SANTA CLARA, Calif.–(BUSINESS WIRE)–Hprobe, a provider of turnkey semiconductor Automatic Test Equipment (ATE) for magnetic devices, will present at the MRAM Developer Day 2019*, a new technology of magnetic generator for ultra-fast testing time (less than one second) of Magnetic Tunnel Junction (MTJ) for Spin Transfer Torque (STT) MRAM devices under perpendicular magnetic field at above 2 Tesla. This achievement represents a world premiere and the technology will be integrated in Hprobe ATE to drastically enhance the sorting flow of STT-MRAM wafers at major 300mm foundries.
STT-MRAM technology is an emerging non-volatile memory with target applications such as Micro Controller Unit (MCU), Internet of Things (IoT) Artificial Intelligence (AI) and 5G. According to Tom Coughlin, President of Coughlin Associates and co-author of Emerging Memories Ramp Up, by 2029, stand-alone MRAM and STT-MRAM revenues will approach $4 billion, or over one hundred seventy times 2018’s MRAM revenues.
“Sweeping magnetic field at +/-2 Tesla without any liquid cooling system, and extracting the hysteresis curve of MTJs in less than a second is a breakthrough for STT-MRAM testing and the result of years of research and engineering,” said Siamak Salimy, Hprobe’s CTO. “This is an important step for Hprobe’s customers in their journey to bring STT-MRAM technology at sub-20nm process nodes in mass manufacturing.”
STT-MRAM technology requires devices to be tested under magnetic field to extract characteristic physical parameters critical to assess on quality of operation of the memory. Hprobe‘s new perpendicular magnetic generator is capable of reaching 2 Tesla in a bipolar mode to switch the entire stack of magnetic layers of the STT-MRAM MTJ. The ultra-compact generator with a total volume of less than 30cm3 does not require any liquid cooling system and comes with an RF probing system used to perform the hysteresis curves of MTJs in a record testing time.
* The conference will take place on Monday, August 5 at the Santa Clara Convention Center and Hprobe will present in the Track #1 session on MRAM Development at 3.30pm.
About Hprobe: Founded in March 2017 and based in Grenoble (France), Hprobe is a spin-off company of SPINTEC (one of the leading spintronics research laboratories worldwide.) The company markets equipment for wafer level testing of magnetic devices in the semiconductor industry.
