In order to seek an electro-static discharge with higher failure current per unit area and latch-up immunity, a novel multi-finger dual-direction silicon controlled rectifier (DDSCR) using the 0.5 μ m complementary and double-diffusion metal-oxide-semiconductor technology was proposed. The working principle of the device is analyzed by using equivalent circuit and technology computer aided design simulation. From the test result of the transmission line pulse testing system we can see that the holding voltages for the traditional dual-direction silicon controlled rectifiers with a single-finger and two-fingers are 11.34 V and 7.63 V, respectively, which is decreased as the number of fingers increases. The holding voltage of the proposed device is 12.2 V, which is higher than that of the traditional 2-finger DDSCR and suitable for communication interface high voltage electrostatic discharge (ESD) protection. Furthermore, the influence of some dimensions, fingers and total f...
