Advanced Simulation Tools to Fight Microchip Variations

13.11.2012
European Research Consortium to Develop Simulation Tools Minimizing the Impact of Process Variations on Microelectronic Chips

Process, device, and circuit simulation tools are essential in reducing time to market and the cost of new microchip technology development, delivering faster computers, better consumer products and fueling the digital economy.

The International Technology Roadmap for Semiconductors (ITRS) estimates that the use of such tools reduces chip development times and costs by about 40%. Advanced semiconductor devices and circuits are increasingly affected by different kinds of variations which occur during the process of chip fabrication.

Within the European project SUPERTHEME, a tool chain for the simulation of the impact of process variations on the devices, circuits and systems fabricated will be developed. This will allow the global semiconductor industry to minimize the detrimental effects of such variations on chips used e.g. in computers, tablets and mobile phones.

CMOS process variability includes both systematic variations caused by equipment settings and inhomogeneities which cannot be controlled with sufficient accuracy, and statistical variations which are for instance caused by the discreteness of charge and the granularity of matter in nanometer scale transistors. Effects from various sources of process variations, both systematic and stochastic, influence each other and lead to variations of the electrical, thermal and mechanical behavior of devices, interconnects and circuits. This presents a major challenge for the continued scaling of transistor dimensions and the increase in the com-plexity and functionality of computer chips which are essential for the economic success of the semiconductor industry.
Correlations between different effects of variability are of key importance because they drastically affect the production yield and the performance of chips and corresponding consumer products. Whereas the comprehensive experimental investigation of these effects is largely impossible, suitable simulation tools offer the possibility to pre-dict the effect of process variations on subsequent process steps and on the behavior of final fabricated devices and circuits. This important application of simulation is among others high-lighted in the ITRS.

The SUPERTHEME consortium will address and remove the most problematic weaknesses which limit the use of current simulation software to study the influence of both systematic and stochastic process variability and its interaction with electro-thermo-mechanical effects. Particular emphasis will be put on the study of correlations as their treatment needs to be an essential feature of the simulation system. The project will efficiently combine the use of commercially available software and leading-edge background results of the consortium partners with the research, development and implementation of the key missing elements bridging the current critical gap between variability simulation at the process and device/interconnect level. The capabilities of the software system will be demonstrated both on advanced analog circuits and on aggressively scaled digital CMOS technologies.

To reach these ambitious goals, a consortium of European companies active in complementary fields and leading European research institutes and Universities has been formed, which covers a wide range of expertise from semiconductor equipment and technology to modelling and simulation, and finally industrial exploitation.

On October 2, 2012, the project coordinator, the Fraunhofer IISB in Erlangen, Germany, hosted the kickoff meeting for the 3-year project, which has a total budget of 4.79 million Euros.

SUPERTHEME is funded by the European Union in the 7th Framework Programme, under the ICT project number 318458.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
