  • Patent number: 8609501
    Abstract: A method of fabricating an integrated circuit including bipolar transistors that reduces the effects of transistor performance degradation and transistor mismatch caused by charging during plasma etch, and the integrated circuit so formed. A fluorine implant is performed at those locations at which isolation dielectric structures between base and emitter are to be formed, prior to formation of the isolation dielectric. The isolation dielectric structures may be formed by either shallow trench isolation, in which the fluorine implant is performed after trench etch, or LOCOS oxidation, in which the fluorine implant is performed prior to thermal oxidation. The fluorine implant may be normal to the device surface or at an angle from the normal. Completion of the integrated circuit is then carried out, including the use of relatively thick copper metallization requiring plasma etch.

  • Patent number: 7968878
    Abstract: A serpentine double gated diode array for monitoring stress induced defects is disclosed. The diode array is configured with adjacent gate segments and gate loops in close proximity to active areas to maximize a sensitivity to stress induced defects. The diode array is compatible with conventional electrical testing. Scanning capacitance microscopy (SCM) and scanning spreading resistance microscopy (SSRM) may be used to isolate individual stress induced defects. Variations in the gate configuration allow estimation of effects of circuit layout on formation of stress induced defects.

  • Patent number: 5346851
    Abstract: A quantum effect device implementation of the Shannon Decomposition Function in the form of a Shannon Cell is provided in which a first quantum dot logic unit (50) is coupled between the X input and the output of the Shannon Cell. A second quantum dot logic unit (52) is coupled between the Y input and the output of the Shannon Cell. The control input to the Shannon Cell is coupled to both the first and second quantum dot logic units (50 and 52) such that current flows through the appropriate quantum dot logic unit (50 or 52) depending upon the logic state of the control input.
