Notes

  1. This is a general overview for Renesas QML, Class V, Class Q, and Class T. For part-specific flow details, please contact the local Renesas sales office or representative in your area.
  2. Product that does not meet step coverage requirements per MIL-STD-883, Method 2018 will be evaluated for minimum Metal Thickness requirements using the following criteria:
    • Current Density of 2E5 A/CM2
    • Electromigration rules for the applicable technology
    • A minimum thickness of 2000A for mechanical integrity
    • The thickest metal requirement calculated to meet the appropriate metal thickness will be used as the acceptance criteria for step coverage.
  3. Class V test method 5007 plus PM Electrical Samples, Class Q uses PM Electrical Samples only.
