Abstract: A device includes a first region, a second region disposed on the first region, a third region and a fourth region abutting the third region disposed in the second region, a fifth region disposed in the third region and coupled to a collector disposed above, and a sixth region disposed in the fourth region and coupled to an emitter disposed above. A first isolation is disposed between the collector and the emitter. A seventh region is disposed in the fifth region and coupled to the collector is spaced apart from the first isolation. The first region, the third region, the fifth region, the collector and the emitter have a first conductivity type different from a second conductivity type that the second region, the fourth region, the sixth region and the seventh region have.

Abstract: An ESD protection device may be provided, including: a substrate including a first conductivity region and a second conductivity region arranged therein. The first conductivity region may include a first terminal region and a second terminal region electrically coupled with each other. The second conductivity region may include a third terminal region and a fourth terminal region electrically coupled with each other. The second conductivity region may further include a fifth terminal region electrically coupled with the first and second terminal regions. The fifth terminal region may be arranged laterally between the third terminal region and the fourth terminal region. The first conductivity region, the first terminal region, the third terminal region, and the fifth terminal region may have a first conductivity type. The second conductivity region, the second terminal region, and the fourth terminal region may have a second conductivity type different from the first conductivity type.

Abstract: A semiconductor device and method of fabrication for such device in which a P- epitaxial layer is positioned above a P++ substrate. A P++ buried layer implant is positioned within the device between the P++ substrate and the P- epitaxial layer. A connecting p+ implant is placed within the epitaxial layer above the buried p+ blanket layer implant. In one exemplary embodiment, the device includes a shallow P-well with the P+ connecting implant in a position within the epitaxial layer connecting the shallow P-well and the buried P+ blanket implant layer.
