Abstract
A low-voltage triggering silicon-controlled rectifier (LVTSCR), for its high efficiency and low parasitic parameters, has many advantages in ESD protection, especially in ultra-deep sub-micron (UDSM) IC and high frequency applications. In this paper, the impact factors of the snapback characteristics of a LVTSCR and the configuring modes are analyzed and evaluated in detail. These parameters include anode series resistance, gate voltage, structure and size of devices. In addition, a double-trench LVTSCR is presented that can increase the hold-on voltage effectively and offers easy adjustment. Also, its snapback characteristics can obey the ESD design window rule very well. The strategy of ESD protection in a RFIC using a LVTSCR is discussed at the end of the paper.-
