Device for electrostatic discharge protection

A method for manufacturing a device, comprising:

• providing a first region on a substrate;
• providing a second region on the first region;
• providing a third region and a fourth region in the second region, wherein the third region abuts the fourth region;
• providing a fifth region disposed in the third region;
• providing a sixth region disposed in the fourth region;
• providing a seventh region disposed in the fifth region;
• providing a collector region over and coupled with the fifth region and the seventh region;
• providing an emitter region and a base region over and coupled with the sixth region;
• providing a first isolation region between the collector region and the emitter region, extending across over the fifth region, the third region, the fourth region and the sixth region;
• and
• providing a second isolation region between the emitter region and the base region,
• wherein the seventh region is configured to be spaced apart from the first isolation region;
• and
• wherein the first region, the third region, the fifth region, the collector region and the emitter region have a first conductivity type;
• wherein the second region, the fourth region, the sixth region, the base region and the seventh region have a second conductivity type;
• and wherein the first conductivity type is different from the second conductivity type.
