Among the physical limitations which challenge progress in nanoelectronics for aggressively scaled More Moore, Beyond CMOS and advanced More-than-Moore applications, process variability and the interactions between and with electrical, thermal and mechanical effects are getting more and more critical. 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. Correlations are of key importance because they drastically affect the percentage of products which meet the specifications. Whereas the comprehensive experimental investigation of these effects is largely impossible, modelling and simulation (TCAD) offers the unique possibility to predefine process variations and trace their effects on subsequent process steps and on devices and circuits fab-ricated, just by changing the corresponding input data. This important requirement for and capability of simulation is among others highlighted in the International Technology Roadmap for Semiconductors ITRS. A project partner has also demonstrated how correlations can be simulated.\nWithin SUPERTHEME, the most important weaknesses which limit the use of current TCAD software to study the influence of both systematic and stochastic process variability and its interaction with electro-thermal-mechanical effects will be removed, and the study of correlations will be enabled. The project will efficiently combine the use of commercially available software and leading-edge background results of the consortium with the implementation of the key missing elements and links. It will bridge the current critical gap between variability simulation on process and device/interconnect level, and include the treatment of correlations. The capabilities of the software system will be demonstrated both on advanced analog circuits and on aggressively scaled transistors.

Silicon carbide presents a high breakdown field (2-4 MV/cm) and a high energy band gap (2.33.2 eV), largely higher than for silicon. Within this frame, the cubic polytype of SiC (3C-SiC) is the only one that can be grown on a host substrate with the huge opportunity to grow only the silicon carbide thickness required for the targeted application. The possible growth on silicon substrate has remained for long period a real advantage in terms of scalability regarding the reduced diameter of hexagonal SiC wafer commercially available. Even the relatively narrow band-gap of 3C-SiC (2.3eV), which is often regarded as detrimental in comparison with other polytypes, can in fact be an advantage. The lowering of the conduction band minimum brings about a reduced density of states at the SiO2/3C-SiC interface and MOSFET on 3C-SiC has demonstrated the highest channel mobility of above 300 cm2/(Vxs) ever achieved on SiC crystals, prompting a remarkable reduction in the power consumption of these power switching devices. The electrical activity of extended defects in 3C SiC is a major concern for electronic device functioning. To achieve viable commercial yields the mechanisms of defects must be understood and methods for their reduction developed.. In this project new approaches for the reduction of defects will be used, working on new compliance substrates that can help to reduce the stress and the defect density at the same time. This growth process will be driven by numerical simulations of the growth and simulations of the stress reduction. The structure of the final devices will be simulated using the appropriated numerical tools where new numerical model will be introduced to take into account the properties of the new material. Thanks to these simulations tools and the new material with low defect density, several devices that can work at high power and with low power consumption will be realized inside the project.

The key to the efficient transmission and conversion of low-carbon electrical energy is the improvement of power electronic devices. Diamond is considered to be the ultimate wide bandgap semiconductor material for applications in high power electronics due to its exceptional thermal and electronic properties. Two recent developments - the emergence of commercially available electronic grade single crystals and a scientific breakthrough in creating a MOS channel in diamond technology, have now opened new opportunities for the fabrication and commercialisation of diamond power transistors. These will result in substantial improvements in the performance of power electronic systems by offering higher blocking voltages, improved efficiency and reliability, as well as reduced thermal requirements thus opening the door to more efficient green electronic systems. These improvements are expected to increase the efficiency of power converters by a factor of 4, yielding a 75% reduction in losses. In this context, the objective of GreenDiamond is to fabricate a 10kV transistor in a high power package, followed by a high voltage AC/DC converter based on such devices. To meet GreenDiamonds challenging goals, the consortium gathers experts on power device design, diamond growth and characterization, packaging and testing as well as an innovative end-user. Most of the partners are also involved in SiC or GaN technology, allowing the project to benefit from their ample experience and achievements in wide bandgap semiconductors. As far as diamond transistor structure is concerned, unlike GaN and SiC, Europe still has a significant scientific and technological advantage over non-EU competitors. It is therefore extremely important to maintain the competitive edge that will lead the development of truly green electronics in the near to medium term future.
