    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.

    摘要: In a method of fabricating complementary bipolar transistors with SiGe base regions the base regions of the NPN and PNP transistors are formed one after the other over two collector regions 20, 14 by epitaxial deposition of crystalline silicon-germanium layers 32a, 36a. With this method the germanium profile of the SiGe layers can be freely selected for both NPN and PNP transistors in thus enabling complementary transistor performance to be optimized individually. The SiGe layers 32a, 36a can be doped with an n-type or p-type dopant during or after deposition of the silicon-germanium layers 32a, 36a.
