ABSTRACT:
An integrated circuit electronic grid device includes first and second metal layers wherein a layer of a dielectric medium is disposed between the metal layers. A third metal layer is disposed above the second metal layer and insulated from the second metal layer by another layer of a dielectric medium. The first and second metal layers are biased with respect to each other to cause a flow electrons from the first metal layer toward the second metal layer. The second metal layer is provided with a large plurality of holes adapted for permitting the flow of electrons to substantially pass therethrough and to travel toward the third metal layer. A fourth metal layer is disposed above the third metal layer to collect the electrons wherein the third metal layer is also provided with a large plurality of holes to permit the electrons to flow therethrough and continue toward the fourth metal layer. The third metal layer is coupled to a lead to permit it to serve as a control grid for modulating the flow of electrons.
