How Sputtering Targets Are Used


Are you getting tired of chasing after that target for your postdoctoral research?

If so, you might be considering switching to another method for the experiment. Sputtering is one of the most convenient methods of obtaining a target.

There are many applications with sputtering targets. Today, we will review many different ways of sputtering targets.

Physical Vapor Deposition (PVD) Coatings

Sputtering targets are used in Physical Vapor Deposition (PVD) coatings. This creates thin films by bombarding the surface of a material with ions. The ions remove atoms from the target material. It is then deposited onto the surface of the substrate.

The deposited film has a range of properties that can be tailored to the needs of the application. The thickness of the film can be controlled by the duration of the sputtering process. The composition of the film can be controlled by the composition of the target material.

Solar Cell Application

It’s used to deposit a thin film of photovoltaic material onto the surface of a solar cell.

The targets are made of a high-purity material, such as silicon. It is then heated to a high temperature and then sputtered onto the surface of the solar cell.

The sputtering process produces a very thin film of photovoltaic material, which is used to absorb light and convert it into electricity.

Manufacturing Semiconductor Devices

Sputtering targets are also used in the fabrication of semiconductor devices.

Sputtering targets deposit thin films of material onto a substrate. Silicon wafer is usually the substrate used. The thin film created can manufacture semiconductor devices.

One of the sputtering processes is the Boron Sputtering Target. Boron-doped films have a variety of electrical properties, and they can be exploited and used in different device applications.

Organic Light Emitting Diodes (OLEDs)

Sputtering targets are also used in the production of OLEDs. OLEDs are light-emitting devices. These are made by depositing thin films of organic materials on a substrate.

The organic materials are deposited from a solution, but they can also be deposited from a vapor. In either case, the film is very thin on the order of a few nanometers.

Sputtering is a helpful deposition technique for OLEDs. The advantage of this is it can be used to deposit very thin films with good coverage.

Sputtering can be used to deposit films of multiple materials in a single step. This method is not possible with other deposition techniques. For this reason, it is an important part of the OLED manufacturing process.

Spacecraft, Medical Implants, and Others

Many industries use the sputtering target to apply hard coatings to their products. Common industries include the automotive, aerospace, and medical industries.

They use the sputtering target to improve the durability of their product. This increases the wear resistance and/or corrosion resistance of parts and products.

An example of this is coating spacecraft with reflective or protective coatings. This helps to protect the spacecraft from the harsh environment of space.

It is also used in the medical field. They coat implants and stents with a thin layer of biocompatible material which helps to create a strong bond between the implant and the surrounding bone. It also helps to prevent the implant from corroding.

The Future of Sputtering Targets

The future of sputtering targets looks bright as new and innovative uses for them are developed. The development of newer and more efficient sputtering technologies are opening up. This creates new possibilities for the application of sputtering targets in the future.
