Abstract
A breather assembly mounted to the purge port of a substrate carrier for coupling with a tool port. In various embodiments, the breather assembly comprises a grommet that presents either a planar or a concave mounting face for coupling to the tool port. In one embodiment, the grommet is of a 'solid compliant' construction, wherein the mounting face complies with the mouth of the tool port without substantially changing shape. In other embodiments, the grommet is of a 'flexible compliant' construction, wherein the grommet changes shape when engaged with the tool port. The grommet can be configured so that the force (pressure-area product) exerted in the direction towards the tool port is greater than the force exerted in the direction away from the tool port, thereby enhancing the seal between the grommet and the tool port.
