Abstract

The invention provides a leveling device and a reaction chamber. The leveling device comprises an elastic connecting piece, at least three leveling screws and a leveling plate for bearing supporting columns, wherein the leveling plate is elastically connected with the bottom wall of the chamber through the elastic connecting piece; at least three threaded holes penetrating through the leveling plate in the thickness direction of the leveling plate are formed in the leveling plate at intervals in the circumferential direction of the leveling plate; and the leveling screws are matched with the threaded holes in a one-to-one correspondence mode, and the lower end of each leveling screw abuts against the bottom wall of the chamber. According to the leveling device and the reaction chamber provided by the invention, a plurality of supporting columns can be leveled conveniently and quickly, the leveling time is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor equipment, in particular to a leveling device and a reaction chamber. Background technique [0002] At present, in semiconductor equipment, the chamber is usually provided with a base for carrying the substrate during the process, and a plurality of support columns that can pass through a plurality of through holes distributed in the base. A plurality of support columns in the middle lift the substrate, so that there is a certain distance between the substrate and the base, so that the manipulator can have space to enter the lower surface of the substrate to pick and place the substrate. In order to ensure the quality of film formation on the substrate, the base and multiple support columns need to be adjusted to the level. [0003] The bottoms of the existing multiple supporting columns are in direct contact with the bottom surface of the chamber, and the level of the bottom surface of the...
