We continue our Advanced Sensor webinar series with dual webinar presentations from technical leads at Twinleaf and 3D-Micromac, covering advanced magnetic sensor design and fabrication.
These amazing devices play a critical role in measuring what we cannot see by their ultra-sensitivity to magnetic currents. Thinking about adding a magnetic sensor to extend the functionality of your device? Then this is the webinar series for you.
Join these technology experts to see how magnetic sensors work, are built and how to utilize them in your products or research.

Wafer Fabricated Atomic Reference Cells
Tom Kornack, Chief Scientist, Twinleaf LLC
Abstract: Quantum sensing often uses atomic systems in vapor phase. This talk will briefly review Twinleaf’s wafer-scale atomic vapor cell fabrication capabilities and some of the applications that have been addressed.
Speaker Bio: Dr. Kornack is an expert in the design, fabrication and operation of atomic magnetometers. At Twinleaf, he has commercialized a wide variety of high performance magnetic field sensors. As a graduate student and a postdoctoral research assistant working with the magnetometer research group at Princeton University, he developed the first laser zero-field SERF magnetometer. He has also developed co-magnetometers for use as a sensitive gyroscope and as a probe into fundamental laws of physics.
Laser Based Magnetic Field Sensor Formation for GMR / TMR Sensor Arrays
Dr. Dirk Lewke, Team Leader Technology Innovation Management
Abstract: This presentation provides a deep inside into a laser-based annealing technology for GMR/TMR sensors, which enables the programming of advanced sensor structures at wafer level. The key feature is the combination of reaching the Curie-Temperature by applying a selective laser spot and an in-situ rotatable magnetic field while wafer travelling at high speed. Unique single sensor field programming enables high quality sensor read-out repeatability.
Speaker Bio: Dr. Dirk Lewke studied mechatronic engineering at the University of Erlangen-Nuremberg. He received his doctorate in 2017. From 2011 to 2017 he worked at Fraunhofer IISB in the field of semiconductor manufacturing equipment as a scientist. Since 2017, Dr. Lewke has been working working at 3D-Micromac as a team leader for process development and technology manager for laser production equipment for semiconductor and photovoltaic industry.
