Latest Patents
Yunfeng Xi holds 1 patent for his invention titled "Diode string configured with guard ring silicon-controlled rectifier for negative electrostatic discharge protection." This patent describes a diode string designed for semiconductor circuits, which incorporates a guard ring silicon-controlled rectifier (SCR) to provide effective ESD protection. The diode string consists of multiple NPN transistor diode structures that are electrically connected in series between a reference voltage node and an I/O pad. Each diode structure features a P-type retro-well structure, which includes at least one N+ doped region and one P+ doped region. The P+ guard ring is strategically placed to form the SCR with the first diode structure, ensuring that the diode string is triggered during an ESD event, thereby clamping the I/O pad to the reference voltage node and managing the ESD current effectively.
