Problems solved by technology

[0009] At present, the method of placing the workpiece on the electrostatic chuck is difficult to ensure the accuracy of the position of the workpiece on the electrostatic chuck. Only by placing the parts to be processed accurately on the manipulator can the transfer position be determined more accurately, thus limiting the debugging process and reducing the processing efficiency

Abstract

The invention discloses a method for placing workpieces to be processed on a static chuck, which is characterized in that the wafer transfer position of a manipulator is determined by a locating device so that the workpieces to be processed can be quickly and accurately placed on the static chuck. The invention also discloses plasma processing equipment capable of using the method. The method or the device can finish the adjustment process in one step and avoid the repeated adjustments through the combination of naked eyes and manual operations, thereby greatly improving adjustment speed, saving a lot of adjustment time, and greatly enhancing the accuracy that the workpieces to be processed fall on the position of the static chuck; furthermore, the adjustment of a technical chamber can befinished without using the workpieces to be processed, thereby further improving working efficiency.

Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to a method for placing workpieces to be processed on an electrostatic chuck. The present invention also relates to a plasma processing device in which the above method can be used. Background technique [0002] With the popularity of microelectronic products, plasma processing equipment is more and more widely used in the field of microelectronic technology. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a typical plasma processing equipment. [0004] The plasma processing apparatus 1 generally comprises a housing 11 having a reaction chamber 12 therein. The top and bottom of the reaction chamber 12 are respectively provided with an upper pole plate 13 and an electrostatic chuck 14 correspondingly, and the upper pole plate 13 is isolated from the housing 11 by an insulating member 15; the top of the electrostatic chuck 14 can support the pie...
