A Review of Super Junction LDMOS

Super Junction Lateral Double-diffused MOSFET (SJ-LDMOS) is one of the important attractive devices in high-voltage integrated circuit and power integrated circuit. However, the SJ-LDMOS is generally implemented on a low-resistance substrate, which always suffers from substrate-assisted depletion (SAD) effect, which thus degrades the performance of devices. A number of literatures have been published to solve the SAD effect and improve performance. This review summarizes the developments made in SJ-LDMOS based on bulk silicon, silicon on insulator, and silicon on sapphire in the last 10 years. Finally, the future work what researchers can do on the SJ-LDMOS also has been proposed.
