| 摘要 |
A mesa-type bidirectional vertical power component, including a substrate of a first conductivity type; a layer of the second conductivity type on each side of the substrate; first regions of the first conductivity type in each of the layers of the second conductivity type; and, at the periphery of each of its surfaces, two successive grooves, the internal groove crossing the layers of the second conductivity type, second doped regions of the first conductivity type being formed under the surface of the external grooves and having the same doping profile as the first regions.
