Problems solved by technology

At the same time, due to the limited maintenance space in the housing 12, when the upper electrode part is partially opened, it is necessary to use a tool to unscrew the lock nut 182. During the operation, the tool is easy to hit the quartz window 14 and damage it; The use space of the tool is very limited, which makes the use of the tool more inconvenient, thus further prolonging the maintenance time of the equipment

Abstract

The invention discloses plasma processing equipment. An electrode opening mechanism of the processing equipment comprises a lifting component, wherein the outside part of the lifting component is installed on the inner wall of an electrode shell (22) of the plasma processing equipment and moves in the vertical direction driven by the electrode shell (22); the inside part of the lifting component is alternatively clamped with or separated from an adjusting bracket (23) of the plasma processing equipment in the vertical direction, thus the inclination of the adjusting bracket (23) caused in theprocess of reconnecting the lifting component and the adjusting bracket (23) can be avoided, the positioning reliability between a reaction cavity (0) and the lifted adjusting bracket (23) falling down again can be ensured, and then the positioning reliability of a top electrode closed again can be improved and the working performance of the plasma processing equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to a plasma processing equipment. Background technique [0002] With the rapid development of my country's economic construction, the market demand for various microelectronic components is increasing, which drives the rapid development of microelectronic technology. Plasma processing equipment is a typical microelectronic processing equipment, which is widely used in the field of microelectronic technology.
