ELECTROSTATIC DISCHARGE (ESD) PROTECTION ELEMENT AND ESD CIRCUIT THEREOF |
摘要 |
An ESD protection circuit connected between an I/O pad and an internal circuit is disclosed. The ESD protection circuit includes a P type ESD protection element which has a first P type doped region and a first N type doped region. The covered shape of the first P type doped region is circular, and the first N type doped region is disposed to encompass said first P type doped region. During an ESD event, the first P type doped region of the P type ESD protection element receives an ESD current and uniformly drains it away.
