  9. Why Heterostructure Silicon ?March of Technology • MOORE’S LAW : Transistor density on integrated circuits doubles about every two years – Intel co-founder Gordon E. Moore (1965) • Microelectronic silicon computer “chips” have grown from a single transistor in the 1950s to hundreds of millions of transistors per chip on today’s microprocessor and memory devices

  10. March of Technology • Geometric scaling of transistors : Making Moore’s prediction true • 90-nm technology → 65-nm technology → 45-nm technology → 32-nm technology HALT IN MARCH ? • Performance Degradation for smaller gate lengths • Physical limits in scaling

  11. March of TechnologyHeterostructure Engineering • Heterostructure Engineering: Will ensure Moore’s law continues to hold true • Novel solution to enhance device performance by inherently increasing the mobility of the charge carriers by straining the MOSFET channel

  12. Strained-Si Epitaxial Layers 2-D lattice view of Tensile strained-Si film Vegard’s law: aSiGe(x)=aSi(1-x)+aGe(x) x= Ge fraction aSi=5.43 Å & aGe=5.66 Å

What is Technology CAD (TCAD)Rising Technological Complexity Gate insulator •SiO2/HiK •Leakage •Trapping Gate •Work function •Depletion Channel •Mobility Raised S/D •Material •Activation •Diffusion S/D extension •Activation •Junction (USJ) Device Scaling = More Simulation Needed Application: Design, analyze and optimize semiconductor technologies and devices

  15. Compact multi-level technology/ transistor/subsystem TCAD modeling flow

  16. Advanced TCAD Simulation • Process Simulation Updates • Device Simulation Updates • BSIM4 Model Extraction • Process Optimization using process compact model (PCM) • Sensitivity, uncertainty & yield analysis (Yield Management)

  17. TCAD Optimization and Manufacturability TCAD Simulations PCM Generate new data Manufacturing Visual querying & Visual optimization
