Abstract:
An ESD cell includes an n+ buried layer (NBL) within a p-epi layer on a substrate. An outer deep trench isolation ring (outer DT ring) includes dielectric sidewalls having a deep n-type diffusion (DEEPN diffusion) ring (DEEPN ring) contacting the dielectric sidewall extending downward to the NBL. The DEEPN ring defines an enclosed p-epi region. A plurality of inner DT structures are within the enclosed p-epi region having dielectric sidewalls and DEEPN diffusions contacting the dielectric sidewalls extending downward from the topside surface to the NBL. The inner DT structures have a sufficiently small spacing with one another so that adjacent DEEPN diffusion regions overlap to form continuous wall of n-type material extending from a first side to a second side of the outer DT ring dividing the enclosed p-epi region into a first and second p-epi region. The first and second p-epi region are connected by the NBL.

Claim (Index 19):
The semiconductor device of  claim 1 , wherein the outer isolation ring forms a shape including four sides, the four sides including the first side and the second side, the first side and the second side being opposite from each other.
