Abstract
Semiconductor processing tools are provided that include an upper support framework, a plurality of semiconductor processing chambers arranged along a first axis, a linear guide system fixedly supported by the upper support framework and extending along a second axis substantially parallel to the first axis, and a carriage. Each chamber has a base portion fixedly mounted relative to the upper support framework and a removable top cover with one or more hoisting features. The carriage includes a hoist arm configured to pivot about a vertical axis that is substantially perpendicular to the second axis, the carriage is configured to movably engage with the linear guide system and translate along the second axis relative to the linear guide system. The carriage and hoist arm are movable such that a hoist feature engagement interface of the hoist arm can be moved engage with hoisting features of any of the removable top covers.
