Characterization analysis of UDSM LVTSCR under TLP stress

【摘要】 <正>The characteristics of a low-voltage triggering silicon-controlled rectifier(LVTSCR) under a transmission line pulse(TLP) and the characteristics of high frequency are analyzed.The research results show that the anode series resistance has a significant effect on the key points of the snapback curve.The device characteristics can fit the requirements of a electrostatic discharge(ESD) design window by adjusting the anode series resistance. Furthermore,the set-up time of the ESD has an influence on the turn-on voltage of the LVTSCR.A steep rising edge will cause the turn-on voltage to increase.The parasitic capacitance of the device for different voltage biases and frequencies determines the capacitive impedance,and its accuracy calculation is very important to the ESD design of high frequency circuits.Our research results provide a theoretical basis for the design of an ultra-deep sub-micron(UDSM) LVTSCR structure under ESD stress and the improvement of TLP test technology.更多还原
