Abstract
A vacuum field emitter device is manufactured by assembling elements of the device, including at least one getter, under a vacuum or a controlled atmosphere. The assembly step includes a step in which elements are positioned, an oven drying step and a device sealing step. Each getter is hydrogenated after the oven drying. The manufacturing process has applications in the manufacture of television screens.
