Vacuum requirements for different semiconductor processes
- Photolithography process
- General photolithography: 10^-3 ~ 10^-5 Pa
- EUV lithography: 10^-7 ~ 10^-9 Pa
- Thin film deposition process
- Physical vapor deposition (PVD): 10^-4 ~ 10^-6 Pa
- Chemical vapor deposition (CVD): 10^-4 ~ 10^-7 Pa
- Atomic layer deposition (ALD): 10^-6 ~ 10^-8 Pa
- Etching process
- Reactive ion etching (RIE): 10^-4 ~ 10^-6 Pa
- Deep reactive ion etching (DRIE): 10^-5 ~ 10^-7 Pa
- Ion implantation process
- Basic vacuum degree: 10^-5 ~ 10^-7 Pa
Why do we pursue ultra-high vacuum?
Impurity control
10^-7 Pa vacuum can significantly reduce the contamination of residual gas molecules (such as water, oxygen, hydrocarbons) to the process
Surface cleanliness
Under ultra-high vacuum, the time it takes for a surface contamination monolayer to form can be extended from a few seconds in ordinary high vacuum to several hours.
Yield improvement
Providing the necessary clean environment for 7nm and below process nodes
Uniformity assurance
ensuring the accuracy and uniformity of processes such as thin film deposition and ion implantation
Challenges of Vacuum Chamber Welding
· Leak rate requirements
Usually the leakage rate is required to be lower than 1×10^-10 Pa·m³/s.
· Material outgassing
Special treatment is required to reduce the release of gas from the material.
· Weld quality
There must be no micropores or impurities to ensure long-term vacuum integrity.
The key significance of leak rate indicator in vacuum system
Leak rate is the most critical indicator to measure the sealing integrity of the vacuum system, which directly determines whether the system can reach and maintain the designed vacuum degree. For semiconductor process equipment, even a small leak may cause:
- The basic vacuum degree cannot meet the standard, affecting the purity control of subsequent process gases.
- Pollutants such as moisture and oxygen in the atmosphere continue to penetrate, interfering with the uniformity of film deposition.
- The formation of the surface adsorption layer is accelerated, reducing the interface quality and structural characteristics.
- The residual gas composition in the process chamber changes, affecting the ionization efficiency and energy distribution.
Ultra-high vacuum sealing technology
Through years of focused research and development, Leku has transformed the extremely low leakage rate control capability of <1.0×10^-13 Pa·m³/s into a core competitive advantage, and can provide you with truly “ultra-high vacuum grade” products that meet the stringent requirements of the most advanced semiconductor processes.
