Abstract

One or more techniques or systems for ultra-high vacuum (UHV) wafer processing are provided herein. In some embodiments, a vacuum system includes one or more cluster tools connected via one or more bridges. For example, a first cluster tool is connected to a first bridge. Additionally, a second cluster tool is connected to a second bridge. In some embodiments, the first bridge is configured to connect the second cluster tool to the first cluster tool. In some embodiments, the second cluster tool is connected to the first bridge, thus forming a 'tunnel'. In some embodiments, the second bridge comprises one or more facets configured to enable a connection to an additional process chamber or an additional cluster tool. In this manner, a more efficient UHV environment is provided, thus enhancing a yield associated with wafer processing, for example.
