摘要： A process may include first etching a trench isolation dielectric through a dielectric hard mask that abuts the sidewall of a fin semiconductor. The first etch can be carried out to expose at least a portion of the sidewall, causing the dielectric hard mask to recede to a greater degree in the lateral direction than the vertical direction. The process may include second etching the fin semiconductor to achieve a thinned semiconductor fin, which has receded beneath the shadow of the laterally receded hard mask. The thinned semiconductor fin may have a characteristic dimension that can exceed photolithography limits. Electronic devices may include the thinned semiconductor fin as part of a field effect transistor.

摘要： Memory devices, such as DRAM memory devices, may include one or more metal layers above a local interconnect of the DRAM memory that make contact to lower gate regions of the memory device. As the size of semiconductor components decreases and circuit densities increase, the density of the metal routing in these upper metal layers becomes increasingly difficult to fabricate. By providing additional metal routing in the lower gate regions that may be coupled to the upper metal layers, the spacing requirements of the upper metal layers may be eased, while maintaining the size of the semiconductor device. In addition, the additional metal routing formed in the gate regions of the memory devices may be disposed parallel to other metal contacts in a strapping configuration, thus reducing a resistance of the metal contacts, such as buried digit lines of a DRAM memory cell.

摘要： Novel etch techniques are provided for shaping silicon features below the photolithographic resolution limits. FinFET devices are defined by recessing oxide and exposing a silicon protrusion to an isotropic etch, at least in the channel region. In one implementation, the protrusion is contoured by a dry isotropic etch having excellent selectivity, using a downstream microwave plasma etch.

摘要： In accordance with embodiments, there are provided mechanisms and methods for selecting a synchronous or asynchronous process to determine a forecast. 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.
