Abstract
A method of fabrication of non-linear control elements as applicable to electrooptical displays and in particular to large-area liquid-crystal displays of the flat-panel type, in which the following layers are stacked successively on a substrate: a first layer of metallic material, a first layer of undoped amorphous semiconductor material, a layer of doped amorphous semiconductor material, a second layer of undoped amorphous semiconductor material, and a second layer of metallic material.
