Abstract: A semiconductor wafer (31) having an impurity diffusion layer formed in an inner surface of a trench (33) is cleaned. The semiconductor wafer (31) is inserted into a furnace, and NH 3  gas is introduced into the furnace in the low-pressure condition to create an atmosphere in which the temperature is set at 800 °C to 1200°C and the partial pressures of H 2 0 and 0 2  are set at 1 x 10- 4  Torr or less. A natural oxide film formed on the inner surface of the trench (33) is removed, and substantially at the same time, a thermal nitride film (35) is formed on the impurity diffusion layer. Then, a CVD silicon nitride film (36) is formed on the thermal nitride film without exposing the thermal nitride film to the outside air in the same furnace. Next, a silicon oxide film (37) is formed on the CVD nitride film. As a result, a composite insulative film formed of the thermal nitride film, CVD silicon nitride film and silicon oxide film is obtained. Then, an electrode (39) for the composite insulative film is formed in the trench.

Abstract: An interconnect structure and method is described herein. First, interconnect lines 14a-d are formed on a semiconductor body 10. Then, a dielectric layer 20 is coated over the semiconductor body and the interconnect lines 14a-d to a thickness sufficient to more than fill the gaps between adjacent interconnect lines. The dielectric layer 20 is baked and then cured at a elevated temperature greater than the baking temperature. By using baking, then curing, the dielectric layer 20 inside the gaps has a lower density than that above interconnect lines and that in open fields. The removal of dielectric layer from the top of the interconnect lines by etchback is optional. Finally, a layer of silicon dioxide 12 is deposited over the interconnect lines 14a-d and the dielectric layer 20. In one embodiment, contact vias 11 are then etched through the silicon dioxide 12 and dielectric layer 20 to the interconnect lines 14a-c. Preferably, the dielectric material is spun on. One advantage of the invention is providing a metallization scheme that reduces line-to-line capacitance. A further advantage of the invention is providing a metallization scheme that reduces crosstalk and power dissipation. A further advantage of the invention is providing a dielectric layer between interconnect lines having a lower density and a lower dielectric constant than dense silicon dioxide.

Abstract: On the example of a three-phase machine having 36 poles, the stator is divided into three 120-deg. segments with one slot for each pole and phase. The actual distribution of slots departs slightly from the regular pattern of 36 slots per segment so that the end teeth can be broader and the length of the segment utilised in full. The induced voltage is phase-shifted from pole to pole for a good sinusoidal waveform.

Abstract: A vascular or endoluminal stent adapted for deployment in a vessel or tract of a patient to maintain an open lumen therein is formed from a metal open-ended tube which is the single component of the stent. The tube has a multiplicity of holes cut by laser through its wall. The through-holes are encompassed by serpentines that constitute the wall, the serpentines extending sinusoidally each in multiple 360° wavelengths in a single turn about the axis of the tube and juxtaposed in plural substantially identical segments disposed with regularity along the axis. Each segment has a length equal to the distance between crests and troughs of the sinusoid. Adjacent serpentines are joined together at crest and trough, respectively, so that their interconnections are 180° out of phase relative to their wavelength. The serpentines and interconnections thereof are shaped throughout for optimum uniform expansion of the stent during deployment thereof, including a notch substantially symmetrically located at either side of the junction of the respective crest and trough of the interconnections between adjacent serpentines. The serpentines are substantially devoid of sharp corners and edges, except at the notches, and each serpentine has an oval cross-section. The regularity of the segments is interrupted at least once along the axis of the tube by serpentines oriented differently from the others, used to maintain the tube's length substantially invariant despite radial expansion of the stent during deployment. The serpentines are pre-stressed and annealed before deployment of the stent to ease deployment and enhance symmetrical radial expansion. The exterior surface of the tube is longitudinally tapered from its mid-point toward its ends, and substantially rounded surfaces prevail throughout the tube.

Abstract: An on-chip cache memory is used to provide a high speed access mechanism to frequently used channel state information for operation of a DMA device that supports multiple virtual channels in a high speed network interface. When an access to a particular channel state is performed, e.g., by a host processor or the DMA device, the cache is first accessed and if the state information is not located currently in the cache, external memory is read and the state information is written to the cache. As the cache does not store all the states stored in external memory, replacement algorithms are utilize to determine which channel state information to remove from the cache in order to provide room to store a recently accessed channel. A doubly linked list is used to track the most recently used channel. As cached channel information is accessed, the corresponding entry is moved to the top of the list. The doubly linked list provides a rapid apparatus and method for updating pointers to the cache. Top and bottom pointers are maintained, pointing to the most recently used and least recently used channels. When a channel is used, it moved to the top of the list. When channel data is moved from external memory to the cache, the bottom pointer points to the channel data to be removed from the cache.

Abstract: In a two-channel magnetic metal detector (32) for a forage harvester (10), positive and negative adaptive detection thresholds (71, 73) are varied according to long term changes in the noise component induced in detection coils (40, 42) by moving ferrous parts of the crop feed mechanism. The adaptive detection thresholds (71, 73) are set at levels determined by the positive and negative peak averages of the noise components in the channels (CH0, CH1) while the crop feed mechanism (18, 20-22) is running at normal speed. Start-up transient noise induced in the detection coils (40, 42) as the crop feed mechanism accelerates may exceed the adaptive thresholds (71, 73) as thus set, thereby triggering false indications that a tramp metal object has been detected in the crop feed path. At start-up of the crop feed mechanism, the detection thresholds are raised to prevent false indications. An increase in a channel noise signal is taken as an indication that the crop feed mechanism (18, 20-22) is accelerating. The detection thresholds are then raised to a level (79, 81) above any transient noise level expected during acceleration of the crop feed mechanism. After a predetermined time (T1-T2) sufficient for the feed mechanism to reach normal operating speed, the detection thresholds are set at their adaptive detection levels (71, 73).

Abstract: A method of operating a nonvolatile ferroelectric memory cell including a polarized ferroelectric capacitor includes the steps of reading and restoring a first polarization state of the ferroelectric capacitor at a voltage not sufficient to fully saturate the ferroelectric capacitor, but sufficient to release a detectable amount of charge corresponding to the first polarization state. Writing a second polarization state in the ferroelectric capacitor is performed at a voltage sufficient to fully saturate the ferroelectric capacitor. During a read and restore operation, the plate line of the memory cell is pulsed with first and second voltage pulses that each have a voltage magnitude less than the normal five volt logic pulse, for example four volts. During a write operation, the plate line of the memory cell is pulsed with a voltage that has a magnitude greater than the normal five volt logic pulse, for example six to seven volts.
