Problems solved by technology

[0004] However, the existing magnetic field-induced deposition methods cannot be applied to production equipment for preparing magnetic thin films, such as PVD equipment
That is to say, the existing film deposition chamber does not have the function of inducing the in-plane anisotropy of the magnetic film

Abstract

The invention provides a magnetic film deposition chamber and a film deposition device. The magnetic film deposition chamber comprises a cavity body. The cavity body is internally provided with a base. The base comprises a bearing surface used for bearing a workpiece to be machined. The magnetic film deposition chamber further comprises a bias magnetic field device. The bias magnetic field device comprises a first magnet set. The first magnet set is arranged below the base and used for forming a first horizontal magnetic field above the base. The first horizontal magnetic field is used for enabling a magnetic film deposited on the workpiece to be machined to have in-plane anisotropy. By adopting the magnetic film deposition chamber provided by the invention, the horizontal magnetic field which is enough to induce the in-plane anisotropy can be formed on the base. The requirements for preparing magnetic films with the in-plane anisotropy on large-size workpieces to be machined by production equipment are met.

Description

technical field [0001] The present invention relates to the technical field of microelectronics, in particular to a magnetic thin film deposition chamber and thin film deposition equipment. Background technique [0002] With the development of technology, the integrated circuit manufacturing process can significantly reduce the size of the processor, but there are still some core components such as integrated inductors and noise suppressors that face many difficulties in high frequency, miniaturization, and integration. . In order to solve this problem, soft magnetic thin film materials with high magnetization, high magnetic permeability, high resonance frequency and high resistivity have attracted more and more attention. [0003] Although soft magnetic thin film materials mainly consider its high magnetic permeability and high magnetization strength, as well as low coercive force and low loss, a major factor affecting the development of soft magnetic thin film materials i...
