VERTICAL SEMICONDUCTOR COMPONENT, IN PARTICULAR VERTICAL TRANSISTOR, WITH MINIMIZED SOURCE-DRAIN LEAKAGE CURRENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18402974 titled 'VERTICAL SEMICONDUCTOR COMPONENT, IN PARTICULAR VERTICAL TRANSISTOR, WITH MINIMIZED SOURCE-DRAIN LEAKAGE CURRENTS

The abstract describes a vertical semiconductor component, specifically a vertical transistor, with a vertically lower drain electrode and a semiconductor layer structure above it. The structure includes at least one drift layer and a trench-shaped conduction channel, where the lower end region of the conduction channel connects to the drift layer. A gate electrode is positioned above the conduction channel, which is conductively linked to a source electrode. The conduction channel features a gradation in a vertically extending wall portion, with outer and inner lateral portions connected by a reduced cross-section intermediate portion.

Original Abstract Submitted

A vertical semiconductor component, in particular a vertical transistor. The component has a vertically lower drain electrode and a semiconductor layer structure arranged vertically above the drain electrode, the semiconductor layer structure having at least one drift layer and a trench-shaped conduction channel, wherein a vertically lower end region of the conduction channel adjoins the drift layer, and wherein a gate electrode is formed vertically above the conduction channel and the conduction channel is conductively connected to a source electrode. The conduction channel has, in an at least partially vertically extending wall portion, a gradation, which is delimited by an upper and a lower boundary surface of the conduction channel such that the wall portion has lateral outer and inner portions which are connected to one another via a lateral intermediate portion. The intermediate portion has a reduced cross-section compared with the outer and inner portions.
