Abstract
Description
Technical Field
[0001] This invention relates to the field of chip processing technology, and in particular to a chip wet etching machine that is easy to adjust. Background Technology
[0002] Wafers are the basic material for manufacturing semiconductor chips. Wet etching removes the surface material of silicon wafers using chemical reagents. Generally, wet etching is performed on a wet etching machine, which mainly includes an etching unit, a washing unit, and a drying unit. However, current etching units use a suction cup to pick up and fix the wafer before spraying the etching solution. When the wafer is in place, the suction cup rises to pick up the wafer and sprays the etching solution from above. After etching, the wafer is sent out of the cavity. During operation, the wafer above the suction cup often breaks, causing a large amount of etching solution to enter the vacuum pipe, solenoid valve, etc., which can cause serious damage to the equipment. After etching, the wafer needs to be washed with water. Currently, the water washing equipment mainly involves spraying the surface of the wafer with spray nozzles inside the water washing chamber after the wafer enters the water washing chamber. The wafer is washed during the transportation process.
[0003] However, the existing wet etching machine has a relatively simple external structure, and it cannot be freely adjusted according to the actual installation environment, thus affecting the installation efficiency of the wet etching machine. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that the external structure of existing wet etching machines is relatively simple and that wet etching machines cannot be freely adjusted according to the actual installation environment, and to propose an easily adjustable chip wet etching machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easily adjustable chip wet etching machine includes a mounting base, a load-bearing plate, and a wet etching machine body.

[0011] Preferably, the bottom of the mounting base is fixedly connected with a plurality of locking blocks, and the locking blocks are provided with locking holes.
[0012] Preferably, the inner wall of the mounting groove is provided with a support groove corresponding to the pad, a fixing rod is fixedly connected in the support groove, and the pad is provided with a through opening corresponding to the fixing rod.
[0013] Preferably, a vertical rod is fixedly connected inside the slide groove, and the slider is provided with a sliding opening corresponding to the vertical rod. Multiple balls are slidably connected inside the sliding opening, and the edges of the balls are in contact with the vertical rod. Beneficial effects
[0014] 1. In this invention, the rotating rod is driven to rotate by the knob, and then the lead screw is driven to rotate by the meshing action between the first gear and the second gear, thereby driving the load-bearing plate to move up and down through the slider, adjusting the height of the wet etching machine body. At the same time, the setting of the L-shaped clamp and the clamp block can facilitate the disassembly and maintenance of the wet etching machine body. 2. In this invention, the wet etching machine can be freely adjusted according to actual installation needs by setting multiple adjustment mechanisms, thereby effectively improving the installation efficiency of the wet etching machine; 3.
