    摘要: A method, apparatus, and stored instructions are provided for transforming a query representation by unnesting a predicate condition that is based on whether or not a result exists for a subquery of the predicate condition. An initial query representation is received. The initial query representation represents an initial query that includes an EXISTS-equivalent predicate or a NOT-EXISTS-equivalent predicate and at least one other predicate in a disjunction. The initial query representation is transformed into a semantically equivalent transformed query representation that represents a transformed query. The transformed query includes, instead of the EXISTS-equivalent predicate or a NOT-EXISTS-equivalent predicate, a join operator that references the data object. The transformed query representation, when used for execution, causes the at least one other predicate to be applied separately from a join operation caused by the join operator such that execution of the initial representation is semantically equivalent to execution of the transformed representation.

    摘要: A method for fabricating a high-density array of crown capacitors with increased capacitance while reducing process damage to the bottom electrodes is achieved. The process is particularly useful for crown capacitors for future DRAM circuits with minimum feature sizes of 0.18 micrometer or less. A conformal conducting layer is deposited over trenches in an interlevel dielectric (ILD) layer, and is polished back to form capacitor bottom electrodes. A novel photoresist mask and etching are then used to pattern the ILD layer to provide a protective interlevel dielectric structure between capacitors. The protective structures prevent damage to the bottom electrodes during subsequent processing. The etching also exposes portions of the outer surface of bottom electrodes for increased capacitance (>50%). In a first embodiment the ILD structure is formed between pairs of adjacent bottom electrodes, and in a second embodiment the ILD structure is formed between four adjacent bottom electrodes.

    摘要: A strained-channel semiconductor structure and method of fabricating the same. The strained-channel semiconductor structure comprises a substrate composed of a first semiconductor material with a first natural lattice constant. A channel region is disposed in the substrate and a gate stack is disposed over the strained channel region A pair of source/drain regions are oppositely disposed in the substrate adjacent to the channel region, wherein each of the source/drain regions comprises a lattice-mismatched zone comprising a second semiconductor material with a second natural lattice constant rather than the first natural lattice constant, an inner side and an outer side corresponding to the gate stack, and at least one outer sides laterally contacts the first semiconductor material of the substrate.
