FAQ

What is Physical vapor deposition (PVD)?

Physical vapor deposition (PVD) is a technique for depositing thin films by vaporizing a solid material in a vacuum and then depositing it onto a substrate. PVD coatings are highly durable, scratch-resistant, and corrosion-resistant, making them ideal for a variety of applications, from solar cells to semiconductors. PVD also creates thin films that can withstand high temperatures. However, PVD can be costly, and the cost varies depending on the method used. For instance, evaporation is a low-cost PVD method, while ion beam sputtering is rather expensive. Magnetron sputtering, on the other hand, is more expensive but more scalable.

How are high-purity graphite crucibles made?

High-purity graphite crucibles are typically manufactured through a process called isostatic pressing. In this method, graphite powder is placed in a rubber mold, and then subjected to high pressure from all directions. This pressure compacts the graphite particles into a dense and uniform crucible shape. The crucible is then heated to a high temperature to remove any impurities and improve its purity.

What is magnetron sputtering?

Magnetron sputtering is a plasma-based coating technique used to produce very dense films with excellent adhesion, making it a versatile method for creating coatings on materials that have high melting points and cannot be evaporated. This method generates a magnetically confined plasma near the surface of a target, where positively charged energetic ions collide with the negatively charged target material, causing atoms to be ejected or "sputtered." These ejected atoms are then deposited on a substrate or wafer to create the desired coating.

What is sputtering target?

A sputtering target is a material used in the process of sputter deposition, which involves breaking up the target material into tiny particles that form a spray and coat a substrate, such as a silicon wafer.

Factors and Parameters that Influence Deposition of Thin Films

Deposition Rate:

The rate at which the film is produced, typically measured in thickness divided by time, is crucial for selecting a technology suitable for the application. Moderate deposition rates are sufficient for thin films, while quick deposition rates are necessary for thick films. It is important to strike a balance between speed and precise film thickness control.

Uniformity:

The consistency of the film across the substrate is known as uniformity, which usually refers to film thickness but can also relate to other properties such as the index of refraction. It is important to have a good understanding of the application to avoid under- or over-specifying uniformity.

Fill Capability:

Fill capability or step coverage refers to how well the deposition process covers the substrate's topography. The deposition method used (e.g., CVD, PVD, IBD, or ALD) has a significant impact on step coverage and fill.

Film Characteristics:

The characteristics of the film depend on the application's requirements, which can be categorized as photonic, optical, electronic, mechanical, or chemical. Most films must meet requirements in more than one category.

Process Temperature:

Film characteristics are significantly affected by process temperature, which may be limited by the application.

Damage:

Each deposition technology has the potential to damage the material being deposited upon, with smaller features being more susceptible to process damage. Pollution, UV radiation, and ion bombardment are among the potential sources of damage. It is crucial to understand the limitations of the materials and tools.

What is the lifetime of a sputtering target?
