摘要：A method and structure for an integrated circuit comprising a substrate of afirst polarity, a merged triple well region of a second polarity and a doped region of thesecond polarity abutting the well region. The doped region is adapted to suppress latch-
up in the integrated circuit. The doped region is placed under semiconductor devices ofthe first polarity and under the well region contact region. Additionally, the structuremay further include a deep trench (DT) structure and trench isolation (TI) structure tofurther improve latchup robustness.
