Manipulators and semiconductor processing equipment

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...

AI Technical Summary

Problems solved by technology

[0005] In the process of adjusting the rotation angle of the mechanical finger 2, the rotation angle of the mechanical finger 2 is adjusted by manually turning the mechanical finger 2, the adjustment accuracy is low, and it is easy to adjust excessively, so that the fastening screw 3 needs to be repeatedly loaded and unloaded, resulting in a complicated adjustment process
