Abstract

Official abstract text for this publication.

A semiconductor device includes a substrate partitioned into a cell region, a peripheral circuit region, and an interface region between the cell region and the peripheral circuit region. A guard ring is provided in the interface region of the substrate and surrounds the cell region. A first gate structure is in the cell region, and a second gate structure is in the peripheral circuit region.

First claim

Opening claim text (preview).

What is claimed is: 1. A semiconductor device comprising: a substrate including a cell region, a peripheral circuit region, and an interface region between the cell region and the peripheral circuit region; a guard ring formed in the interface region of the substrate and surrounding the cell region, wherein the guard ring comprises a portion of the substrate at an upper surface of the substrate and is defined by two adjacent isolation layers at the upper surface of the substrate…
