1、 Basic principle of magnetron sputtering cobalt iron boron plating

1.1 Magnetron Sputtering Technology

Magnetron sputtering technology is a method of depositing or modifying materials using high-speed ion bombardment. It places the target material in a vacuum chamber, applies a certain magnetic field and external electric field, and uses an ion beam to bombard the target material, causing atomic or molecular sputtering on the surface of the target material. By controlling the energy and angle during the sputtering process, a thin film can be formed on the substrate.

1.2 Advantages of Cobalt Iron Boron Plating

Cobalt iron boron (CoFeB) is a magnetic material with high magnetic permeability and high coercivity, which has a wide range of potential applications in magnetic fields. Compared to other magnetic materials, cobalt iron boron has higher coercivity and faster magnetization speed, making it an important material in fields such as magnetic memory, sensors, and motors.

2、 Preparation process of cobalt iron boron coating by magnetron sputtering

2.1 Material Preparation

The primary step in magnetron sputtering cobalt iron boron plating is to prepare suitable target materials. The target material is usually composed of three elements: Co, Fe, and B, and their proportions need to be adjusted according to the requirements of the application. The purity and uniformity of the material are crucial for the quality of the film, therefore careful acceptance and control are required during the material preparation process.

2.2 Sedimentary Process

When the ion beam bombards the target material, the atoms or molecules of the target material will be sputtered onto the substrate surface, forming a thin film. By adjusting parameters such as ion beam energy, sputtering time, and angle, the thickness and microstructure of the film can be controlled.

2.3 Post processing

After magnetron sputtering cobalt iron boron plating is completed, appropriate post-treatment processes are also required. The purpose of post-processing is to achieve better crystallinity and magnetic properties of the film. The commonly used post-processing methods include annealing and magnetic field treatment. By adjusting the temperature and processing time, the magnetization strength and stability of the film can be improved.
