Abstract
Provided is a semiconductor device with a diode and a silicon controlled rectifier (SCR) including a substrate having a first conductivity type, a well region having a second conductivity type, a first doped region having the first conductivity type, and a second doped region having the second conductivity type. The well region is disposed in the substrate. The first doped region is disposed in the substrate. The second doped region is disposed in the substrate. The well region and the first doped region form a first PN junction, the well region and the substrate form a second PN junction, and the substrate and the second doped region form a third junction. The first, second, and third PN junctions form the SCR, and the first doped region and the third PN junction form the diode.
