3D magnetic field Wafer Prober

Hasten your tests and your development

Time spent to test wafers increase chip costs and magnetic devices needs to be tested under magnetic field sweep. We have the unique technology to achieve ultra-competitive testing time for magnetic memory (STT MRAM) and sensor devices (TMR Sensors).
Our product is based on a patented fast sweeping 3D magnetic generator associated with top class control and sensing instruments. Built to test devices fast at high field, it is all set ready to use.
No more test development needed to tests your magnetic devices, we test fast and also fasten your technology development by reducing your test development time.

3D Magnetic Wafer Prober … Flexible

The Hprobe equipment is a plug and play 100 mm to 300 mm automated wafer prober for magnetic devices and sensors. Our wafer prober is the preferred tool for wafer level characterization and testing under magnetic field. It uses a patented 3D magnetic field generator and state of the art, customizable, commercial hardware to bring a full test solution for all magnetic devices, from sensors to STT MRAM. A full software for wafer prober testing automation is available which includes the magnetic sources generation, a set of pre-defined tests for electro/magnetic parameter extraction on thin films materials, STT MRAM and TMR Sensors.

Wafer Prober

The Hprobe tester is the preferred tool for wafer level characterization and testing under magnetic field.

It uses a patented 3D magnetic field generator and state of the art, customizable, commercial hardware to bring a full test solution for all magnetic devices, from TMR sensors to STT MRAM, for R&D and manufacturing.

The tool is built on the standard industrial automated wafer prober of your choice.

3D Magnetic Field Generator Technology

Hprobe has developed a unique patented technology of multidimensional magnetic field generator for STT MRAM and TMR sensors wafer level characterization and testing.

With our 3D generator technology, each magnetic field spatial axis is driven independently. User can apply and control the magnetic field in any direction of space, as well as generate rotating fields.

Calibration

Hprobe Magnetic ATE is provided with a calibration kit for user to freely generate any type of 3D magnetic field patterns.

The calibration kit consists of a 3D magnetic sensor placed on an automated system within the prober. All driven from the software for user to evaluate the exact field strength at the DUT position.

Instruments

Hprobe ATE is using top class state of the art control and sense instruments to provide user a unique and reliable experience.

The instruments could be specified by the user and are controlled by the test program which is built to give all the features for easy installation of new instruments or to upgrade them over time.
