    摘要: A method or process is provided for making a semiconductor structure which includes the steps of forming in a semiconductor body a P/N junction and an opening in an insulating layer disposed on the surface of the semiconductor body. A trench is then formed in the semiconductor layer having a sidewall located along a given plane through the opening and through the P/N junction. An insulating material is disposed within the trench and over the insulating layer and a block or segment of material is located over the trench so as to extend a given distance from the trench over the upper surface of the body. The insulating material and the block are then etched so as to remove the block and the insulating material located along the sides of the block. A layer of low viscosity material is formed over the semiconductor body so as to cover the remaining portion of the insulating material, the layer of low viscosity material and the insulating material having similar etch rates. The layer of low viscosity material and the insulating material are then simultaneously etched directionally until all of the layer of low viscosity material is removed. Metallic contacts may now be formed on the surface of the semiconductor body without the concern that the metallic material will seep or enter into the trench causing a short at the P/N junction.

    摘要: The disclosure herein pertains to fashioning an n channel junction field effect transistor (NJFET) and/or a p channel junction field effect transistor (PJFET) with an open drain, where the open drain allows the transistors to operate at higher voltages before experiencing gate leakage current. The open drain allows the voltage to be increased several fold without increasing the size of the transistors. Opening the drain essentially spreads equipotential lines of respective electric fields developed at the drains of the devices so that the local electric fields, and hence the impact ionization rates are reduced to redirect current below the surface of the transistors.

    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.
