Abstract:
1. A silicon control rectifier, comprising: a silicon layer in direct physical contact with a buried oxide layer of a silicon-on-insulator substrate, a top surface of said silicon layer defining a horizontal plane; first, second, third, fourth and fifth doped regions in said silicon layer, said first, second, third, fourth and fifth doped regions having respective first, second, third, fourth and fifth net peak doping concentrations, said third doped region between and abutting said first and said fourth doped regions, said fourth region between and abutting said second and third doped regions, said second and third doped regions not abutting, said first and fourth doped regions not abutting, said fifth doped region abutting only said first doped region, said first and fifth doped regions doped the same dopant type; wherein a path of current flow from said first doped region, through said second doped region, said third doped region and said fourth doped region to said fifth doped region, is in a single horizontal direction parallel to said horizontal plane.
