Abstract
- A novel CMOS-process-compatible high-holding voltage silicon-controlled rectifier (HHV-SCR) for electrostatic discharge (ESD) protection is proposed and demonstrated by simulation and transmission line pulse (TLP) testing. The newly introduced hole (or electron) recombination region H-RR (or E-RR) not only recombines the minority carrier in parasitic PNP (or NPN) transistor base by N+ (or P+) layer, but provides the additional recombination to eliminate the surface avalanche carriers by newly added P+ (or N+) layer in H-RR (or E-RR), which brings about a further improvement of holding voltage (V h). Compared with the measured V h of 1.8 V of low-voltage triggered silicon-controlled rectifier (LVTSCR), the V h of HHV-SCR can be increased to 8.1 V while maintaining a sufficiently high failure current (I t2 > 2.6 A). An improvement of over four times in the figure of merit (FOM) is achieved.
