  1. Emerging Research Devices ---International technology roadmap for semiconductors

  2. Challenges in the Microelectronics Industry • Challenges related to logic • To extend the CMOS technology to and beyond 45 nm nodes • Invention and reduction to practice of a new manufacturable information and signal processing technology addressing beyond CMOS applications • Challenges related to memory technologies • Need a new memory technology to combine the best features of volatile and non-volatile memories

  3. Emerging Research Devices • New Devices • Non-classical CMOS • Memory devices • Logic Devices • New Architecture

  4. Emerging Research Devices ----Non-classical CMOS • Advanced MOSFETs • Provide a path to scaling CMOS to the end of Roadmap using new transistor structural designs and new materials • Definitions and classifications • Transport-enhanced FETS: enhance the velocity of the carriers • Ultra-thin Body SOI FETs: a thin transistor body is employed • Source/Drain Engineered FETs: engineering the source/drain • Multiple Gate FETs: • N-Gate (N>2) FETs: use more than two gates to improve electrostatic control • Double-gate FETs: use two isolated gates for low-power and mixed-signal processing

  5. Emerging Research Devices ----Memory devices • Attempt to mimic and improve on the capabilities of present day memory technologies • Definitions and classifications • Phase change memory • Floating body DRAM • Nanofloating gate memory (NFGM) • Single/few electron memory • Insulator resistance change memory • Molecular memory

  6. Emerging Research Devices ----Logic Devices • New technologies based on something other than electronic charge that… extend the scaling of information processing technologies through multiple generations beyond 2019. • Fundamental requirements 1. be able to extend microelectronic orders of magnitude beyond the domain of CMOS and be capable of integration on or with a CMOS platform; 2. be able to provide a means for an energy restorative functional process to sustain steady operation

  7. Emerging Research Devices ----Logic Devices • Resonant tunnel devices • Single-electron transistors • Rapid single flux quantum (RSFQ) • Quantum cellular automata (QCA) • 1D structures • Molecular devices • Spin transistors

  8. Emerging Research Architectures • Fine-Grained parallel implementations in nano-scale cellular arrays • Quantum cellular automata architecture implementations • Cellular nonlinear networks • Defect tolerant architecture implementations • Biologically inspired architecture implementations • Coherent quantum computing

  9. Functional Comparison • In the comparisons of newly emerging technologies: • Few of the new technologies are directly competitive with scaled CMOS • Most are highly complimentary • Heterogeneous integration of the emerging technologies with silicon can expand its overall application space.
