Asahi Kasei Microdevices (AKM) just earned a huge honor, as the company ints official press release states that the IEEE has named their 1983 thin-film Hall elements an official IEEE Milestone, recognizing groundbreaking electrical engineering achievements that have shaped our world.
Back in the ’80s, early Hall sensors struggled with low sensitivity and thermal instability, making mass production a nightmare.
AKM cracked it by placing a thin indium antimonide (InSb) layer between ferrites to focus magnetic flux and boost detection power. They then added a clever three-layer electrode structure for reliable gold wire bonding, solving the durability issues.

Their HW Series kicked off mass production of magnetic sensors, powering brushless motors in PC/server cooling fans and paving the way for smaller, more efficient IT gear and consumer electronics.
It’s also helped create energy-saving HVAC and refrigeration systems.
Today, you’ll find AKM’s Hall tech everywhere from smartphone cameras and EV efficiency gains to precision position detection and current sensing. They’ve even spun it into infrared sensors and LEDs.
This milestone celebrates 40+ years of magnetic sensing evolution that quietly made our gadgets smarter, greener, and more reliable.
Leadership Comment
Satoshi Takehara, Executive Officer of Asahi Kasei Microdevices, commented, “We are grateful to our customers for their longstanding trust in our thin-film high-sensitivity Hall elements, as well as to our suppliers and stakeholders for their continued support throughout many years of production. This IEEE Milestone recognition encourages us to further strengthen the quality and reliability of our products while advancing technological development that meets the evolving needs of society.”
Asahi Kasei positions Electronics as a First Priority business in its medium-term management plan.
This recognition illustrates Asahi Kasei’s long-term commitment to driving long-term, sustainable growth through its electronic materials and components.
