Efficient ESD Verification For 2.5/3D Automotive ICs


Protection against electrostatic discharge (ESD) events is an extremely important aspect of integrated circuit (IC) design and verification, particularly for 2.5/3D designs targeted for automotive systems. ESD events cause severe damage to ICs due to a sudden and unexpected flow of electrical current between two electrically charged objects. This current may be caused by contact, an electrical ... » read more

Research Bits: Nov. 25


3D-printed ESD protection Researchers from Lawrence Livermore National Laboratory developed a printable elastomeric silicone foam for electronics packaging that provides both mechanical and electrostatic discharge (ESD) protection. The team used a 3D printing technique called direct ink writing (DIW), an extrusion process in which a paste with controlled rheological properties such as elast... » read more

Design Optimal ESD Protection With Context-Aware SPICE Simulation


Electrostatic discharge (ESD) is a major reliability concern for modern ICs. Ensuring the robustness of ICs in an ESD event by providing adequate ESD protection is proving to be a major challenge for IC designers due to factors such as shrinking of the design features, reduction in gate oxide thickness, increase in the contact and interconnect resistance and an increase in the overall design co... » read more

What To Do About Electrostatic Discharge


Electrostatic discharge is a well-understood phenomenon, but it’s becoming more difficult to plan for as single chips are replaced by multiple chips or chiplets in a package, and as the density of components continues to increase with each new node. In both cases, the probability for failure increases unless these sudden shocks are addressed in the design. Dermott Lynch, director of product m... » read more

The Ansys Charge Plus PiC Solve


All surfaces are exposed to radiation, whether aircraft fuselages, satellite skins, or solar panels, are subjected to ionization effects through the accumulation of charged plasmas. Such plasmas present critical hazards to these platforms as their sudden nonlinear discharges can damage or destroy surfaces and underlying electronic components. Through the Particle-in-Cell solver, Ansys Charge Pl... » read more

ESD Co-Design For High-Speed SerDeS In FinFET Technologies


An electronic device is susceptible to Electrostatic Discharge (ESD) damage during its entire life cycle, including the phase from the completion of the silicon wafer processing to when the device (die) is assembled in the system. To avoid yield loss due to ESD damage during this early phase, on-chip ESD protection measures are applied to provide a certain degree of ESD robustness. The componen... » read more

Ensuring ESD Protection Verification With Industry-Standard Checks


Electronic design automation (EDA) verification of electrostatic discharge (ESD) protection is a complex task. Different integrated circuit (IC) design companies use different ESD protection approaches, different design flows, and different verification tools. To establish a consistent and comprehensive ESD EDA verification flow, the ESD Association (ESDA) provides recommended ESD compliance ch... » read more

Are You Paying Proper Attention To Your ESD Design Windows?


Electrostatic discharge (ESD) issues in integrated circuit (IC) chip designs have become more critical at advanced semiconductor process nodes, due to shrinking transistor dimensions and oxide layer thickness [1]. There are many ESD design rules and flows that designers check for common ESD issues, such as topological checks for the existence of ESD protection devices, current density (CD) chec... » read more

2.5/3D IC Reliability Verification Has Come A Long Way


2.5D/3D integrated circuits (ICs) have evolved into an innovative solution for many IC design and integration challenges. As shown in figure 1, 2.5D ICs have multiple dies placed side-by-side on a passive silicon interposer. The interposer is placed on a ball grid array (BGA) organic substrate. Micro-bumps attach each die to the interposer, and flip-chip (C4) bumps attach the interposer to the ... » read more

Context-Aware SPICE Simulation Improves The Fidelity Of ESD Analysis


Electrostatic discharge (ESD) is a major reliability concern for integrated circuit (IC) designs. ESD verification is proving to be a significant challenge at advanced nodes, due to growing IC design complexity and transistor counts. Traditional ESD verification approaches using parasitic extraction followed by SPICE simulation are deficient in providing simulation results in a practical runtim... » read more
