PVD stands for Physical Vapor Deposition, and thermal evaporation is a specific example of a PVD process. This method involves the evaporation of a solid material in a vacuum environment to form a thin film on a substrate.
What does PVD stand for in thermal evaporation? 4 Key Points to Understand
1. Physical Vapor Deposition (PVD)
PVD is a group of processes used to deposit thin films and coatings on various substrates.
These processes involve the transformation of a material from its condensed phase (solid or liquid) to a vapor phase and then back to a condensed phase in the form of a thin film on a substrate.
The primary methods within PVD include sputtering and evaporation.
2. Thermal Evaporation as a PVD Process
Thermal evaporation is one of the simplest and most popular forms of PVD.
It operates by heating a solid material in a high vacuum chamber until it reaches its vapor pressure.
The evaporated material then travels through the vacuum chamber and deposits as a thin film on the substrate.
This method is favored for its simplicity and speed, making it suitable for applications such as decorative coatings, OLEDs, solar cells, and thin-film transistors.
3. Characteristics and Applications of Thermal Evaporation
Thermal evaporation exhibits moderate film stress and can have lower film density, though this can be improved with ion-assist techniques.
The process is particularly useful for depositing metallic contact layers and can be applied in various sectors including automotive, medical, and aerospace for purposes like EMI/RFI shielding and light reflectors.
4. Comparison with Other PVD Methods
While thermal evaporation is known for its simplicity, it may not produce films with the highest quality in terms of density and impurity levels compared to other PVD methods like sputtering.
Sputtering involves the use of a plasma to eject atoms from a target material, which can result in more uniform and denser films.
