CKC & Partners Co., Ltd.
Diode, diode string circuit, and electrostatic discharge protection device having doped region and well isolated from each other
A diode includes a substrate, a first insulating layer, a second insulating layer, a well, a deep doped region, a first doped region, and a second doped region. The first insulating layer is disposed on the substrate. The second insulating layer is disposed on the substrate, and defines a cell region with the first insulating layer. The well is disposed on the substrate and beneath the cell region. The deep doped region is disposed in the well and beneath the cell region. The first doped region is disposed in the cell region and on the deep doped region. The second doped region is disposed adjacent to the first doped region. The second doped region is disposed on the deep doped region, and is electrically isolated from the well through the deep doped region and the first doped region.
