Gate-grounded NMOS (GGNMOS) devices with different device dimensions and layout floorplans have been designed and fabricated in 0.13-μm silicide CMOS technology. The snapback characteristics of these GGN-MOS devices are measured using the transmission line pulsing (TLP) measurement technique. The relationships between snapback parameters and layout parameters are shown and analyzed. A TCAD device simulator is used to explain these relationships. From these results, the circuit designer can predict the behavior of the GGNMOS devices under high ESD current stress, and design area-efficient ESD protection circuits to sustain the required ESD level. Optimized layout rules for ESD protection in 0.13-μm silicide CMOS technology are also presented. 相似文献

本文中,在 0.13微米硅化物 CMOS工艺下, 设计了不同版图尺寸和不同版图布局的栅极接地 NMOS器件。TLP测量技术用来获得器件的骤回特性。 文章分析了器件版图参数和器件骤回特性之间的关系。TCAD器件仿真软件被用来解释证明这些结论.通过这些结论,电路设计者可以预估栅极接地NMOS器件在ESD大电流情况下的特性,由此在有限的版图面积下设计符合 ESD保护要求的栅极接地 NMOS器件。本文同时给出了优化后的 0.13微米硅化物工艺下 ESD版图规则。 相似文献
