摘要： An electrostatic discharge protection device coupled between a first power line and a second power line is provided. A first N-type doped region is formed in a P-type well. A first P-type doped region is formed in the first N-type doped region. A second P-type doped region includes a first portion and a second portion. The first portion of the second P-type doped region is formed in the first N-type doped region. The second portion of the second P-type doped region is formed outside of the first N-type doped region. A second N-type doped region is formed in the first portion of the second P-type doped region. The first P-type doped region, the first N-type doped region, the second P-type doped region and the second N-type doped region constitute an insulated gate bipolar transistor (IGBT).

摘要： An ESD protection structure is disclosed. A substrate comprises a first conductive type. A first diffusion region is formed in the substrate. A first doped region is formed in the first diffusion region. A second doped region is formed in the first diffusion region. A third doped region is formed in the substrate. A first isolation region is formed in the substrate, covers a portion of the first diffusion region and is located between the second and the third doped regions. A fourth doped region is formed in the substrate. When the first doped region is coupled to a first power line and the third and the fourth doped regions are coupled to a second power line, an ESD current can be released to the second power line from the first power line. During the release of the ESD current, the second doped region is not electrically connected to the first power line.
