The present invention generally provides a batch processing system having a processing chamber and a loading chamber. Substrates are transferred in and out the processing chamber in a batch by a substrate boat. A batch handling tool of the present invention is generally used in the loading chamber to load and unload the structured substrate support by group. The batch handling tool generally comprises a support member, which is configured to host at least two sets of support blades. The at least two sets of substrate supports are generally mounted on the support member and their positions are switchable when the support member rotates. Each set of the support blades is configured to load (unload) at least two substrates into(from) the substrate boat.
