摘要：
We present the application of micromachining technology to silicon-based field emission devices. Silicide formation on the emitter is shown to lead to lower voltage emission. Integration of series resistors and heaters is achieved by silicon bulk-micromachining. Multiple levels of tungsten electrodes are integrated by surface micromachining. This allows the integration of an entire micromachined electron gun array (MEGA) on a single silicon substrate. We review simulation results to illustrate the electron-optical properties of MEGA and show fabrication results and emission data.
