Abstract:
Disclosed is an ESD protection device, comprising: a semiconductor substrate; a semiconductor buried layer located in the semiconductor substrate; an epitaxial semiconductor layer located on the semiconductor substrate and comprising a first doped region and a second doped region, wherein the semiconductor substrate and the first doped region are of a first doping type, the semiconductor buried layer, the epitaxial semiconductor layer and the second doped region are of a second doping type, the first doping type and the second doping type are opposite to each other, and the first doped region forms a plurality of interfaces with the epitaxial semiconductor layer. The disclosure improves protection performance and maximum current bearing capacity without increasing parasitic capacitance of the ESD protection device.

Claim (Index 5):
The method according to  claim 4 , wherein said annular region is circular, square or rectangular.
