ABSTRACT:
A vacuum state microelectronic device comprising at least a cathode, an anode, and a grid, disposed in a cavity, and formed by the wafer bonding of two planar substrates. The technology permits multiple vacuum state microelectronic devices (vacuum tubes) to be arrayed on a single substrate in an integrated manner. So as to form a bond as strong as the substrate itself.
