Magnetic Thermal Annealing is a successful method to improve the performance of magnetic materials and devices. Certain structural parameters must be taken into account when calculating the strength, ductility, and hardness of a solid. For a long time, metallurgy has employed annealing as a common process.
This time-tested technology, known as magnetic thermal annealing, adds a fresh perspective. The main distinction between the two heat treatments is that magnetic annealing applies an external magnetic field while the material is being heated. This has some extremely intriguing consequences, particularly on materials that are ferromagnetic (FM) and antiferromagnetic (AFM).
The Global Magnetic Thermal Annealing system market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
In comparison to thermal annealing, the micro VEGA x MR has a number of benefits for the development of magnetic sensors. These include the capacity to set various reference magnetization orientations on sensors across a single wafer and improved precision to enable the production of smaller magnetic device architectures, which results in more devices per wafer.
In order to “imprint” the appropriate magnetic orientation, the system’s on-the-fly spot and variable laser energy selectively heat the pinning layer in each sensor.
High-temperature gradients ensure little thermal effect while allowing for recipe-based adjustment of magnetic field intensity and orientation.
This enables the manufacturing of smaller sensors, freeing up room for processing more devices per wafer, and enables the processing of sensors next to read-out circuitry as well as closer together. Incorporated monolithic sensor packages can now be produced with fewer steps in the process, a simpler production process, a higher yield, and at a lower cost.
As part of 3D-continued Micromax’s strategy to target markets with high growth potential that are future-focused, the microVEGA xMR system is a significant accomplishment. It is supported by its process knowledge and applications services.
They are happy to have had the chance to collaborate with Crocus Technology on one of the first installations of this innovative product, where they were able to benefit from their extensive capabilities, which include application and process development as well as contract production.
