    摘要: A semiconductor device has trenches for defining active regions. After a thin diffusion barrier is deposited in the trenches, some of the trenches are selectively etched to leave different areas in the trench. One of the areas has the diffusion barrier completely removed so that the underlying layer is exposed. Another area has the diffusion barrier remaining. An oxidation step follows so that oxidation occurs at a corner where the diffusion barrier was removed whereas the oxidation is blocked by the diffusion barrier, which functions as a barrier to oxygen. The corners for oxidation are those in which compressive stress is desirable, such as along a portion of the border of a P channel transistor. The corners where the diffusion barrier is left are those in which a compressive stress is undesirable such as the border of an N channel transistor.

    摘要: A method for forming a portion of a semiconductor device structure comprises providing a semiconductor-on-insulator substrate having a semiconductor active layer, an insulation layer, and a semiconductor substrate. A first isolation trench is formed within the semiconductor active layer and a stressor material is deposited on a bottom of the first trench, wherein the stressor material includes a dual-use film. A second isolation trench is formed within the semiconductor active layer, wherein the second isolation trench is absent of the stressor material on a bottom of the second trench. The presence and absence of stressor material in the first and second isolation trenches, respectively, provides differential stress: (i) on one or more of N-type or P-type devices of the semiconductor device structure, (ii) for one or more of width direction or channel direction orientations, and (iii) to customize stress benefits of one or more of a or semiconductor-on-insulator substrate.

    摘要: A transfer apparatus includes a shuttle depending from an overhead support with a pair of arms for receiving and shifting a specimen carrier from one conveyor to a second conveyor of a dual-conveyor track. The shuttle is operable to retain a specimen carrier along either the first or second conveyor and to release a specimen carrier along either the first or second conveyor. Sensors are located to detect the presence of a specimen carrier at each of the retention locations, and to confirm the release of a specimen carrier from the shuttle along each of the conveyors. A drive motor for moving the shuttle between the retention and release positions is electrically connected to a command module with a processor, for receiving instructions as to the position of the shuttle. The sensors are also connected to the processor to transmit detection data to the processor. A queue is positioned upstream of the shuttle and is electrically connected to the processor. The queue includes retractable shafts, sensors and scanners for selectively retaining, detecting and scanning identification data from a specimen carrier on either conveyor upstream of the shuttle, and transmitting the information to the processor.

    摘要: A switched reluctance drive, operating either as a motor or a generator, is controlled in a stable manner in the continuous current mode in the presence of supply voltage or electrical load variation. The use of a current control parameter Ix in addition to the conventional on- and off-angles θon, θoff gives the ability to operate smoothly in the continuous current mode and to transition smoothly between operating modes. Once the phase current reaches a pre-determined level Ix, the phase winding may be placed in a freewheel state, thereby controlling the standing current in the phase winding and/or the output voltage.

    摘要: A drive arrangement for driving a rotary component of a fuel pump comprises a resilient member associated with either a drive shaft or the rotary component and engageable with a surface associated with the other of the drive shaft and rotary component. In use, where a braking force greater than a predetermined level is applied to the rotary component, the member rides out of engagement with the surface permitting relative rotary motion of the drive shaft and rotary component.
