Abstract
Techniques and mechanisms for cooling a substrate in a processing chamber by a bi-directional cooling process prior to transferring the substrate outside the processing chamber are provided. First cooling gas is introduced into the processing chamber from an upper gas source in a downward direction towards the upward facing surface of the substrate. An apparatus is placed underneath and in proximity to the substrate. Second cooling gas is introduced from the apparatus into the processing chamber in an upward direction towards the downward facing surface of the substrate. One or more gaps are cut out of the body portion of the apparatus, the gaps configured to allow the apparatus to avoid contact with the support structure holding the substrate, as the apparatus is moved in a horizontal direction into position underneath the substrate during placement of the body portion of the apparatus in proximity to the substrate.
