Abstract
A silicon controlled rectifier (SCR) includes a first p-well region, a second p-well region, and an n-doped region. The first p-well region is coupled to a first trigger terminal via a first p-doped tap region disposed in the first p-well region. The first p-doped tap region has a higher concentration of a p-type dopant than the first p-well region. The second p-well region is coupled to a second trigger terminal via a second p-doped tap region disposed in the second p-well region. The second p-doped tap region has a higher concentration of a p-type dopant than the second p-well region.
