    摘要: A Semiconductor component having a space saving edge structure is disclosed. One embodiment provides a first side, a second side, an inner region, an edge region adjoining the inner region in a lateral direction of the semiconductor body, and a first semiconductor layer extending across the inner region and the edge region and having a basic doping of a first conductivity type. At least one active component zone of a second conductivity type, which is complementary to the first conductivity type, is disposed in the inner region in the first semiconductor layer. An edge structure is disposed in the edge region and includes at least one trench extending from the first side into the semiconductor body. An edge electrode is disposed in the trench, a dielectric layer is disposed in the trench between the edge electrode and the semiconductor body, a first edge zone of the second conductivity type adjoin the trench and are at least partially disposed below the trench.

    摘要: An integrated memory transistor and a memory unit including a plurality of integrated memory transistors is disclosed. Generally, the integrated memory transistor includes an electron source, a channel region, a control region, a charge storage region, a source-side pocket doping region, and a drain-side pocket doping region. The electron source is operable to transport electrons to the channel region when the integrated memory transistor operates in a read mode. Further, the electron source includes a drain terminal region and a source terminal region. The channel region is arranged between the drain terminal region and source terminal region. The charge storage region is arranged between the control region and the channel region. The source-side doping region is arranged nearer to the source terminal region than to the drain terminal region. The drain-side pocket doping region is arranged asymmetrical to the source-side pocket doping region.
