Title: ESD for BCD Process
Post by FuhmW on Dec 7^th, 2006, 4:53am

Dear All

Currently, I'm designing power IC using LDNMOS in BCD process.
Its Vgs is limited to be 5V, and Vds can be very high.
Could anybody tell me where to find materials regarding useful techniques/basic theories
for ESD protection of high voltage pins?

Thank You Very Much

FuhmW,
You will find that there are no universal strategies for protecting HV pins, particularly on a process that is not mainstream CMOS or BiCMOS. There are several options however, and you may need to review a lot of information and theories before you can arrive to a strategy that will meet the needs of your design as well as function in your process.

I would recommend three books to start with:

The general reference thru much of the industry by Duvurry and Amersekera is a great starting point for some one new to ESD design with some good fundamentals and device physics.
http://www.amazon.com/Silicon-Integrated-Circuits-Ajith-Amerasekera/dp/0471498718/sr=1-4/qid=1165846710/ref=sr_1_4/104-6091235-9479939?ie=UTF8&s=books

The next book is newer, by Voldman, but is very detailed in device physics and ESD physics, I would consider this one optional for an individual not dedicated to a lot of ESD design.

http://www.amazon.com/ESD-Circuits-Steven-Howard-Voldman/dp/0470847549/sr=1-3/qid=1165846710/ref=sr_1_3/104-6091235-9479939?ie=UTF8&s=books

Finally, what is probably to most friendly reading to someone new to ESD, this book by Maloney and Dabral is a great introduction to ESD with a well written focus on circuit design techniques and topologies (including HV), but without much of the rich device physics found in the previous two. This is generally a number 1 recommendation to IO designers integrating ESD into their designs.

http://www.amazon.com/Basic-ESD-I-O-Design/dp/0471253596/sr=1-2/qid=1165846710/ref=sr_1_2/104-6091235-9479939?ie=UTF8&s=books

Again however, you may not find exactly what you are looking for in any of these books, as most focus on standard CMOS technologies. (Voldman covers a fair amount of SiGe but that is due to his RF work at IBM).

I hope this helps you find the information you are looking for.
