Gold sputter coaters are essential tools for creating thin, even layers of gold on various substrates.
5 Key Steps Explained
1. Introduction to Sputtering
Gold sputter coaters work by using a process called sputtering. In this process, a target material, such as gold, is bombarded with energy. This energy causes the gold atoms to eject and deposit onto a substrate.
2. Excitation of Gold Atoms
The process begins with the excitation of gold atoms on the target. This is typically achieved by bombarding them with energy, such as argon ions.
3. Deposition onto Substrate
The bombardment causes the gold atoms to be ejected from the target. These atoms then deposit onto the substrate, forming a thin, even layer.
4. Control and Customization
Technicians can control the deposition process to create custom patterns and meet specific needs.
5. Applications in SEM
In the context of scanning electron microscopy (SEM), gold sputter coaters are used to deposit thin layers of gold or platinum onto samples. This improves conductivity, reduces electric charging effects, and protects the sample from the electron beam.
