Abstract
An embedded NMOS triggered silicon controlled rectification device includes a P-type substrate, at least one rectifying zone, and at least one trigger. The rectifying zone includes a first N-type heavily doped area, an N-type well, and a first P-type heavily doped area. Alternatively, the device includes an N-type substrate, a first P-type well, at least one rectifying zone, and at least one trigger. The rectifying zone includes a second P-type well, a first N-type heavily doped area, and a first P-type heavily doped area. The trigger cooperates with the P-type substrate or the first P-type well to form at least one NMOSFET. The trigger is independent to the rectifying zone. The first P-type heavily doped area is arranged between the trigger and the first N-type heavily doped area.
