Target
In vacuum technology, the term "target" refers to the material that is to be applied to the substrate during the coating process. Targets are usually metal or ceramic plates that contain the desired coating material. These plates are placed in the vacuum chamber and are the target for vaporization or ion bombardment during the coating process.
The choice of target depends on the specific requirements of the coating. For example, targets can be made of different metals such as aluminum, copper, gold or silver, depending on the desired properties of the coating. In addition, ceramic targets can also be used to create oxide or nitride layers.
During the coating process, the target is treated by various methods to release the coating material. This can be done by thermal evaporation, sputtering or other techniques tailored to the desired coating thickness and quality.
Targets are crucial for the quality and functionality of the coated products. Selecting the right target and precisely controlling the coating process are crucial to achieving high-quality coatings with the desired properties.
