绝缘体上硅(SOI)工艺具有寄生电容小、速度快和抗闩锁等优点,成为低功耗和高性能集成电路(IC)的首选.但SOI工艺IC更易受自加热效应(SHE)的影响,因此静电放电(ESD)防护设计成为一大技术难点.设计了一款基于130 nm部分耗尽型SOI (PD-SOI)工艺的数字专用IC (ASIC).针对SOI工艺ESD防护设计难点,进行了全芯片ESD防护原理分析,通过对ESD防护器件、I/O管脚ESD防护电路、电源钳位电路和ESD防护网络的优化设计,有效减小了SHE的影响.该电路通过了4.5 kV人体模型ESD测试,相比国内外同类电路有较大提高,可以为深亚微米SOI工艺IC ESD防护设计提供参考. 相似文献

ESD protection strategies in advanced CMOS SOI ICs 总被引:1,自引:0,他引:1
This paper represents a part of the ESREF 2007 tutorial on the design of IC protection circuits built with advanced deep sub-micron CMOS silicon-on-insulator (SOI) technologies. The tutorial covers fundamental aspects of active rail clamp Electrostatic Discharge (ESD) protection approach to meet the human body model (HBM), machine model (MM), and charged device model (CDM) requirements in SOI ICs. The paper focuses on 65 nm SOI ESD protection network and design methodology including both device and circuit level characterization data. It compares pulsed measurement results of SOI MOSFETs and diodes to bulk devices. It also introduces a response surface method (RSM) to optimize device sizes in the ESD networks. 相似文献

The electrostatic discharge (ESD) protection capability of SOI CMOS output buffers has been studied with Human Body Model (HBM) stresses. Experimental results show that the ESD voltage sustained by SOI CMOS buffers is only about half the voltage sustained by the bulk NMOS buffers. ESD discharge current in a SOI CMOS buffer is found to be absorbed by the NMOSFET alone. Also, SOI circuits display more serious reliability problem in handling negative ESD discharge current during bi-directional stresses. Most of the methods developed for bulk technology to improve ESD performance have minimal effects on SOI. A new Through Oxide Buffer ESD protection scheme is proposed as an alternative for SOI ESD protection. In order to improve ESD reliability, ESD protection circuitries can be fabricated on the SOI substrate instead of the top silicon thin film, after selectively etching through the buried oxide. This scheme also allows ESD protection strategies developed for bulk technology to be directly transferred to SOI substrate.<> 相似文献

A model for predicting the electrostatic discharge (ESD) protection level of PD-SOI MOSFETs and diodes is presented along with data to support the model. The form of the model is compatible with circuit simulators. An important design rule for layout of multifinger SOI ESD protection MOSFETs has been derived from the model. We present experimental data to support this design rule 相似文献

SCR-based ESD protection in nanometer SOI technologies 总被引:1,自引:0,他引:1

This paper introduces an SCR-based ESD protection design for silicon-on-insulator (SOI) technologies. SCR devices or thyristors, as they are sometimes better known, have long since been used in Bulk CMOS to provide very area efficient, high performance ESD protection for a wide variety of circuit applications. The special physical properties and design of an SOI technology however, renders straightforward implementation of an SCR in such technologies impossible. This paper discusses these difficulties and presents an approach to construct efficient SCR devices in SOI. These devices outperform MOS-based ESD protection devices by about four times, attaining roughly the same performance as diodes. Experimental data from two 65 nm and one 130 nm SOI technologies is presented to support this. 相似文献
