报告摘要:

Electrostatic discharge (ESD) is one of the most prevalent threats to the reliability of electronic components, circuits, and systems. It is an event in which a finite amount of charge is transferred from one object (i.e., human body) to the other (i.e., microchip). This process can result in a very high current passing through the microchip within a very short period of time, and more than 35% of single-event catastrophic damages can be attributed to such an event. This is a problem with increasing significance in modern and future nanoscale technologies in the context of diminishing device dimensions.

As such, designing robust on-chip ESD structures to protect microchips against ESD stress has been a top priority in the semiconductor industry. The continuing down-sizing of modern CMOS and compound processes makes the ESD-related issues even more prominent, and one can predict with certainty that the availability of effective and robust ESD protection solutions will be a critical factor to the success of the advancement of nano-scale technology. In fact, many semiconductor companies worldwide are having difficulties in meeting the increasingly stringent ESD protection requirements for various electronics applications.

There has been a wide spread use of integrated circuits in consumer applications. An example is the automotive electronics which are typically operated in a voltage range of 40-60 V. This relatively high-voltage operation imposes certain challenges to the design of ESD protection solutions embedded in the modern vehicles. On the other hand, due to the huge market of civil wireless communications, low-voltage integrated circuits are also in high demands. Effective ESD protection solutions for these high-speed circuits are typically required to operate within a very narrow ESD design window and with a minimal loading effect (i.e., high transparency), hence introducing a different set of challenges. Moreover, the continuing scaling of CMOS process toward the 5-nm node makes the design and realization of advanced ESD protection solutions even more demanding and difficult in the coming years.

Meanwhile, the surge protection is also important for the advanced electronic system. various specifications such as the HBM, contact discharge and air discharge related with ESD phenomenon, as well as the clamping voltage and the peak current related with surge phenomenon are required in kinds of chips and electronic system. Robust ESD and surge protection are indispensable for improving the reliability of electronic system.

This seminar will cover the ESD and surge protection fundamentals and concepts, ESD and surge testing and characterizations, and ESD and surge protection designs and optimizations. Various effective ESD protection solutions for low- and high-voltage integrated circuits developed in modern and advanced CMOS and compound technologies, and surge protection solutions for advanced electronic system will be presented and discussed. Moreover, the complete tests of wafer-level, system-level ESD and surge protection will be also introduced. A Q&A session will also be held at the end of the seminar.
