摘要： A voltage clamping circuit that protects integrated circuits having multiple separate power supply voltage terminals from damage when an ESD event causes excessive differential voltages between the multiple separate power supply voltage terminals. The voltage clamping circuit has two subgroups of Darlington connected clamping transistors. The first subgroup of Darlington connected clamping transistors is connected between the first power supply voltage terminal and the second power supply voltage terminal. If the differential voltage exceeds the first clamping voltage level, the first subgroup of Darlington connected clamping transistors turn on and restore the first differential voltage to a level less than the first clamping voltage level. The second subgroup of Darlington connected clamping transistors connected between the second power supply terminal and the first power supply terminal. If the differential voltage exceeds the second clamping voltage level, the second subgroup of Darlington connected transistors turn on and restore the differential voltage to a level less than the second clamping voltage level.

摘要： Circuits, device structures and methods are disclosed which protect CMOS semiconductor devices, having oxides as thin as 32 Angstrom, from electrostatic discharge (ESD) by utilizing a parasitic silicon controlled rectifier (SCR), intrinsic to the semiconductor device. The protection is afforded by providing low voltage triggering of the parasitic SCR in the order of 1.2 Volt. Triggering at such low voltages is made possible by means of a displacement current trigger which causes components of the SCR (parasitic npn and pnp bipolar transistors) to conduct, i.e., to trigger the SCR. The displacement current is realized by a junction capacitance, which is connected on one side to the pad to be protected and on the other side to terminals of the aforementioned parasitic bipolar transistors. Two ways of realizing the junction capacitance are disclosed.

摘要： An electrostatic discharge (ESD) protective circuit for reducing the electron-tunneling phenomena in NMOS devices. Several complementary metal oxide semiconductor (CMOS) devices act as an ESD protective circuit from being destroyed. The CMOS devices are connected to an internal circuit and a power line provide a bias voltage for the devices. The drains of the CMOS devices are connected to a pad to output a driving current. A NMOS device is connected between the internal circuit and the ESD protective circuit for protecting the NMOS devices in the circuit. As an ESD pulse is input into the ESD protective circuit, the NMOS device is then turned on by the pulse. Thus, positive charges on the gate of the NMOS devices in the ESD circuit is conducted into ground. Therefore, the NMOS device between the internal circuit and the ESD circuit can prevent the gate oxide of the NMOS device in the circuit from damage.
