The proposed pilot line project WAYTOGO FAST objective is to leverage Europe leadership in Fully Depleted Silicon on Insulator technology (FDSOI) so as to compete in leading edge technology at node 14nm and beyond preparing as well the following node transistor architecture. Europe is at the root of this breakthrough technology in More Moore law. The project aims at establishing a distributed pilot line between 2 companies: - Soitec for the fabrication of advanced engineered substrates (UTBB: Ultra Thin Body and BOx (buried oxide)) without and with strained silicon top film. - STMicroelectronics for the development and industrialization of state of the art FDSOI technology platform at 14nm and beyond with an industry competitive Power-Performance-Area-Cost (PPAC) trade-off. The project represents the first phase of a 2 phase program aiming at establishing a 10nm FDSOI technology for 2018-19. A strong added value network is created across this project to enhance a competitive European value chain on a European breakthrough and prepare next big wave of electronic devices. The consortium gathers a large group of partners: academics/institutes, equipment and substrate providers, semiconductor companies, a foundry, EDA providers, IP providers, fabless design houses, and a system manufacturer. E&M will contribute to the objective of installing a pilot line capable of manufacturing both advanced SOI substrates and FDSOI CMOS integrated circuits at 14nm and beyond. Design houses and electronics system manufacturer will provide demonstrator and enabling IP, to spread the FDSOI technology and establish it as a standard in term of leading edge energy efficient CMOS technology for a wide range of applications battery operated (consumer , healthcare, Internet of things) or not. Close collaboration between the design activities and the technology definition will tailor the PPAC trade-off of the next generation of technology to the applications needs.

In this paper we develop several extensions to semi-classical modeling of low-field mobility, which are necessary to treat planar and non-planar channel geometries on equal footing. We advance the state-of-the-art by generalizing the Prange-Nee model for surface roughness scattering to non-planar geometries, providing a fully numerical treatment of Coulomb scattering, and formulating the Kubo-Greenwood mobility model in a consistent, dimension-independent manner. These extensions allow meaningful comparison of planar and non-planar structures alike, and open the door to evaluating emerging device concepts, such as the FinFET or the junction-less transistor, on physical grounds. © 2015 Elsevier Ltd.

18th International Workshop on Computational Electronics, IWCE 2015 | Year: 2015

A physically-grounded modeling, simulation, and parameter-extraction framework that targets design and engineering of ultra-scaled devices and next-generation channel materials. The framework consists of a fast and accurate Schrdinger-Poisson solver/mobility extractor coupled to a device simulator. It brings physical modeling of semiconductor channels to device design and engineering which until now has been the domain of TCAD tools based on purely empirical models. In this work, we specifically explore the framework components required to model devices based on III/V compound semiconductors. © 2015 IWCE.

A framework for FinFET design studies is presented. Our physics-based modeling approach allows to accurately capture the effects of channel cross-section, orientation and strain as well as contact resistance - for the first time all in one tool. Using this approach as a reference, the predictiveness of empirical TCAD models is extended by re-calibration. Our hierarchical tool chain is embedded in an industry-proven framework equipped with DOE and optimization modules. The capabilities are demonstrated in a simulation study on a recent FinFET technology node. © 2015 IEEE.

In this work, the distribution, execution and performance of TCAD simulations on grid and cloud systems are investigated. A module for distributed computing which can uniformly interface both grid and cloud computing systems has been implemented within GTS Framework. Automated allocation of resources for user jobs on a combined platform has been achieved. Traditional grid-computing systems are compared with cloud-based systems. Strategies for cost-effective allocation of cloud-resources are presented. The performance of a typical TCAD application run on a grid, in the cloud, and a hybrid system combining both are assessed. © 2015 IEEE.

Journal of Computational Electronics | Year: 2013

The Vienna Schrödinger-Poisson (VSP) simulation framework for quantum-electronic engineering applications is presented. It is an extensive software tool that includes models for band structure calculation, self-consistent carrier concentrations including strain, mobility, and transport in transistors and heterostructure devices. The basic physical models are described. Through flexible combination of basic models sophisticated simulation setups for particular problems are feasible. The numerical tools, methods and libraries are presented. A layered software design allows VSP's existing components such as models and solvers to be combined in a multitude of ways, and new components to be added easily. The design principles of the software are explained. Software abstraction is divided into the data, modeling and algebraic level resulting in a flexible physical modeling tool. The simulator's capabilities are demonstrated with real-world simulation examples of tri-gate and nanoscale planar transistors, quantum dots, resonant tunneling diodes, and quantum cascade detectors. © 2013 Springer Science+Business Media New York.

While feature sizes are continuously scaled towards atomic dimensions, industry is increasingly confronted with unexpected physical artefacts to be considered at each new technology node. Among these, process variation and parameter degradation lead to reliability concerns impacting integrated circuit design at all abstraction levels. As variation and degradation may become a limiting factor for future scaled technologies, there has been a tremendous research effort in understanding these artefacts. Versatile tools, allowing consideration of these artefacts and their combined impact during the design of ICs are still in their infancy. Rather than developing yet another design support methodology, we aim to combine and refine existing reliability and variability prediction methodologies at the abstraction layers with highest industrial importance: Register transfer (RT) level - usual design entry, gate level where most design for reliability (DfR) techniques are applied, and transistor level - where final sign-off is made.MoRV will cover the strong relationship between variability and ageing, which are usually treated separately, fostering the idea of treating ageing as a form of time-dependent variability. Combined models from transistor, over gate, to RT level will be characterized directly from silicon measurement and all models will be able to interpret the same characterization data base from the silicon measurement.The results will be introduced into a reference design flow combined with a multi-level multi-physics engine. Final goal of MoRV is to enable automated synthesis from specification to circuit. Each model layer will offer reliability and variation prediction for typical and worst case scenarios in order to assess the effectiveness of available design techniques.

Technical Digest - International Electron Devices Meeting, IEDM | Year: 2013

We conduct a comprehensive simulation study of non-planar n-type channels based on consistent, physical models containing measurable quantities rather than fit-parameters. This contrasts empirical thin-body models used in classical/quantum-corrected TCAD. The method involves the self-consistent solution of the two-dimensional Schrödinger-Poisson system, combined with linearized Boltzmann transport in the third dimension. We advance the art of simulation by (i) introducing quantum simulation on unstructured meshes for arbitrary geometries, (ii) providing an efficient framework for rapid evaluation of device designs, and (iii) contributing a surface roughness scattering model for arbitrarily shaped surfaces. Consistent modeling allows us to make reliable assertions with respect to device performance. © 2013 IEEE.
