Abstract
In order to improve the holding voltage (Vh) of low-voltage triggering silicon-controlled rectifier (LVTSCR), a cascade-MOS-embedded LVTSCR (MTSCR) and a floating Pwell MTSCR (FPMTSCR) are designed and manufactured based on a 0.18 μm CMOS process. In these two kinds of devices, MTSCR embeds a cascaded PMOS in traditional LVTSCR to form a surface shunting path to improve the holding voltage. FPMTSCR adds a narrow floating Pwell (PW2) in the drain region of the cascaded PMOS of MTSCR to further improve the holding voltage. The TLP and VF-TLP test results indicate that, compared to LVTSCR and MTSCR, FPMTSCR has higher holding voltage (Vh), higher holding current (Ih) and the high CDM robustness, and the low on-state resistance (Ron).
