Abstract (en)

[origin: DE19828191C1] A lateral high-voltage transistor has a semiconductor body composed of a weakly doped semiconductor substrate (1) of a first conductivity type, an epitaxial layer (2) of the opposite conductivity type applied to the semiconductor substrate (1), a drain electrode (3), a source electrode (5), a gate electrode (7) and a semiconductor region (4) of the first conductivity type provided below the gate electrode (7) and embedded in the epitaxial layer (2). Rows and lines of trenches (7) are provided in the semiconductor layer (2) between the source electrode (5) and the drain electrode (3), the walls of the trenches (8) being highly doped with a doping substance of the first conductivity type.
