Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the manipulator and semiconductor processing equipment provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Figure 3A It is a top view of the manipulator provided by the first embodiment of the present invention. see Figure 3A , the manipulator includes a finger mounting plate 10 and a mechanical finger 11 mounted thereon, and the mechanical finger 11 can rotate around a rotation center 110 in a horizontal plane relative to the finger mounting plate 10 . The horizontal plane is parallel to the surface of the robotic finger 11 for carrying the wafer.

[0030] The manipulator also includes an angle adjustment mechanism, which is used to adjust the rotation angle of the manipulator finger in a threaded manner. The rotation angle can be regarded as the angle between the current position ...

Abstract

The invention provides a mechanical arm and a semiconductor processing apparatus. The mechanical arm comprises a finger mounting plate, a mechanical finger mounted thereon, and an angle adjustment mechanism, wherein the mechanical finger is rotatable in a horizontal plane relative to the finger mounting plate. The angle adjustment mechanism is configured to adjust the rotation angle of the mechanical finger by a screw-thread fit way. The mechanical arm can reduce the amount of angle adjustment of the mechanical finger, thereby avoiding excessive adjustment, improving adjustment precision, simplifying an adjustment process, and reducing the probability of wafer displacement.

Description

technical field [0001] The invention relates to the field of semiconductor manufacturing, in particular to a manipulator and semiconductor processing equipment. Background technique [0002] In the wafer etching process in the fields of integrated circuits, semiconductor lighting, micro-electromechanical systems, etc., plasma dry etching equipment is usually used to complete the wafer etching process. In order to improve the degree of automation and safety of equipment, wafers are generally transported by manipulators or other automated devices. [0003] figure 1 It is a top view of the existing manipulator. see figure 1 , the manipulator includes a finger mounting plate 1 and a mechanical finger 2 mounted thereon, and the mechanical finger 2 can rotate relative to the finger mounting plate 1 in a horizontal plane. Moreover, the manipulator also includes a plurality of fastening screws 3 which are arranged around the rotation center of the manipulator finger 2 to fix the...
