Abstract
In a method of fabrication of non-linear control elements for a flat display screen of the liquid crystal type, successive layers of n.sup.30 doped amorphous semiconductor, of undoped amorphous semiconductor and of metal are deposited on a substrate, whereupon the control elements are formed by masking and etching. The flanks of the control elements are then isolated, whereupon the electrodes and control leads are formed by deposition and etching.
