ABSTRACT:
The surface of conductive silicon plate is scored with a grid of score lines, such that a plurality of small rectangular protrusions are formed. An insulating film is formed on the exposed surfaces of the rectangular protrusions. The conductive silicon plate is sliced through from the middle portion of each of the score lines to produce conductive silicon chips. The height of the rectangular protrusion defines a micro gap. The conductive silicon chip and two opposed electrodes contacted thereto are mounted in a glass tube having a reduced pressure therein.
