Abstract: 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.

Abstract: A circuit board with a processing unit and a delay line with a controllable number of delay elements fabricated thereon includes apparatus for testing and calibrating the delay line elements. In the test mode, a calibrated pulse is delayed by the delay line while determining the logic state of pulse at two times, the interval between the two times being the same as the pulse width. By adding delay elements, the period of the calibrated pulse as a function of number of delay elements can determine the delay of each delay element. In the calibration mode, the delay line is configured as a ring oscillator and the frequency of the ring oscillator as a function of number of delay elements provides the time delay for the individual elements.

Abstract: In a non-volatile memory unit such as a flash memory unit, the degradation of charge can result in an error during a read operation. By using the error checking and correction techniques, a determination can be made whether a detected error can be corrected and, if correctable, is the consistent with charge degradation at that bit position displaying the error. When a correctable error is detected, the signal group address and the correction pattern are stored and an interrupt request flag applied to the central processing unit. When the interrupt flag is processed, the central processing unit, using the signal group address and the correction pattern, restores the charge of the bit position in the memory unit. In this manner, further read operations involving the restored bit position will not repeat the corrected error.

Abstract: Dopants are implanted at relatively high energies into an unmasked first region of a semiconductor substrate through a thin layer of gate electrode material and a gate dielectric layer. Lower energy dopants are then implanted into the thin layer of gate electrode material. The first region is then masked off, and the process is repeated in a previously masked, but now unmasked, second region of the semiconductor substrate. A second (and usually thicker) layer of gate electrode material is then formed over the thin layer of gate electrode material. The layer of thick gate electrode material, the layer of thin gate electrode material and the layer of gate dielectric material are patterned to form one or more gate structures over the doped regions of the substrate. Source and drain regions are formed in the substrate regions adjacent to the gate structures to establish one or more MOS transistors.
