The present DACEL in 2007 (2)?

• Evaluation of IBM CMOS8 technology for use in the
  radiation harsh environment of S-LHC
• Long-term reliability of irradiated oxides (in
  progress)?

  irradiation through accelerated electrical stress
  with
• Channel Hot Carrier Stress
• Fowler-Nordheim Stress (in progress)?
• Design of dedicated structures (silicon out in
  June 2007)?
• Single Event Gate Rupture
• Goal investigate permanent effects due to
  heavy-ion strikes in ultra-thin gate oxides
• Design of dedicated structures (silicon out in
  June 2007)?

The future DACEL in 2008

• Continue work on accurate device lifetime
  prediction
• Further investigate annealing effects
• Dose rate experiments
• Develop a model to extrapolate from accelerated
  experimental data to operating conditions
• Continue work on long-term reliability of
  irradiated devices
• From single MOSFETs to more complex circuits
• Analyze impact of bias conditions during
  irradiation on subsequent response to electrical
  stress

5
The future DACEL in 2008

• Single Event Effects
• Evaluate Single Event Transient (SET) in
  High-speed logic
• Evaluation of an optimized power distribution
  inside a new CMS Tracker for SLHC
• Study of DC-DC and linear regulators to be
  operated in strong magnetic and radiation fields
