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.

The SeNaTe project is the next in a chain of thematically connected ENIAC JU KET pilot line projects which are associated with 450mm/300mm development for the 12nm and 10nm technology nodes. The main objective is the demonstration of the 7nm IC technology integration in line with the industry needs and the ITRS roadmap on real devices in the Advanced Patterning Center at imec using innovative device architecture and comprising demonstration of a lithographic platform for EUV and immersion technology, advanced process and holistic metrology platforms, new materials and mask infrastructure. A lithography scanner will be developed based on EUV technology to achieve the 7nm module patterning specification. Metrology platforms need to be qualified for N7s 1D, 2D and 3D geometries with the appropriate precision and accuracy. For the 7nm technology modules a large number of new materials will need to be introduced. The introduction of these new materials brings challenges for all involved processes and the related equipment set. Next to new deposition processes also the interaction of the involved materials with subsequent etch, clean and planarization steps will be studied. Major European stakeholders in EUV mask development will collaboratively work together on a number of key remaining EUV mask issues. The first two years of the project will be dedicated to find the best options for patterning, device performance, and integration. In the last year a full N7 integration with electrical measurements will be performed to enable the validation of the 7nm process options for a High Volume Manufacturing. The SeNaTe project relates to the ECSEL work program topic Process technologies More Moore. It addresses and targets as set out in the MASP at the discovery of new Semiconductor Process, Equipment and Materials solutions for advanced CMOS processes that enable the nano-structuring of electronic devices with 7nm resolution in high-volume manufacturing and fast prototyping.
