    摘要: A structure comprises a deep sub-collector buried in a first epitaxial layer and a near sub-collector buried in a second epitaxial layer. The structure further comprises a deep trench isolation structure isolating a region which is substantially above the deep sub-collector, a reach-through structure in contact with the near sub-collector, and a reach-through structure in contact with the deep sub-collector to provide a low-resistance shunt, which prevents COMS latch-up of a device. The method includes forming a merged triple well double epitaxy/double sub-collector structure.

    摘要: A structure comprises a deep subcollector buried in a first region of a dual epitaxial layer and a reachthrough structure in contact with the deep subcollector to provide a low-resistive shunt which prevents CMOS latch-up for a first device. The structure may additionally include a near subcollector formed in a higher region than the deep subcollector and under another device. At least one reachthrough electrically connects the deep subcollector and the near subcollector. The method includes forming a merged triple well double epitaxy/double subcollector.
