Industrial robot
The present invention is to provide an industrial robot, which is placed in vacuum for use, capable of efficiently cooling down hand- or arm-driving motors which are arranged inside the arm in air. The industrial robot is provided with a motor for rotating a second arm unit with respect to a first arm unit, a motor for rotating a hand with respect to the second arm unit, a reduction gear for reducing the rotation of the motor and transmitting it to the second arm unit, and a reduction gear for reducing the rotation of the motor and transmitting it to the hand; the hand and the arm are placed in vacuum. The reduction gears and are coaxially arranged so that the center of rotation of the second arm unit with respect to the first arm unit coincides with the axial centers of the reduction gears. The interior space of the hollow first arm unit is kept at atmospheric pressure in which the motors and the reduction gears are arranged.
Carrier plate assembly for a wafer
A carrier plate assembly has a carrier plate and multiple gaskets. The carrier plate has a first end, a second end, and a carrier surface between the first end and the second end. The carrier surface forms multiple accommodating recesses. The gaskets are accommodated in the accommodating recesses. The gaskets prevent the wafer from sliding. Besides, with top surfaces of the gaskets aligning with the carrier surface and an edge of each gasket connected to an edge of an opening of the accommodating recess, the accommodating recess is filled by the gasket, and thus the gasket is securely accommodated in the accommodating recess and may not deform upward.
