摘要： The invention includes methods of forming electrically conductive material between line constructions associated with a peripheral region or a pitch region of a semiconductor substrate. The electrically conductive material can be incorporated into an electrically-grounded shield, and/or can be configured to create a magnetic field bias. Also, the conductive material can have electrically isolated segments that are utilized as electrical jumpers for connecting circuit elements. The invention also includes semiconductor constructions comprising the electrically conductive material between line constructions associated with one or both of the pitch region and the peripheral region.

摘要： The present invention provides a method for fabricating improved integrated circuit devices. The method of the present invention enables selective hardening of gate oxide layers and includes providing a semiconductor substrate having a gate oxide layer formed thereover. A resist is then formed over the gate oxide layer and patterned to expose one or more areas of the gate oxide layer which are to be hardened. The exposed portions of the gate oxide layer are then hardened using a true remote plasma nitridation (RPN) scheme or a high-density plasma (HDP) RPN scheme. Because the RPN scheme used in the method of the present invention runs at low temperature, the patterned resist remains stable through the RPN process, and those areas of gate oxide layer which are exposed by the patterned resist are selectively hardened by the RPN treatment, while those areas covered by the patterned resist remain unaffected. The method of the present invention is extremely adaptable and may further include additional thermal oxidation steps used to thicken non-hardened portions of the gate oxide layer, as well as additional masking, and hardening steps, which may provide multiple hardened or non-hardened portions of varying thicknesses within a single gate oxide layer. Thus, the method of the present invention may be used to fabricate an IC device having selectively hardened N-channel and P-channel devices having gate oxides of varying thickness.

These mechanisms and methods for such synchronous/asynchronous process selection can enable embodiments to determine forecasts for multiple users (e.g. with hierarchical relationships, etc.) over an arbitrary time interval. The ability of embodiments to provide forecasts that involve such a large amount of data in an effective way can enable forecasting that was otherwise infeasible due to resource limitations.
