Abstract
SCRs are a must for ESD protection in low voltage—high speed I/O as well as ESD protection of RF pads due to least parasitic loading and smallest foot print offered by SCRs. However, conventionally designed SCRs in FinFET and Nanowire technology suffer from very high turn-on and holding voltage. This issue becomes more severe in sub-14 nm non-planar technologies and cannot be handled by conventional approaches like diode- or transient-turn-on techniques. Proposed invention discloses SCR concept for FinFET and Nanowire technology with diffused junction profiles with sub-3V trigger and holding voltage for efficient and robust ESD protection. Besides low trigger and holding voltage, the proposed device offers a 3 times better ESD robustness per unit area.
