6) is connected to matrix wiring DX1 to DX6 and Dy1 to Dy6. Now, a ground level is applied to the wiring DX3, and on the other hand prescribed potential is applied from a voltage source VE to except the DX3 of the X direction wiring, simultaneously with applying potential from VE to also the Dy1 to Dy6. As a result, to both ends of the selected D (1, 3) to D (6, 3), voltage is applied to perform forming. On the other hand, in the other element, no forming is performed, to generate no deterioration and damage at all on the thin film.
