Abstract
In an example, a device includes a semiconductor substrate having a top surface. The device also includes a P-doped well formed in the semiconductor substrate and extending downwardly from the top surface. The device includes a cathode of a diode formed by an N-doped region in the P-doped well. The device also includes an anode of the diode formed by a P-doped region, the P-doped region spaced away from the N-doped region in the P-doped well. The device includes a deep N-type buried layer (DNBL) formed in the semiconductor substrate, the P-doped well formed between the top surface and the DNBL. The device also includes an N-doped well extending from the top surface to the DNBL.
