ELECTROSTATIC DISCHARGE PROTECTION APPARATUS

The electrostatic discharge (ESD) protection apparatus includes a first well, a second well, a first doping region, and a second doping region. The first well is disposed in a substrate having a firstconductivity type, wherein the first well has a second conductivity type and the substrate is electrically connected to a first pad. The second well is disposed in the first well, wherein the secondwell has the first conductivity type. The first doping region is disposed in the second well, wherein the first doping region has the second conductivity type, and the first doping region is electrically connected to a second pad. The second doping region is disposed in the second well, wherein the second doping region has the first conductivity type. 本发明公开一种静电放电防护装置，其包括第一阱、第二阱、第一掺杂区以及第二掺杂区。第一阱被配置于具有第一导电型的基底中，其中第一阱具有第二导电型，以及基底电连接至第一焊垫。第二阱被配置于第一阱中，其中第二阱具有第一导电型。第一掺杂区被配置于该第二阱中，其中第一掺杂区具有第二导电型，以及第一掺杂区电连接至第二焊垫。第二掺杂区被配置于第二阱中，其中第二掺杂区具有第一导电型。
