Abstract:
A semiconductor component, comprising:a semiconductor substrate of a first conductivity type;a first doped region of a second conductivity type formed in said semiconductor substrate, said first doped region having a surface and an edge region;a second doped region of the second conductivity type formed in said semiconductor substrate;a channel region disposed in said semiconductor substrate between said first and second doped regions;a tunnel dielectric partially covering said surface of said first doped region, said tunnel dielectric having a given thickness;a gate dielectric covering a surface of said channel region and said edge region of said first doped region, said gate dielectric having a thickness substantially equal to said given thickness;a tunnel gate electrode having a surface disposed on said tunnel dielectric;a channel gate electrode having a surface disposed on said gate dielectric; andan insulation structure made of a dielectric material separating said tunnel gate electrode and said channel gate electrode at least at said surface facing said tunnel dielectric and said gate dielectric, respectively.
