MagnaChip secures magnetic field sensing technology for mobile, consumer, industrial and automotive applications

SEOUL, South Korea and CUPERTINO, Calif., June 16, 2014 /PRNewswire/ -- MagnaChip Semiconductor Corporation ("MagnaChip") (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, announced that it has signed a patent license agreement with SENIS AG, a manufacturer of magnetic field and current measurement instruments based in Zug, Switzerland.

With the agreement, MagnaChip acquires the right to use a portfolio of SENIS' patents covering magnetic field and current measurement technologies in its sensor products. MagnaChip expects the agreement to significantly strengthen the company's existing initiatives in sensors and allow development of sensor solutions for new industrial and consumer applications. MagnaChip's existing portfolio of sensors includes the e-Compass and MXM11XX Digital Hall sensor family. According to Gartner, non-optical semiconductor sensor revenue grew 5.9% in 2013 to $6.1 billion, and is expected to grow to $10.2 billion in 2018.

"We are pleased to reach a strategic alliance agreement with SENIS AG, a company that we have previously collaborated with in a close partnership," said YJ Kim, interim CEO of MagnaChip and General Manager of MagnaChip's Display Solutions Division. "With access to SENIS' high performance magnetic field and current measurement technology, we expect to accelerate development of differentiated sensor solutions for our customers, particularly in industrial applications."

SENIS and Its Founder Honored for Technical Achievements in Magnetic Sensing

SENIS AG, a developer of magnetic sensing and instrumentation systems based in Switzerland, has been receiving accolades for its Fast Magnetic Angle Sensor, known as FAMAS, and the technological achievements of its founder, Professor Radivoje Popovic. Amidst the pandemic, recognitions of the honors have taken unusual twists due to adjustments to Covid-19.

In June, SENIS was named winner of the AMA Innovation Award 2020 by the Association for Sensors and Measurement in Berlin for FAMAS. It is an integrated magnetic field sensor that allows the measurement of the rotation angle of the in-plane component of a magnetic field, such as that of a permanent magnet attached to a rotating shaft.

Due to the current situation, the award was endowed virtually instead of physically at the SENSOR+TEST trade fair as planned. The jury chairman along with the winners presented the individual projects using multimedia tools. The SENIS team is shown above accepting the award virtually.

In another recognition, the Intellectual Property Office has nominated Professor Radivoje Popovic, a founder, president and chief technology officer of SENIS, for its award in lifetime achievement of the European Inventor Award 2020.

Held each year by the Intellectual Property Office, this year’s judging and ceremony have been impacted also by Covid-19. The 2020 Award has been postponed until 2021. The finalists will be announced in May 2021 and the event will take place in Monaco on 17 June 2021.

Popovic has dedicated his career to the development of novel magnetic, current, and optical sensors, said IPO. He is named as inventor in 41 granted European patents. His inventions enabled for the first time the realization of integrated multi-axis magnetic sensors that are widely used in automotive industry, in mobile phones and in scientific research. He is a professor emeritus at the Swiss Federal Institute of Technology (EPFL) in Lausanne. Before joining EPFL as a professor of microtechnology systems, Popovic was vice president of Central R&D at Landis+Gyr in Zug.

Nano-scale traceable magnetic field measurement

SENIS is one of the few companies providing certified magnetic measurements that can be traced back to national standards. Measuring 3D magnetic fields at the micrometre scale has now been reduced in size by a factor of ten by the new commercial nano-Hall mapper. For the first time the capability exists in Europe for measuring fluctuating magnetic fields at the micro and nano scale level, essential to support the high technology industries of the future and help maintain Europe’s position in the global market for magnetic sensors.

During the EMPIR project Nano-scale traceable magnetic field measurements, SENIS AG developed a high-resolution nano-Hall mapper with a 50-nanometre positioning accuracy and a 1000 nanometre spatial resolution. Capable of a large scan range of several centimetres the new mapper features a compact Hall probe with a field sensitive volume of 10 micrometres x 10 micrometres x 10 micrometres, which is an order of magnitude smaller than any commercially available magnetic sensor. The new mapper can measure fluctuating magnetic fields with a 3D positioning resolution at the 50-nanometre level with a minimum field resolution better than 5 μT. The system was traceably calibrated at SENIS’s accredited laboratory and its performance validated using an electromagnet provided by PTB, Germany’s National Metrology Institute (NMI).

Hall-effect-based teslameters are the mostly applied instruments for measuring DC and AC magnetic flux densities in the range from a few uT to about 30T. SENIS 3D Teslameter that features very high magnetic resolution, high spatial resolution and high accuracy is presented in CERN Courier.

SENIS helps keep permanent magnets at optimum performance

The SENIS Magnetic Field Mapper doesn’t just provide magnetic field mapping, SENIS provides another type of probe that detects cracks in the magnets, known as eddy-current probes.

“Magnets, like all metals, are susceptible to cracking,” says Spasic. “When a crack forms in a magnet, they are usually too small to see with the naked eye.”
