A noteworthy trade-off between EM, PID, GOI performance, and BEOL defectivity is revealed. On one hand, aggressive NH/sub 3/ pre-treatment process yields improved EM lifetime and PID. On the other hand, the process may provoke Cu hillock and IMD blister defects, as well as GOI yield failure if the treatment is over-aggressive. These disparate observations have been satisfactorily explained using RF plasma-induced heating mechanism in the underlying Cu and IMD. This paper also shows the need to adjust the NH/sub 3/ pretreatment process to meet the overall yield, reliability and manufacturability requirements.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.

Logic product density and performance trends have continued to follow the course predicted by Moore's Law. To support the trends in the future and build logic products approaching one billion or more transistors before the end of the decade, several challenges must be met. These challenges include: 1) maintaining transistor/interconnect feature scaling, 2) the increasing power density dilemma, 3) increasing relative difficulty of 2-D feature resolution and general critical dimension control, 4) identifying cost effective solutions to increasing process and design database complexity, and 5), improving general performance and quality predictability in the face of the growing control, complexity and predictability issues. The trend in transistor scaling can be maintained while addressing the power density issue with new transistor structures, design approaches, and product architectures (e.g. high-k, metal gate, etc.). Items 3 to 5 are the focus of this work and are also strongly inter-related. The general 2-D patterning and resolution control problems will require several solution approaches both through design and technology e.g. reduce design degrees of freedom, use of simpler arrayed structures, improved uniformity, improved tools, etc. The data base complexity/cost problem will require solutions likely to involve use of improved data structure, improved use of hierarchy, and improved software and hardware solutions. Performance assessment, predictability and quality assessment will benefit from solutions to the control and complexity issues noted above. In addition, new design techniques/tools as well as improved process characterization models and methods can address the general performance/quality assessment challenge.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.

Among various design implementation schemes, standard cell ASICs offer the best power efficiency for high-performance applications. The flexibility of ASICs allow for the use of multiple voltages and multiple thresholds to match the performance of critical regions to their timing constraints, and minimize the power everywhere else. We explore the trade-off between multiple supply voltages arid multiple threshold voltages in the optimization of dynamic arid static power. The use of multiple supply voltages presents some unique Physical and electrical challenges. Level shifters need to be introduced between the various voltage regions. The physical layout needs to be designed to ensure the efficient delivery of the correct voltage to various voltage regions. More flexibility can be gained by using appropriate level shifters.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.

Applying the new device models, a novel scale-length based methodology is demonstrated to comprehensively and exhaustively investigate threshold voltage variations in DG MOSFETs. In light of ultra-thin silicon film used as the channel and possible introduction of high-permittivity gate dielectrics, physical, analytical models of quantum mechanical effects, gate direct tunneling current, and fringe-induced barrier lowering effect are developed to assess their impact on DG MOSFET scalability. Scaling limits projections indicate that individual DG MOSFET's with good turn-off behavior are feasible at 10nm scale; however, practical exploitation of these devices toward gigascale integrated systems requires significant improvement in process control.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.
