This invention discloses a laser-direct-write magnetic thin-film encapsulation method for chip-based inductive elements, relating to the field of integrated circuit packaging technology. The method involves uniformly mixing magnetic nanoparticles with a curable adhesive to form a magnetic slurry, which is then uniformly coated onto a chip containing an inductive element. A laser is used to directionally irradiate the magnetic slurry above the inductive element, causing it to solidify and form a magnetic thin film that adheres tightly to the chip. Uncured magnetic slurry on the chip is then cleaned away, resulting in an inductive element encapsulated with the magnetic thin film. This method solidifies the magnetic film within a designated area of ​​the chip's inductive element, avoiding direct contact with the element's surface. This prevents chip interface damage and device failure, as well as issues such as secondary diffusion failure of active devices due to excessive temperature. It is fully compatible with standard semiconductor processes, facilitating commercial applications. The encapsulation process is simple, efficient, and flexible.
