Abstract
The disclosure concerns the making of microcomponents belonging to the family of vacuum tubes of the diode, triode and electroluminescent component type. The goal thereof is notably to resolve problems of fabrication under vacuum, and of precise anode-cathode spacing. This goal is achieved by means of a microcomponent of the stacked structure type wherein the anode is made in the form of a metallic layer for the sealing of said cavity under vacuum containing the microcathode, and wherein at least one solid dielectric layer provides for the spacing between said anode and said microcathode.
