What are the types of target materials!


What are the target materials? Target is actually a broad concept, and there are three classification methods for target materials: 1. According to their external dimensions, they can be divided into cylindrical, rectangular, square plate targets, and tube targets; 2. Target materials can be divided into conventional metal target materials, precious metal target materials, rare earth metal target materials, non-metallic target materials, alloy sputtering target materials, ceramic sputtering target materials, etc; 3. According to the application field, it can be divided into semiconductor target materials, display panel target materials, solar cell target materials, magnetic recording target materials, etc.

Classified by target material shape:

Common target materials are mostly square targets and round targets, both of which are solid target materials. In the coating operation, the magnetic field generated by the circular permanent magnet on the surface of the target material is circular, which can cause uneven erosion. The thickness uniformity of the sputtered film is poor, and the utilization efficiency of the target material is only about 20% to 30%. The currently promoted hollow tube target can rotate around a fixed strip magnet component for a certain period of time, and the 360 ° target surface can be uniformly etched, which has obvious advantages and increases the utilization rate to 80%.
