Abstract
A semiconductor component includes gate structures extending into a silicon carbide body from a first surface. A width of the gate structures along a first horizontal direction parallel to the first surface is less than a vertical extent of the gate structures perpendicular to the first surface. Contact structures extend into the silicon carbide body from the first surface. The gate structures and the contact structures alternate along the first horizontal direction. Shielding regions in the silicon carbide body adjoin a bottom of the contact structures and are spaced apart from the gate structures along the first horizontal direction. Corresponding methods for producing the semiconductor component are also described.
