摘要: Generally, a robot for transferring a substrate in a processing system is provided. In one embodiment, a robot for transferring a substrate in a processing system includes a body, a linkage and an end effector that is adapted to retain the substrate thereon. The linkage couples the end effector to the body. The end effector and/or the linkage is comprised of a material having a coefficient of thermal expansion less than 5null10null6 Knull1. In another embodiment, the end effector and/or the linkage is comprised of a material having a ratio of thermal conductivity/thermal expansion greater than 1null107 W/(mnullK2). In yet another embodiment, the end effector and/or the linkage is comprised of a material having a ratio of thermal conductivity/thermal expansion greater than 1null107 W/(mnullK2) and a fracture toughness greater than 1null106 Pa m0.5.
