ABSTRACT:
A first laminated sub-structure having a semiconductor substrate, a lower insulating layer on the semiconductor substrate, emitter electrodes formed in micro-apertures in the lower insulating layer and a gate electrode on the upper surface of the lower insulating layer is aligned with a second laminated sub-structure having a transparent upper insulating layer and a grid member on the transparent upper insulating layer by means of a stepper, and the first and second laminated sub-structures are fixed to each other through a field assisted glass-metal sealing technique.
