    摘要: A cascaded diode structure with a deep N-well for effectively reducing the leakage current of the P-type substrate by floating the base of a parasitic transistor in the cascaded diode structure. The cascaded diode structure includes a P-type substrate, a deep N-well formed on the P-type substrate, a plurality of elemental diodes formed on the deep N-well, and a plurality of connecting parts for cascading the elemental diodes. Each elemental diode includes a P-well formed on the deep N-well, a heavily doped P-type region formed on the P-well, and a heavily doped N-type region formed on the P-well.

    摘要: An ESD clamp circuit includes an ESD detecting unit and a discharge circuit with a longitudinal BJT. The longitudinal BJT is formed on a P-type substrate and includes a deep N-well formed on the P-type substrate, a P-well formed on parts of the deep N-well, a N-well formed on the deep N-well surrounding the P-well, a first N+ region formed on parts of the P-well and electrically coupled to a first voltage, a P+ region formed on the P-well surrounding the first N+ region and electrically coupled to a trigger signal, and a second N+ region formed on the N-well and electrically coupled to a second voltage. In the structure of the longitudinal BJT, the leakage current can be decreased, the current gain can be increased, and the dimension of the ESD clamp circuit can be reduced.
