A PNPN nanoscale diode is formed on a silicon-on-insulator (SOI) wafer and is composed of a serial PNPN chain layer with a nanoscale current channel area. The bottom electrode of the ferroelectric capacitor (FeCAP) is connected to a serial PNPN-nanoscale-diode chain, and the top electrode of FeCAP is connected to the wordline (WL). The bitline (BL) under the FeCAP is also connected to the serial PNPN-nanoscale-diode chain. The serial PNPN-nanoscale-diode chain layers of each nanoscale channel are separated by a dielectric insulator layer. The MEDICI-simulated PNPN-diode snap-back voltage properties are controlled by various process conditions. The leakage current shape of the reverse biased-PN diode is similar to the forward-biased current shape before the snap-back voltage region of the PNPN nanoscale diode.
