摘要： A substrate transport device includes an arm, an end effector coupled to the arm, a driver configured to lift the arm so that the end effector receives a substrate, and a controller configured to control an output of the driver to change a lifting speed of the arm. While lifting the arm at a first speed to lift the end effector toward the substrate, the controller changes the lifting speed to a second speed that is lower than the first speed when the end effector starts to raise a height position of the substrate.

摘要： A vacuum processing apparatus having a small installation area is provided. A lifting plate is arranges inside a vacuum chamber, and a substrate holding device is arranged on the lifting plate to be able to be lifted up and down. An upper side processing device and a lower side processing device are provided in a processing region located beside a lifting region where the lifting plate moves up and down. An upper side moving device and a lower side moving device make the substrate holding device pass through the processing region, and a transfer device transfers the substrate holding device between the upper side moving device or the lower side moving device and the lifting plate. Because vacuum processing can be performed on the upper side and the lower side, the installation area of the vacuum processing apparatus is small.

摘要： A substrate transport device includes an arm, an end effector coupled to the arm, a driver configured to lift the arm so that the end effector receives a substrate, and a controller configured to control an output of the driver to set a lifting speed of the arm. A difference in height between the end effector and the arm is a position difference. A period from when the end effector contacts the substrate until the end effector completes reception of the substrate is a transition period. The controller sets an upper limit value of the lifting speed that decreases an amplitude of one of acceleration or jerk of the position difference in the transition period as compared to before the transition period to an upper limit value of the lifting speed for the transition period.
