    摘要： An integrated semiconductor structure that has first and second bipolar transistor structures. The first bipolar transistor structure has a doped tank region in contact with a doped tank region located underneath a contacting sinker. The second bipolar transistor structure has a doped buried region that is the same dopant type as its doped tank region. A method for fabricating an integrated semiconductor structure in a bulk semiconductor wafer. A first patterned photomask is used to form a doped buried region and a doped tank region within the first bipolar transistor structure. A second patterned photomask is used to form a doped buried region and a doped tank region within the second bipolar transistor, plus a doped buried region and a doped tank region underneath a contacting sinker adjacent to the first bipolar transistor.

    摘要： An integrated BiCMOS semiconductor circuit has active moat areas in silicon. The active moat areas include electrically active components of the semiconductor circuit, which comprise active window structures for base and/or emitter windows. The integrated BiCMOS semiconductor circuit has zones where silicon is left to form dummy moat areas which do not include electrically active components, and has isolation trenches to separate the active moat areas from each other and from the dummy moat areas. The dummy moat areas comprise dummy window structures having geometrical dimensions and shapes similar to those of the active window structures for the base and/or emitter windows.
