WLA5000-MRAM

As MRAM development progresses and major companies see it as a potential replacement technology for DRAM and NAND, the characterization of STT, SOT, and other MRAM devices at wafer level becomes more and more critical.  Combining our WLA5000 Wafer Analyzer with our revolutionary PULSAR-8000 Pulser System, ISI's WLA5000-MRAM system is ideally suited for this task.

​

While many MRAM development centers may have their own experimental test setups consisting of various off the shelf instruments, released in 2009 ISI was the first and only to develop a fully integrated solution addressing the needs of production level testing of MRAM wafers.  The PULSAR-8000 is the most advanced turnkey MRAM measurement system available today.

​

Our proprietary magnet portfolio includes a vast array of user-interchangeable electromagnets, ideally suited for inplane, perpendicular, 3-axis, and high-field applications.  All of our magnet configurations are designed with high-performance in mind, in producing low remanent fields, high magnetic field strengths, and large uniformity volumes across the area under test.

​

The PULSAR-8000 is optimally matched with our proprietary probecard interface to produce programmable pulses as low as 500pS, with in-situ ability to rapidly perform measurements on the MTJs within microseconds after pulsing.  For applications where higher throughput is desired, the PULSAR-8000 can be equipped with multiple channels, providing parallel measurement capability.  An optional RF probecard interface is also available for applications demanding pulsing and measurement operations beyond 1Ghz.

​

In an MRAM production environment the WLA5000 MRAM Analyzer offers high throughput device performance verification as well as feedback to Wafer Process control. Options like Magnet configurations, probecards, and Thermal Chucks allow customers to customize the system to their specific needs.

​

The WLA5000 MRAM Analyzer can be integrated with a variety of industry standard Automated Wafer Probers to characterize magnetic properties of finished devices or test structures, under hot or cold environmental conditions.  Our proprietary software supports a full array of engineering and production interfaces, data logging, grading, and normalization, and allows for customers to develop their own software modules.
