Usage&Features

The following are typical application scenarios and examples:

1. Semiconductor industry

Chip manufacturing (photolithography, etching, deposition)

In plasma etching machines or chemical vapor deposition (CVD) equipment, the stainless steel chamber maintains a low vacuum (10 ⁻³ -10 ⁻⁶ Pa) to ensure the purity of the process gas.

Ion implanter

The vacuum chamber prevents impurity contamination and ensures precise ion beam injection into the wafer.

2. Aerospace

Spacecraft simulation testing

Simulate a space ultra-high vacuum environment on the ground (such as 10 ⁻⁷ Pa) to test the performance of satellite or telescope components (such as the mirror calibration of the James Webb Telescope).

rocket propulsion system

The fuel storage tank and propellant pipeline are equipped with stainless steel vacuum chambers to prevent oxidation or leakage.

3. Medical and Biotechnology

Electron Microscopy (SEM/TEM)

The sample chamber requires high vacuum (10 ⁻⁴ -10 ⁻⁷ Pa) to avoid electron beam scattering, and the stainless steel chamber ensures imaging clarity.

Proton therapy (cancer radiotherapy)

The accelerator vacuum chamber ensures that there is no energy loss during the transmission of the proton beam.

4. New energy

Nuclear fusion devices (such as Tokamaks)

A vacuum chamber (such as ITER's stainless steel vacuum chamber) is used to confine high-temperature plasma, requiring a vacuum degree of 10 ⁻⁵ Pa or higher.

Lithium ion battery production

The drying and packaging process of electrode materials requires a low vacuum environment to prevent moisture and oxygen contamination.

6. Precision manufacturing

Thin film coating (optical, decorative coating)

In magnetron sputtering or vapor deposition equipment, the stainless steel chamber maintains a vacuum (10 ⁻² -10 ⁻⁵ Pa) to achieve uniform coating.

vacuum brazing

When welding precision components such as aircraft engine blades, vacuum prevents oxidation and enhances weld strength.
