  • 220VAC power converters in UHV technology• Sofics has recently engaged with 2 different customers to define ESD solutions for 220V AC to DC power converters for green technology applications• Sofics offers ESDdoctor consulting for such technology – IC application review to define the ESD protection requirements  Face-to-face meeting(s) and off-site analysis – Process review to determine sensitivity and robustness of devices  May include definition of TEG elements and/or ESD measurements – ESD solution recommendation: strategy – device – implementation  May include layout implementation review – Limited budget project is possible  NRE (service/consulting fee) including travel budget – Solution fee based on performance/commercial releaseSOFICS © 2011 Proprietary & Confidential 5
  • Sofics supported Asian foundry on 700V platform• Foundry platform – 0.5um 5V, 30V, 80V, 700V• Sofics support – Describe appropriate measurement techniques  Provided guidelines for detecting limitations of the devices – Victim circuit analysis  Study sensitivity of the process based on ESD analysis of basic devices  Summary ESD design windows – ESD analysis  Analysis of the measurements on the ESD devices  Selection of best ESD device types for 30V, 80V, 700V – Generic guidelines for ESD protection in (ultra) high voltageSOFICS © 2011 Proprietary & Confidential 6
  • Sofics supported Asian fabless design house• Technology, application – 700V platform, Energy efficient LED lighting• Sofics support – Study of the specific application  Describe appropriate measurements to verify foundry claims  Summarize sensitivity of the process – ESD analysis  Analysis of the foundry measurements on ESD devices  Selection of best ESD device types – Guidelines for ESD protection in ultra high voltage  Support for appropriate use of diodes and limitations to the rectifying approach – Proposed drastic ESD area saving (>50%) opportunitiesSOFICS © 2011 Proprietary & Confidential 7
