Abstract
An end-effector with integrated cooling features comprises heat transferring mechanisms that transfer heat energy away from the end-effector. The end-effector advantageously minimizes the cooling overhead of a processed substrate as it is transported from a process module to a low-cost storage cassette. The reduced cooling overhead of the processed substrate, as a consequence, improves substrate throughput. In the preferred embodiments, the heat transferring mechanisms include a high surface area heat sink connecting the substrate-supporting paddle with a robot arm. Cooling fins can enhance surface area and thus enhance heat dissipation from the heat sink. Cooling channels can extend through paddle and heat sink, either containing circulating fluid for carrying heat beyond the end-effector or a phase changing material in an enclosed heat pipe.
