Technical Field
[0001] This invention relates to the field of semiconductor vacuum equipment technology, and more specifically to a device and method for disassembling and assembling internal components of a semiconductor vacuum equipment. Background Technology
[0002] With the rapid development of the semiconductor industry, semiconductor vacuum equipment (such as etching machines, PECVD, vacuum coating machines, and ion implanters) is the core equipment for chip manufacturing. The connection accuracy and cleanliness of its internal components (vacuum chamber flanges and bushings, positioning pins and chambers, electrodes and bases, vacuum bearings and drive shafts, sealing rings and chambers) directly determine the chip manufacturing process accuracy and equipment operation stability.
[0003] Interference fit, as a connection method that can meet the requirements of "high rigidity, high coaxiality, and high sealing" in such equipment, has become the preferred assembly form for core components due to its advantages of zero gap, vibration resistance, and large transmission torque. However, the extreme special nature of the semiconductor vacuum scene makes traditional assembly and disassembly techniques and tooling completely unsuitable, and the need for technology upgrades is urgent.
[0004] Current tooling lacks cleanliness and contamination control, resulting in severe particulate contamination. Traditional tooling often uses ordinary carbon steel and plastic parts, which are prone to rust, wear, and shedding of metal shavings and plastic particles. Mechanical impacts can also generate breakage particles and damage components. Auxiliary media used during hot / cold assembly (such as heating oil and liquid nitrogen residue) can adhere to the surface of parts, making thorough cleaning difficult and affecting component sealing. Furthermore, it lacks portability, often featuring fixed structures without modular design, making it impossible to disassemble and adapt.

[0055] Example 2: exist Figure 1 , Figure 2 , Figure 3 In the illustrated embodiment, a semiconductor vacuum equipment internal component disassembly and assembly device is mainly used for the installation and removal of interference-fit components. It is adaptable to the assembly of different components through replaceable mounting heads. The metal parts of this tooling are made of 316L stainless steel, and all metal parts except the threaded parts are 400# mirror polished to ensure cleanliness.

The C-shaped clips 41 can slide along the housing limiting groove 14 to adjust the circumferential position of the C-shaped clips 41 relative to the device housing 1. The U-shaped pads 42 are snapped onto the free end of the C-shaped clips 41. The U-shaped pads 42 are made of PTFE-type material.
[0065] The outer casing 1, transmission lifting mechanism, fixing mechanism, and C-shaped clamp of the device are all made of 316L stainless steel.
[0066] The internal component disassembly and assembly device of this semiconductor vacuum equipment achieves smooth lifting and pressing operations through the transmission handle and rotating disk during use. It is stably connected to the transmission lifting mechanism through the fixing mechanism and ensures that the lower end does not rotate with the transmission lifting mechanism during the rotation lifting and pressing process.

[0073] Then, install the entire disassembly and assembly device at the position of the vacuum bearing to be installed, and press the annular washer 15 onto the surface of the vacuum equipment. At the same time, the U-shaped pad on the C-clamp 41 can also form a clamping fit with other surfaces of the vacuum equipment.
[0074] The vacuum bearing is gripped by a three-jaw jack 54 and leveled to ensure gripping accuracy.
[0075] Finally, place the transmission handle 21, which drives the transmission screw 222 to rotate. The rotation of the transmission screw 222 drives the three-jaw pick 54 and the vacuum bearing to move together, thereby slowly and smoothly removing the vacuum bearing.
[0076] Other types of interference-fit components, such as flanges, bushings, and magnetorheological fluid components, can have appropriate mounting heads selected based on actual conditions. By changing the mounting head with the corresponding structure, different types of components can be installed and clamped conveniently and quickly. Simultaneously, the pressure display and universal level allow observation of the applied pressure and levelness during installation, ensuring installation accuracy.
