STORAGE ENVIRONMENT MONITORING SYSTEM AND METHODS OF OPERATION

A storage environment monitoring device is capable of measuring and/or monitoring various parameters of an environment inside a storage area, such as airflow, temperature, and humidity, to increase the storage quality of semiconductor components stored in the storage area. The storage environment monitoring device is capable of measuring and/or monitoring the parameters of the environment inside the storage area without having to open an enclosure that is storing the semiconductor components in the storage area. This reduces exposure of the semiconductor components to contamination and other environmental factors. In addition, the storage environment monitoring device may perform automatic measurements inside the storage area based on usage schedules of the semiconductor components that are to be stored in the storage area, which decreases downtime of the storage area and/or the semiconductor components, and increases productivity in a semiconductor processing environment in which the semiconductor components are used.

METHOD AND DEVICE FOR CLEANING SUBSTRATES

In a method of manufacturing a semiconductor device a semiconductor wafer is retrieved from a load port. The semiconductor wafer is transferred to a treatment device. In the treatment device, the surface of the semiconductor wafer is exposed to a directional stream of plasma wind to clean a particle from the surface of the semiconductor wafer. The stream of plasma wind is generated by an ambient plasma generator and is directed at an oblique angle with respect to a perpendicular plane to the surface of the semiconductor wafer for a predetermined plasma exposure time. After the cleaning, a photo resist layer is disposed on the semiconductor wafer.

PATTERN DECOMPOSITION LITHOGRAPHY TECHNIQUES

Techniques are disclosed for realizing a two-dimensional target lithography feature/pattern by decomposing (splitting) it into multiple unidirectional target features that, when aggregated, substantially (e.g., fully) represent the original target feature without leaving an unrepresented remainder (e.g., a whole-number quantity of unidirectional target features). The unidirectional target features may be arbitrarily grouped such that, within a grouping, all unidirectional target features share a common target width value. Where multiple such groupings are provided, individual groupings may or may not have the same common target width value. In some cases, a series of reticles is provided, each reticle having a mask pattern correlating to a grouping of unidirectional target features. Exposure of a photoresist material via the aggregated series of reticles substantially (e.g., fully) produces the original target feature/pattern. The pattern decomposition techniques may be integrated into any number of patterning processes, such as litho-freeze-litho-etch and litho-etch-litho-etch patterning processes.
