Abstract

Official abstract text for this publication.

The invention provides a semiconductor structure and a semiconductor device having such semiconductor structure. The semiconductor structure includes: a substrate; a first well having a first conductivity type, which is provided on the substrate; a second well having a second conductivity type and contacting the first well at a boundary in between in a lateral direction; and a plurality of mitigation regions having the first conductivity type or the second conductivity type, provided in the first well and being close to the boundary in a lateral direction and penetrating the first well in a vertical direction.

First claim

Opening claim text (preview).

What is claimed is: 1. A semiconductor structure, comprising: a substrate; a first well having a first conductivity type, provided on the substrate; a second well having a second conductivity type and contacting the first well at a boundary in between in a lateral direction, the second conductivity type being opposite to the first conductivity type; and a plurality of first mitigation regions having the first conductivity type with a doping concentration lower than a doping…
