Why is CVD better than PVD? 4 Key Advantages

CVD (Chemical Vapor Deposition) is often considered superior to PVD (Physical Vapor Deposition) due to several key advantages.

4 Key Advantages of CVD Over PVD

Why is CVD better than PVD? 4 Key Advantages

1. Higher Operating Pressures

CVD operates at higher pressures than PVD.

This eliminates the need for high vacuum pumps.

It reduces the cost if the system does not require extensive gas management for toxic gases.

2. Non-Line-of-Sight Deposition

The higher pressure, combined with the laminar flow properties of CVD, allows for non-line-of-sight deposition.

This enables conformal films to be deposited on substrates with irregular surfaces or in densely packed arrangements.

3. High Purity and Dense Films

CVD can produce highly pure and dense films or particles at relatively high deposition rates.

This capability is crucial for applications requiring uniform coating and high purity.

CVD also excels in its versatility, being able to deposit a wide range of materials including metallic, ceramic, and semiconducting thin films.

4. Economic Benefits

CVD offers economic benefits and reduces the need for high vacuum conditions.

This enhances the attractiveness of CVD for many applications.
