<p>PURPOSE:To provide a detection method for ensuring the easy determination of a field emission element shortcircuited between an emitter and a gate, and a field emission element drive method for ensuring the easy design and manufacture of a fuse connected for separating a shortcircuited element, and the proper blowing of a fuse connected to a shortcircuited element, regarding a field emission element. CONSTITUTION:This is a method for detecting a shortcircuit in an field emission element having an emitter 2 and a gate 3 around the emitter 2 for externally introducing an electron beam on field emission from the emitter 2 via the application of forward bias. Also, constitution is so made that inverse bias is applied whenever necessary between the emitter 2 and the gate 3, and current at the time of inverse bias application is measured.</p> |
