ST selects Agilent's 3D simulation software for ESD structures

Agilent Technologies Inc. has announced that STMicroelectronics has chosen Agilent's Electromagnetic Professional (EMPro) software for the development of ESD structures based on advanced CMOS process technology.

As process geometries shrink to 40nm and beyond, energy dissipation capacity from electrostatic discharge (ESD) protection devices is becoming more of a design challenge. ESD designs are process-technology-dependent, and lengthy simulations are typically required to systematically assess key ESD issues.

Therefore, accelerating the design flow is becoming critical for IC development and availability. With its ability to perform fast EM simulations in the time domain, EMPro's Finite Difference Time Domain (FDTD) EM simulator is well suited to monitor the high electrical fields generated by the electric discharge within innovative ESD structures. Running the FDTD simulation on GPU cards accelerates simulation speeds by an order of about 10x.

"Because our customers require more speed and accuracy to tackle their coupled ESD and electromagnetic compatibility challenges, it is critical for us to elaborate and assess solutions that are optimised, reliable and developed in record time to enable their first-run silicon success," said Philippe Galy, expert ESD/Latch-up teams manager, ST. "Meeting these needs is a major initiative for ST, and our collaboration with Agilent has led to successful achievements with solutions and tools that satisfy these objectives."
