Integrated circuit having lateral compensation component

摘要

An integrated circuit and component is disclosed. In one embodiment, the component is a compensation component, configuring the compensation regions in the drift zone in V-shaped fashion in order to achieve a convergence of the space charge zones from the upper to the lower end of the compensation regions is disclosed.

主权项

1. A lateral component comprising:
a semiconductor body having a main surface; a body zone in the semiconductor body, the body zone extending between at least one first electrode for a first zone of a first conductivity type and a second electrode—for a second zone arranged at a distance from the first electrode, the body zone adjoining the first electrode and being—of a second conductivity type, which is opposite to the first conductivity type; a drift zone of the first conductivity type lying between the body zone and the second zone below the main surface and being weakly doped in comparison with the first and the second zones; at least one compensation region of the second conductivity type in the drift zone having a tapering cross-sectional area in the direction toward the second electrode and being situated in a manner adjoining the body zone, wherein the at least one compensation region extends in the drift zone proceeding from the body zone of the second conductivity type toward the second zone only to an extent such that a pedestal region of the drift zone remains between the end of the at least one compensation region and the second zone, the pedestal region adjoining the second zone; and further comprising a planar gate electrode above the body zone and above the main surface.
